crl-16435	Urbano, Cristóbal; Zhang, Yin; Downey, Kay; Klingler, Thomas	Library Catalog Log Analysis in E-book Patron-Driven Acquisitions (PDA): A Case Study	2015	15	.pdf	application/pdf	8613	247	47	Also, although there has been a long history of studies on the use and users of OPACs (Online Public Access Catalogs) since their introduction in libraries, with most research using transaction log analysis methods, this approach has not been used to study the use of the library catalog as a way to access e-books, nor to study PDA programs.4 Over the last few years, several studies on e-book use and users reveal a mixed im- age involving both success and failure of e-book usage in libraries.5 Some studies have an interesting focus on the ways users discover and access e-books, but few trace the users’ path from the OPAC to the commercial provider platform. The answers to these questions will help establish to what extent the catalog is used for PDA e-book discovery and whether or not more frequent e-book use is linked to catalog searches and full bibliographic record displays.	cache/crl-16435.pdf	txt/crl-16435.txt
