T h e symposium reported in this modest volume represents an a t t e m p t by the School of Library Science of the University of Southern California to stimulate interest in i n f o r m a t i o n retrieval, which is one aspect of documentation. T h e program consisted of three general presentations on the p l a n n i n g , nature, a n d needs of i n f o r m a t i o n retrieval; two reports on machine translation; three outlines of i n f o r m a t i o n retrieval systems utilizing computers; two descriptions of elec- tronic devices a n d their uses; and, finally, a short p a n e l discussion. T h e symposium opened with a discussion by R o b e r t Meyer of the needs of the user of information, largely in terms of the user in the special library. T h i s was followed by papers of H . J . R. Grosch (IBM) and Mer- ritt Kastens (Stanford Research Institute), clearly setting forth the objectives of infor- mation retrieval. All three presentations were very explicit as to the type of informa- tion needed by the scientific a n d technical specialist, including e x p l a n a t i o n of the kind of occasion calling for speed, which has been one of the primary factors in attempts at mechanization of the information-finding processes. It should be emphasized that the approach to knowledge represented in the machine methods discussed by these speakers was essentially a subject one. T h e machine translation section of the conference, covered by H . P. E d m u n d s o n a n d D. G. Hays of the R a n d Corporation, formed a very lucid introduction to the sub- ject. T h o s e who a t t e n d e d the symposium must have been well p r e p a r e d to tackle the papers o n mechanical translation in the pre- prints sent o u t for the I n t e r n a t i o n a l Con- ference on Scientific I n f o r m a t i o n held seven m o n t h s later. All of the terms used to de- scribe the machine translation procedures have been explained for the layman. D u r i n g the symposium, three i n f o r m a t i o n retrieval systems were described by H . P. L u h n (IBM), D o n Andrews (U. S. P a t e n t Office), a n d Harley T i l l e t t (U. S. Naval Ord- nance T e s t Station, China Lake, Calif.). T h e s e showed how machines designed for mathematical purposes could be utilized to find certain types of i n f o r m a t i o n . I n all three cases the organization of knowledge was rearranged to fit the computer. L u h n ' s "auto-encoding" of documents is an inter- esting system. "Auto-encoding" is a subject- entry method based o n the choice of key words whose importance is determined by their statistical frequency in the documents analyzed. T h e weakness of the method for broader application lies in the fact that many authors, for aesthetic reasons, delib- erately try not to use the same m a j o r sub- ject word twice in close proximity, prefer- ring as many synonyms as feasible to avoid annoying the reader with constant repeti- tion. W i t h o u t a very fancy thesaurus, this would tend to spoil the statistical averages a n d make all key words of equal value. Til- lett's p a p e r mentioned some psychological factors affecting the adoption of machine methods for information searching. T h e s e factors, notably d i s a p p o i n t m e n t that the ma- chine was so slow a n d that it could not do everything for the client, could be overcome by educating the user not to ask a machine a question that could be answered better with a dictionary catalog, or, in this case, the Uniterms system; a n d also by constantly r e m i n d i n g the client that any machine is a mechanical moron created to perform tedi- ous or repetitious tasks, b u t not to d o any- thing r e q u i r i n g m u c h intelligence. N o i n f o r m a t i o n systems were described of the type which utilize machines specifically for bibliographic r a t h e r that mathematical or statistical purposes, such as semantic fac- toring a n d the Western Reserve Searching Selector. However, general features of sev- eral machines for i n f o r m a t i o n retrieval were presented by Peter Worsley (Benson-Leh- ner), who described a kind of R a p i d Selector called FLIP, a n d by R o b e r t Hayes (Mag- navox), who described Minicards a n d Mag- nacards, both of which are entirely different M A R C H 1 9 6 0 177 in design a n d operation from computers. T h e panel discussion at the e n d of the Symposium revealed the extent to which its objectives were achieved or missed. Appar- ently the term " d o c u m e n t a t i o n " was not defined at the beginning, for one finds ref- erence among the comments of the panelists (p. 89) to an article of H a r r y Bauer in which d o c u m e n t a t i o n has been described as a means of organizing files of letters a n d pamphlet-like material, a misconception al- most as common as the one which defines d o c u m e n t a t i o n primarily in terms of the care a n d feeding of data-processing machines. T h e field of d o c u m e n t a t i o n is much broader than either of these views. A " d o c u m e n t " is any m e d i u m c o n t a i n i n g recorded evidence of intellectual endeavor. " D o c u m e n t a t i o n " is used in the narrow sense by historians to mean the process of citing written evidence to substantiate a statement of fact a n d also as the n