Explains some observed library circulation frequency distributions through use of a simple stochastic model for the borrowing of books from a library collection. Parameters of the model are described and the model is applied to circulation data from three academic libraries. (Author/SW)

Using Ehrenberg's application of mathematical models to the analysis and prediction of repeated buying patterns of consumers, this study focuses on the concept of library use as a form of consumer behavior. The following hypotheses were tested: designated library user groups will tend to exhibit stable behavioral patterns with respect to the…

Describes a study that used transaction log analysis to investigate the use of subject searching in the University of California's Online Union Catalog, MELVYL. Mathematical models of trends and patterns in the data are presented, problems with subject searching are explained, and remedies to subject searching problems are suggested. (62…
