    Abstract
    Reports results of a study to evaluate the OPACs in 12 Canadian academic libraries, using a checklist of functional capabilities and interface features of an ideal OPAC system, to serve as an evaluation standard or benchmark for evaluating the strenghts and weaknesses of the OPACs. Findings suggest that, among the 10 areas evaluated, screen displays is the best developed area, and subject search aids is the weakest. Identifies possible directions for the future development of OPACs and suggests areas for future OPAC research

    Abstract
    Reports and combines the results of 2 assessments of full bibliographic displays in the online catalogue of academic libraries. The first assessment evaluated displays in 12 OPACs while the second evaluated displays in 10 WWW based catalogues. Displays were evaluated against a checklist of desirable features derived from published display guidelines. Results showed that, on average, displays in OPACs scored 58% and displays in Web catalogues scored 60%. Discusses some of the weaknesses identified by the assessments, focusing on those found in the majority of the displays evaluated

    Abstract
    In a study at the University of Toronto libraries, observers recorded protocols for 100 OPAC search sessions. This article reports on the analysis of these protocols, and examines zero-hit subject searches in particular to explore the the effectiveness of various conversions of users' queries to improve recall. Although the number of zero-hit subject searches analyzes was small, this exploratory study yielded some findings that merit consideration in efforts to improve subject access in OPACs.

    Abstract
    In a 1990 study of 5 different online public access catalogue (OPAC) systems at 5 Ontario university libraries, 2916 undergraduates, graduates and faculty were interviewed to determine their satisfaction with the computerised catalogue. Presents the results for the entire sample as well as the findings for each OPAC/site. Sets out 6 major findings and makes several recommendations for future research involving OPACs
