College and Research Libraries be used in conjunction with the exhibition, this catalog stands by itself as a fine descrip- tion, in word and picture, of what is surely one of the best privately-owned collections of manuscripts, and as such, it will retain its meaningfulness and usefulness long after the manuscripts have been removed from the exhibition cases.—Joan H.

Distributed by T h e Illini Union Bookstore, Champaign, Illinois, 1958. 62p. (Photolithoprint- ed). $1.75. Six papers are published in this booklet, four of them for the first time. They present the results of research in a variety of tech- niques, applied to individual institutions, and then to a specific subject area. T h e au- thor is assistant professor of library science at the University of Illinois Library School. A review article, "Four Aspects of Library Cooperation," is a summary of available studies on interlibrary services. I t discusses in turn union lists, union catalogs, guides to collections, and interlibrary loans; and con- cludes with a statement of the principles which have made for success in recent co- operative ventures. T w o papers report on an examination of library resources at Northwestern Universi- ty. T h e first, " T h e Development of Library Resources at Northwestern University," is reprinted from University of Illinois Library School Occasional Papers, No. 26 (February 1952). I t surveys the historical development of the collections, emphasizing their rapid growth since 1920 and describing briefly certain outstanding collections. A statistical analysis of the collections of the University Library at Northwestern Uni- versity is summarized in "A Case Study of Growth in Library Resources by Subject." T h e Library has maintained since 1918-19 statistics showing the number of cataloged volumes by classes. Using these and other data, mainly unpublished, D r . Jackson has examined all subject classes to determine patterns of growth. H e finds that most sub- jects did appear to follow definite patterns, that certain subjects have regularly shown growth superior to the general rate of incre- ment, and that others have regularly lagged behind. T h e factors which have influenced this growth are reviewed in concluding para- graphs. A n experiment using the shelf list of the library is described in the paper, "Subject Distribution of the University of Illinois Li- brary." T h e result of this investigation is a tabular presentation for twenty-nine subjects, showing the number of volumes and the per- centages of the total. Comparison of this ta- ble with tables for the Harvard University Library and the libraries of Northwestern University, reproduced here, show certain "striking similarities." However, "the small sample makes further investigation necessary to determine whether they represent a pat- tern characteristic of university libraries." "Resources of Midwestern Research Li- braries in the Hispanic Literatures" is re- printed from Hispania, X X X V I I I (1955), 476-80. Data furnished by nine university li- braries and the Newberry Library, and by the appropriate faculty members, were used for a statement of specific strengths and weaknesses in peninsular Spanish literature and in Spanish-American literature. For the latter subject, a test was also made of the extent to which acquisitions programs were bringing currrent books to the area. Titles of 169 monographic items from the 1949 Handbook of Latin American Studies were checked against holdings. This check showed that the libraries as a group held ninety-five titles. T h e same list of current books was also the basis of an experiment reported in "Spanish American Literature in Five Euro- pean National Libraries." A check of the catalogs of Libraries in Madrid, Paris, Brus- sels, London, and T h e Hague showed that these libraries as a group held only a third of the titles, fewer than the research libraries of the Midwest. T h e Studies make several contributions to the understanding of library resources. They are informative in new ways about the col- 258 COLLEGE AND RESEARCH LIBRARIES lections of the institutions studied. As exam- ples of quantitative measurement, concisely reported, they provide models and lines of inquiry for further investigation. Finally, the conclusions set down, scrupulously drawn from the evidence presented, are matter for reflection by all librarians concerned with acquisitions policy and its implications.— Harry W. Hart, Columbia University Librar- ies. International L a w Classification Classification for International Law and Relations. 2d ed., rev. and enl. By Kurt Schwerin. New York: Oceana Publica- tions [1958]. This work is based on the classification scheme developed for the University of Vir- ginia Law Library, originally published in 1947; it is currently used at the Northwestern University Law School Library. T h e schedule is divided into three parts: treatises on international law, treatises on international relations, and official publica- tions, reports, and documents. Private inter- national law, included in the first edition, has now been dropped; it is suggested that it be classed with domestic law. This ar- rangement follows the practice of the ma- jority of law libraries which generally sepa- rate documentary materials from commen- taries and treatises. I n international law, its wisdom is open to serious question since it separates items published by the League of Nations, United Nations, and other agencies from works about these organizations. T h e Library of Congress J X scheme keeps such materials together and appears superior in that respect. Furthermore, the distinction be- tween international law and relations is of- ten arbitrary. Books on international dis- putes, for example, are classed with inter- national law; boundary disputes, however, with international relations; treaties and al- liances appear in both sections. T h e scheme uses a two-digit decimal nota- tion with expansions up to five digits, with- out a decimal point. Letter codes for interna- tional agencies and their organs are provided whenever applicable; a general list of coun- try symbols is appended to the schedule. Mnemonic features are few; i n fact, the decimal principle appears to have been used primarily because of the flexibility it offers in interpolating new numbers and expand- ing the schedule as new topics arise; its other outstanding features have not been fully utilized. A comparison with the first edition shows that the expansion has been considerable: the index about doubled in size, the number of assigned symbols (without country or agency subdivisions) has grown from over one hundred and fifty in the first edition to over two hundred and fifty in the second; more than one hundred and ten numbers have been added, ten dropped, about five changed (relocated). T h e revision was neces- sitated not only by the rapid growth of inter- national agencies after W o r l d W a r I I , but also by the oversimplified approach of the original edition to the arrangement of the League of Nations documents which have now been completely reorganized. T h e schedule has many outstanding fea- tures: a comprehensive index, a complete list of country symbols, helpful examples of call numbers, and an extremely useful scheme for publications of the various international organizations. Its author recommends it for small libraries which might find the Library of Congress J X classification too detailed and too cumbersome to handle. One cannot help wondering about the wisdom of labeling an international law collection as "small" for, if it has research uses, it is bound to grow in- definitely and to reach the complexity of a "large" library. T h e 100-per cent expansion of the scheme under review, apparently indi- cated after ten years, strongly suggests that it would be safer, for any research library, to adopt the detailed classification of the Li- brary of Congress which has the additional advantage of a continuous revision. T o an undergraduate library, however, the Schwerin classification should provide a comfortable framework, in many ways superior to the current edition of the Dewey Decimal scheme. —Vaclav Mostecky, Harvard Law School.