a m e for such evidence. T h e word is used in the broad sense by those working with collections of data, or i n f o r m a t i o n of any kind, to mean any process connected with the "identification, recording, organiza- tion, storage, recall, conversion i n t o more useful forms, synthesis, a n d dissemination of the intellectual content of p r i n t or any other recorded m a t e r i a l s . " 1 T h e d u a l m e a n i n g of the word " d o c u m e n t a t i o n " is q u i t e clear if one remembers that a historian will accept the fact that a decisive battle was fought at Hastings in 1066, b u t will insist on "docu- m e n t i n g " a statement that victory in this battle was influenced by the ability of heav- ily armored N o r m a n knights to fight on horseback, because they rode a new breed of horses large e n o u g h to s u p p o r t a knight in full armor, while t h e English rode to the battle field on small horses, then had to dismount a n d fight on foot. T h e document- alist, on the other h a n d , will treat bat- tle, place, date, English knights, N o r m a n knights, infantry, cavalry, full armor, light armor, big horses, a n d little horses impar- tially as " i n f o r m a t i o n " to be processed, stored, a n d recovered. T h e reasoning of the historian, t h e thesis for which he had to cite chapter a n d verse, will only find its way into this body of i n f o r m a t i o n through the fur- ther addition of some generalized subject headings, such as "tactics," "military art and 1 R a l p h R.

( I t a l i c s a r e t h e r e v i e w e r ' s ) . science," "military history, medieval," or "armies—equipment." Incidentally, this ex- ample points u p a n o t h e r problem in L u h n ' s "auto-encoding": the significant ideas or conclusions in a d o c u m e n t are not neces- sarily expressed in precise terms suitable for storage a n d retrieval, while the wordy argu- ment used in establishing them may not be worth preserving. ( T h e example given here is the late Carl Stephenson's Big Horse T h e - ory of the Battle of Hastings.) If the m e a n i n g of " d o c u m e n t a t i o n " was not made clear to the librarians on the panel of the symposium, it is also obvious that the necessities of library work were equally vague to the machine a n d system makers present. At one p o i n t (pp. 96-97) it was suggested that it is the job of the " m o t h e r " professional organization in the library world (presumably ALA) to formu- late a set of standards for mechanization. T h i s idea seems to crop u p in one form or a n o t h e r at every d o c u m e n t a t i o n conference. It might have a chance of b e i n g adopted if there were somewhere a plain statement of exactly what the machines can a n d cannot do similar to the b e g i n n i n g made by Claire K. Schultz at the recent meeting of the American D o c u m e n t a t i o n Institute. It also might be acted u p o n if there were some in- dication of interest in p r o d u c i n g a kind of machine that would fit library procedures, rather than d e m a n d i n g that these experi- ence-tested processes be t u r n e d upside down to fit a machine designed for a counting- house. Actually, there are some routines which could be mechanized right now. For example, the practicing cataloger who does original cataloging could use something in the line of mechanical subject i n d e x i n g to do these things: (1) take the raw terms which describe the subject matter of the book in h a n d , compare these with the standardized list of subject headings, a n d convert raw terms i n t o the equivalent standardized forms; (2) take the title (or subtitle or sup- plied title) of the book as representative of its topic, together with the standardized subject heading most nearly descriptive of this topic, a n d compare with other titles al- ready listed u n d e r the same h e a d i n g to see whether the book being cataloged fits the category (if not, the cataloger may either try other subject headings t u r n e d u p in step (1) or repeat the first process with f u r t h e r 178 C O L L E G E A N D R E S E A R C H L I B R A R I E S instructions refining the search among stand- ardized headings); (3) repeat the same com- parison a n d checking procedures with the classification tables. It might be possible to do both the subject heading a n d classifica- tion comparisons simultaneously. Present machines are capable of p e r f o r m i n g this kind of look-up and comparison operations. D u r i n g the symposium, the information needs of the scientific world, at least, were very clearly described, a n d a few of the imaginative methods which have been made by scientists a n d engineers to answer these needs were outlined. It is d o u b t f u l that the conference did much to end the Great Schism between the librarians, who under- stand the m a g n i t u d e of the information storage a n d retrieval problem in its totality, a n d the p r o p o n e n t s of mechanization, who see only the failures of present systems in the highly specialized fields with which they are familiar. Dean Boaz a n d the library school of the University of Southern Cali- fornia are to be commended on making a sincere effort to open channels of commu- nication between the two viewpoints.— Phyllis A.

