Abstract

Reports on the state-of-the art of online catalogues and considers propects for future developments. Describes the background and origins of OPACs. Considers the limitations of second generation systems which are failing to meet the needs of users. Examines new approaches to their design which include: user-centre design, interface design, use of advanced retrieval techniques, and their use in the network environment. Considers future developments of OPACs taking into account developments in other electronic information sources

Abstract

Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.
