The enhancement of Sheffield City Polytechnic's online circulation control system

This article updates a previous account of the automated circulation control system operating at the Pond Street Site Library, explaining how original plans for automation have evolved. An outline is given of the kinds of problem encountered with the original system design (availability of files, storage capacity, currency of data), and of remedial measures taken. The benefits of the enhanced system are assessed along with a brief discussion of recent developments concerning the extraction of more detailed management information.
