- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- 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

- Reports a survey conducted in April 1997 of 136 Japanese WWW and Telnet OPACs from the persepctive of their functions and user interfaces. These included: types of searchable files; access points; kinds of displays; login commands; search methods; Boolean operation; help functions; search history; and browsing of indexed terms. Results indicate a sharp rise in the number of WWW OPACs and problems with the provision of functions and user interfaces by Japanese WWW 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
- The GUI is impacting library application software. Despite this trend, user satisfaction with the GUI has not been documented. The Parke-Davis Pharmaceutical Research Library, USA, undertook a study to determine user satisfaction with the new GUI based Dynix Marquis, as compared with the Dynix Classic OPAC. The study included a survey assessing user satisfaction and a review of overall usage. Survey findings show that the GUI based OPAC was preferred by end users over the text based OPAC. Usage reports supported the survey findings with significantly increased usage after migration

- Abstract
- PACE (Public Access Catalogue Extension) is an alternative user interface designed to enhace OPACs. PACE simulates images of books and library shelves to help users browse through the catalogue. Reports results of a study in which PACE was tested in a college library (Vanier College), in a real operational environment, against a second generation test based OPAC: Best-Seller. Results show that a simple browsable retrieval interface performed as well as a second generation OPAC in terms of retrieval speed and search success. The overwhelming majority of students, however, preferred the browsing capability of PACE through the familiar metaphor of books and library shelves to a text based OPAC

- 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 the results of a research project, conducted by the School of Computing and Mathematics and the Library of Huddersfield Polytechnic, into the problem of matching the user interface of OPACs to the needs of users. The project brought together issues involving: Human Computer Instruction (HCI); system methods in the determinination of user requirements; and user centred design, and prototyping in a sequence of design and evaluation cycles. These cycles applied appropriate HCI styles, techniques and equipment (such as Graphical User Interface (GUI) and a mouse pointing device) and incorporated the lessons of each evaluation, to produce an OPAC user interface, ICARUS, which differs considerably in style, behaviour and characteristcs from those commonly encountered in academic and public libraries. The project concluded by evaluating ICARUS, against the BLCMP OPAC with 38 subjects in the Library of Huddersfield Polytechnic, and demonstrating a significant improvement in performance for different tasks for the ICARUS interface

- Abstract
- Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues
