Compares features of online public access catalogs (OPACs) at six British universities: (1) Cambridge; (2) Hull; (3) Newcastle; (4) Surrey; (5) Sussex; and (6) York. Results of keyword subject searches on two topics performed on each of the OPACs are reported and compared. Six references are listed. (MES)

This report describes a computer-monitoring study of users of the Ohio State University Libraries' online catalog, an established and heavily used information retrieval system. Designed for end users, online library catalogs require little or no formal training, and often replace an existing manual system. Data were gathered unobtrusively by…

This document provides a description of library staff training for keyword/Boolean searching on the library's online catalog, LUIS (Library User Information System), at Indiana State University.

This essay offers suggestions to make online public access catalogs (OPACs) less idiosyncratic and more usable. Discussion covers qualitative difference between online catalog and predecessors, challenge of debunking assumptions, skills for success, maintaining an instructional perspective, catalog development for the people by the people, and the…

This review of the literature on the effect of information overload on users' information-seeking behavior focuses on librarians' opinions about the number of references that constitute too many, and users' preferences for maximum numbers of references from online searches, online public access catalog postings, and manual indexes.

Presents a model for the design of online catalog subject access based on three principles: the uncertainty of subject indexing, the need for greater variety in searcher's queries, and the complexity of the search process. The proposed system is based on existing Library of Congress subject cataloging. (EM)

A survey at the University of Houston examined factors related to subject searching success in online catalogs, including: extent of subject searching; response to unsuccessful searches; reasons subject search is not used; users' awareness of sources of subject terms; and suggestions from users for improving subject searching capabilities. (CLB)

Reviews the literature on user studies in both online catalogs and bibliographic retrieval systems. User problems with both mechanical and conceptual aspects are reviewed and potential sources of problems due either to individual characteristics or system variables are discussed. Possible solutions and areas that need further research are noted.…
