    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 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
