Abstract: Reports an investigation into the feasibility of usinf tutorials to train students to use on-line public access catalogues (OPACs). The library developed instructional software which conveys a conceptual model of an on-line catalogue and how it works. Reports the results of an experiment conducted to compare the effectiveness of the computer tutorial and the standard introductory classroom lecture on using the OPAC at the University of Toronto

Abstract

The University of Toronto hopes to encourage development of a campus-wide information system consisting of many walk-up-and-use components. The first component to be developed was an instructional program for users of the library's online catalog. The interface had to be attractive, usable by novices, and flexible enough to carry the content. Much effort was expended in ensuring that it met these criteria. User testing played an important role in the design of the interface. The design and testing of the system's entry point, navigation aids, and templates for spatial arrangements of information on the screen are discussed

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

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

In an experiment to evaluate the effectiveness of a concept based computer tutorial for training OPAC users, it was found that Toronto University students who viewed the tutorial performed significantly better on search tasks than those who received no instruction. Reports the results of a second experiment to investigate the effectiveness of the computer tutorial. 15 students viewed the computer tutorial and another 15 students served as a control group and did not receive any instruction. Results showed no significant differences in performance between the students who viewed the computer tutorial and those who did not receive any instruction. Discusses the differences between the results of the 2 experiments in terms of the characteristics of the participants and the characteristics of the OPACs and relates these findings to the findings of other studies on concept based instruction and offer suggestions for future research

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

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

Reports results of an evaluation study of 3 WWW based prototypes for bibliographic displays developed as part of an ongoing research project at the Faculty of Information Studies, Toronto University. The development of these prototypes builds upon results obtained in earlier phases of the project that addressed issues of both the content and form of bibliographic displays in OPACs. Anticipation of continued growth in the number of catalogues available through the WWW, combined with research evidence that existing Web based displays have not shown improvement over their text based counterparts, motivated the development of these prototypes for use on the Web. Reports findings from a focus group evaluation of the 3 prototypes and makes suggestions for future research
