Fuzzy set theory, a mathematical modeling technique that allows for the consideration of such factors as "professional expertise" in decision making, is discussed as a tool for use in libraries--specifically in collection management. The fundamentals of fuzzy set theory are introduced and a reference list is included. (JL)

Operations Research models of the acquisition and storage functions of a library are developed. Rules for selection of materials for a depository are analyzed and models of circulation interference and usage are explored. A generalized model of library costs and benefits is proposed.

Random samples of monographic materials from U.S. and Canadian public libraries were matched with collections from similar libraries of different sizes. Strong positive correlation appears between percentage find rate and target library size, with regression analysis suggesting linearity over a wide range of collection sizes. (Author)

A mathematical model is presented that can be used to predict a library's circulation. (Author)

Examines the issue of OCLC benefits for special libraries in terms of find rates and suggests that special libraries consider OCLC participation when find rates are low. (FM)

This study tested assumptions about self-sufficiency of academic library collections and the paradigm shift to providing access to information stored elsewhere. Inter-library borrowing statistics of Australian libraries were correlated with collection size. The study concluded that collection self-sufficiency is a fallacy and that the information…

Develops an empirical model for predicting the size of an information store necessary to satisfy specified levels of demand. A method for selecting items for retirement with the least adverse impact on the store is suggested. Three tables, three figures, and a 10-item reference list are included. (Author/JL)

Examines traditional conceptions of a library collection, and reveals four major presumptions associated with collections: tangibility, ownership, a user community, and an integrated retrieval mechanism. Explores challenges posed by media, and proposes an expanded concept of collection that considers the perspectives of both user and collection…

Uses bibliometric techniques in the development of a model of the distribution of demand for items in an information store. The hypothesis of hyperbolic distribution and an index of differential demand are also discussed. One table, two figures, and a 10-item reference list accompany the text. (Author/JL)

Examines the distribution of use of items in a large information store and suggests that a simple exponential model describes the process of obsolescence more precisely. Three tables, four figures, and a 17-item reference list are included. (Author/JL)

Discussion of sampling methods used in information science research focuses on Fussler's method for sampling catalog cards and on sampling by length. Highlights include simple random sampling, sampling with probability equal to size without replacement, sampling with replacement, and examples of estimating the number of books on shelves in certain…

Proposes a design for an online serials decision-making and collection analysis system: one which would have the ability to respond specifically to user interest profiles and to integrate locally generated data. (FM)

Defines digital library collections and outlines two classes of collection metadata. Describes the Alexandria Digital Library (ADL) Project approach to collection metadata, including the ADL system architecture and collection guidelines and the format and use of the ADL collection metadata. Appendices include ADL collection metadata and example.…

Presents a method of using library patrons' perceived needs for titles as a means of ascribing scholarly journal collection support and costs to academic programs. (Author/FM)

Describes a study of personal journal subscriptions of science faculty in an undergraduate liberal arts college, St. Francis Xavier University (Nova Scotia). Topics examined include reasons for subscriptions, classification of journals, use of an SDI (Selective Dissemination of Information) service, overlap with holdings of the university library,…
