“…Most of these have included multiple overlap data and analysis. However, few have applied the rudimentary statistical safeguards listed in Buckland et al (1975). These studies often used random samples assuming implicitly but with no justification that the underlying distribution was uniform.…”

“…They rarely presented confidence levels for their conclusions and several were studies of just journal titles. Some of the papers since Bearman and Kunberger (1977) and Buckland et al (1975) have eliminated many of the statistical analysis and data collection sampling problems by being exhaustive: they used the complete population (all articles in all sources under study) and stated the actual TO values (Hasso, 1984;Poyer, 1984, etc.). These do present credible data.…”

“…A theoretical paper by Buckland, Hindle, & Walker (1975) contains excellent cautions for conducting overlap analysis. The paper primarily addressed overlap among library monograph holdings but many of the basic concepts in methodology are applicable to journal overlap studies.…”

“…The general discussions of overlap theory in the literature have not addressed these combinations of sources systematically and TO values have rarely been systematically computed between all possible unions of sources in a collection or universe of secondary sources. The literature does contain partial analyses of ensembles but does not address them in a consistent or complete manner (for example Bearman & Kunberger, 1977;Buckland, Hindle, & Walker, 1975;Poyer, 1984). Obviously, the number of such unions can easily get unwieldy.…”

This investigation reviews the research into journal coverage overlap of the secondary literature indicating the uneven development in this research during the past 30 years and introduces a prototype extension to the traditional definition of overlap. The products of abstracting or indexing services are referred to as secondary sources. Journal coverage overlap (traditional overlap) has been classically defined as the ratio of the number of either journal titles or articles in the intersection of two secondary sources to the number in their union. The extension to the classical definition proposed begins with this traditional definition and proceeds to incorporate the relative sizes of the sources into a matrix of dissimilarity values. Matrices for both the traditional definition and its extension are computed for two universes of secondary source ensembles. These matrices are formed by comparing all possible unions of sources in a universe of secondary sources. Multidimensional scaling analysis is applied to graphically demonstrate this modified concept of coverage overlap and a naive secondary tool selection algorithm is presented. © 1990 John Wiley & Sons, Inc.

This study examined the feasibility of automating the labor-intensive process of collection analysis. Collections in botany and• he growing trend toward research library participation in cooperative collection development agreements has prompted collection managers to seek consistent means to evaluate and compare their collections. Unfortunately, most methods currently available are labor-intensive. The purpose of this study was to test the feasibility of using the databases of the bibliographic networks for computerized collection analysis to reduce the labor required.The project was formally initiated in summer 1985 when the Online Computer Library Center (OCLC) and the Research Libraries Group (RLG) were invited by the Committee on Institutional Cooperation (CIC) to participate in a meeting of its science bibliographers and collection development officers. The meeting explored the potential for cooperative collection development among CIC institutions. Discussions with participants and program planners suggested that science and technology collections would be good subject areas for study.

Collection Overlap as a Function of Library Size: A Comparison of American and Canadian Public Libraries

Random samples of monographic materials from American and Canadian public libraries were matched with the collections of similar libraries of different sizes. Materials with a publication date earlier than 1970 were excluded in order to reduce the sample size, to minimize the effects of comparing older and newer libraries, and to increase the relevance of the findings for resource sharing through contemporary on-line computer-based networks. A strong positive correlation appears to exist between percentage find rate and target library size, with regression analysis suggesting linearity over a wide range of collection sizes.
