Using Article Photocopy Data in Bibliographic Models for Journal Collection Management

Abstract

This article describes a method for analyzing the demand for photocopies of individual journal articles for the purpose of making journal selection, deselection, and retention decisions. The study of a specialized library is based on 491 users responsible for more than 48,000 journal article photocopies during the three-year data-collection phase of the project. Cost-per-use analysis was employed to evaluate which journals were most cost-effective to own.

This information was used to make subscription deselection and selection decisions each year. Four years after the study was completed, the number of subscriptions had been reduced more than 45 percent, but the number of photocopies made from journals held within the library (as opposed to borrowed from outside) had increased from 45 percent to 67 percent. The analysis also prov...