Y.: Ozalid Division of General Aniline and Film Corporation, 1959. 88p., $3.75. T h e overhead projector is an audio-visual tool that has a p p e a r e d since 1950 a n d made its presence felt q u i t e markedly in industrial audio-visual departments. It is beginning to a p p e a r at technical a n d academic meetings as an extension to the services offered by the older projection methods. It combines the freedom a n d spontaneity of the black- board with the precision a n d artistry of the slide projector, while a d d i n g a n u m b e r of facilities not f o u n d in these standard tech- niques. Ozalid does not make overhead projectors, b u t it does produce e q u i p m e n t a n d supplies used in p r e p a r i n g transparencies for these projectors. T h e bulk of this superbly illus- trated volume deals with the preparation of transparencies by the diazo process. T h i s is to be expected as Ozalid is the outstanding producer of diazo materials in this country. Sections of the book are given to homemade transparencies, T r a n s f e r o n (diffusion-trans- fer), transparency m o u n t i n g techniques, transparency design, a n d overhead projec- tion techniques. Much of this m a n u a l could be used to improve presentations based on the blackboard a n d slide projector, and it will certainly add to the versatility of the d e p a r t m e n t using an overhead projector. T h e r e is a short bibliography at the end of the book referring the reader to sixteen recent reports on overhead projection. T h e r e is also a two-page listing of Ozalid audio- visual products, which serves as a glossary to the many terms savoring of jargon that appear in the book. T h e illustrations with which the book is filled serve to simplify the description of techniques a n d exemplify the visual method at its best. T h e profusion of trade-names in the text tends to minimize the effectiveness of this portion of the book. The volume can be recommended for all li- braries engaged in or about to become in- volved in audio-visual work.—Hubbard W. Ballou, Columbia University Libraries. Soviet Publishing Publishing in the U.S.S.R. By Boris I. Go- rokhoff. (Indiana University Publications. Slavic and East E u r o p e a n Series, Vol. 19.) [Bloomington, Ind.: I n d i a n a University, cl959.] xvi, 307 p. $3.00; cloth, $6.00. I n spite of the recent burgeoning of arti- cles about Soviet methods of disseminating scientific information there has been a need for full length studies in English which would give a balanced presentation of Soviet libraries, bibliography, a n d publishing in general. T h e Council on Library Resources, Inc., has acted to fill this need by s u p p o r t i n g Paul Horecky's Libraries and Bibliographic Centers in the Soviet Union, Volume 16 in the I n d i a n a series, a n d its companion vol- ume on publishing. T o g e t h e r they form a valuable survey of the current scene. T h e competence in research on Soviet Russia, built u p in large measure since W o r l d W a r II by the area institutes in American uni- versities, appears to have been joined hap- pily with experienced librarianship i n the production of these studies.
