College and Research Libraries GRANT T. SKELLEY Characteristics of Collections Added to Alllerican Research Libraries, 1940-1970: A Preliminary Investigation During the years 1940-1970 301 American libraries wer.e re~orted in College & Research Libraries and College & Research L1bran~s News to have added 1,454 collections. In this report the collectwns are analyzed by (1) .type of library, (2) type. of. coll~ction, (3) means ac- quired, and (4) sources of gifts (to academtc hbranes). INTRODUCTION THERE IS A coNSIDERABLE, if not sub- stantial, amount of writing about ''book selection" and "collection building" in libraries of all kinds. Little seems to have been written, however, about the role that has been played among re- search libraries in general by the prac- tice of acquiring collections of library materials-as opposed to adding indi- vidual titles one at a time. It is the pur- pose of this paper to make an informal, preliminary report on an investigation based on one reasonably usable data base, with the hope that it may suggest and contribute to some more thorough and more conclusive studies. American libraries have been growing since colonial times partly by means of acquiring, in bulk, existing collections. But documentation and details of most of these transactions, and of the nature of the collections, are for the most part either lacking or widely scattered and difficult of access. For a fairly recent pe- Grant T. Skelley is assistant professor, School of Librarianship, University of Washington, Seattle. 52/ riod, however, a starting point, at least, exists. From its first issue, dated Decem- ber 1939, College & Research Libraries and, more lately, College & Research Li- braries News (hereinafter referred to as C&RL and C&RL News) have in- cluded, with some variations in presen- tation and arrangement, news of recent acquisitions by libraries throughout the United States and Canada. With certain qualifications brought out later in this report, these published descriptions of what American libraries were adding to their resources in the form of collec- tions provide a sample of what has been going on. The term "research library" is subject to definitions that vary according to in- dividual predilections and persuasions. (One notices without comment the dis- tinction made in the title of the journal used as the primary source for this in- vestigation.) Consequently, no attempt has been made to discriminate among the libraries whose acquisitions were re- ported. With a few exceptions . to be noted, every added collection that was reported in the pages of C&RL and C&RL News, 1940-1970 inclusive ( 1,454 collections in 301 libraries), has been counted and categorized according to ( 1) type of library, ( 2) type of collec- tion, ( 3) means acquired, and ( 4) sources ·of gifts. Definitions are given below. A word about scope. C&RL at first listed people who supplied the journal with information about new acquisi- tions, and these people were called c're- porters." Mention of them was soon dis- continued, and some of the editors of C&RL during the period covered have informed the author that the large ma- jority of the descriptions that appeared (and appear currently) were derived from news-releases, and that virtually all of such announcements they re- ceived appeared, sometimes in edited versions, in subsequent issues of the journal. Other sources accounted for a small number of the collections report- ed. Within that scope-the scope of the news sources C&RL has and the news it published-exclusions in this study include ( 1) Canadian libraries, since there were so few reported; ( 2) one or two instances where the library could not be positively identified from the in- formation given; ( 3) one or two cases where collections were jointly acquired by two or more libraries not in the same system; ( 4) the second or third mention of any one collection; ( 5) those cases where the description was unclear as to whether or not books were acquired as a lot, and ( 6) those collections that were said to have been formed by an agent of the library going on a buying junket. No attempt was made to quantify the growth these collections represented in terms of number of volumes or other units. When given, sizes ranged from two volumes (and other larger quanti- ties as specific) to eight tons to three truckloads to a 14,000,000-item archival collection (that of Ford Motor Compa- ny, given to the Edison Institute in Characteristics of Collections I 53 1965). The years used in the tables are the years in which collections were re- ported in C&RL or C&RL News, and are therefore not necessarily always the years they were acquired. DEFINITIONS Collection A collection was any group of materi- als containing two or more items, with the exception that a run of a single se- rial title was not considered a collection. However, runs of two or more serials were considered to be a collection. Type of Library Academic/ Private-Any academic in- stitution of higher education not sup- ported by state or municipal funds. A unit of a multiunit system was identi- fied and tallied only under the parent institution. Academic/ Public-Any academic in- stitution of higher education supported by public funds. A unit of a multiunit system was identified and tallied only under the parent institution. Other-A library that does not quali- fy as either type of academic library, or as a "public" or ''state" library, i.e., the kind of library that would common- ly be referred to as "special" or would be in a category almost by itself, like the Newberry, Folger, Huntington, etc. Public-With one exception, a tax- supported library serving a city or coun- ty. Branches were tallied by system. The exception is the Library of Congress, in- cluded here on the basis of its tax sup- port. (How its inclusion affects the sta- tistics for public libraries is brought out below.) State-A state library and its branch- es. Branches, such as the Sutro Branch of the California State Library, were tallied as with "public." Type of Collection Author-Used to designate a collec- 54 I College & Research Libraries • January 1975 tion of books by one author, or of the manuscripts of his works, or both. Cor- respondence and "papers'' were cate- gorized as a subject collection (see be- low). Book-Used to designate any collec- tion of printed books, serials, pamph- lets, etc. Genre-A collection of certain types of material, book or nonbook, where author or subject was not the unifying principle: Victorian fiction, incunabula, clay tablets, recorded music of the 1920s, books from one private press, etc. Heterogeneous-Applied to any col- lection that was not distinctly an author, genre, or subject collection, such as the occasional <
