Undertaken to determine if the pattern of use of library reserve collections found at other college libraries continues to exist at DePauw, this study found that approximately 40 percent of all the reserve collection items never circulated during the entire semester, and that 33 percent of the collection circulated only one to five times during…

Multiple regression analysis was employed to determine three variables which best correlate with circulation: number of books added, full-time equivalent size of student body, and undergraduate and graduate courses offered. A regression equation recommending a predictive value for the number of books to be added was developed; data tables are…

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)

Reports on a five year study of 82 large academic libraries which found that both interlibrary loan lending and borrowing are correlated to collection size. (RBF)

Four models for conceptualizing a circulation matrix containing the number of books borrowed according to subject and majors of student borrowers compare (1) majors; (2) subjects; (3) disciplines, suppressing the distinction between majors and subjects; and (4) majors with subjects. Results of multidimensional scaling analysis of the models are…

The process described in this manual is designed to help small academic libraries systematically study the use of their circulating book collections. Originally developed in 1980, the manual has been used successfully in several small college libraries, both with and without assistance from outside consultants. In most cases, the study can be…

This assessment of the library profession's response to technological innovation focuses on the handling of nonprint collections. Highlights include definition of nonprint materials; basic considerations in conservation and environmental concerns (temperature, dust, light exposure); the problem of security and storage procedures; and circulation…

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)

This report describes the methods used to monitor the loss of library materials at Purdue University's General Library during the last 20 years. Data are provided on the following: a complete facility inventory taken in 1959; spot checks of high loss areas made on the basis of patron requests; an availability study in which patrons revealed the…

Discusses the issue of centralization or decentralization of academic library collections, and describes a statistical analysis of book circulation at the University of Southwestern Louisiana that yielded subject area clusters as a compromise solution to the problem. Applications of the cluster model for all types of library catalogs are…

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)

Presents and discusses the results of a study undertaken at Washington State University to determine whether different subgroups of the library collection had different loss and misshelving rates and, if so, whether the worst problems could be predicted from circulation data. Two tables present the data from the study. (Author/JL)

Presents results of a survey which polled 37 university libraries to determine the attitudes, opinions, and perceptions of map librarians regarding unique security problems, addressing such factors as commercially designed security systems, written circulation policies, and access limitations. Twenty-six references are listed, and appendices…

This paper discusses how the Creighton University Health Sciences Library Serial Department has updated their process of claiming and replacing missing journal issues. The paper is divided into two main parts. The first part discusses the changes in the claiming procedure. The second part discusses how the claims are reported to vendors. Future…

This study tests the widely cited proposition that 20% of a library's books account for 80% of its circulation. Using data collected for a collection development survey, it was found that of the sample of 4,213 books, 799, or 19%, accounted for 79% of the circulation during 1987. In fact, 25% of the books accounted for all of the circulation that…
