    Abstract
    The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

    Abstract
    Reviews the development of the British Library OPAC services leading up to the launch of OPAC 97, offering access to 9 mio bibliographic records and attempts to show the value of a user centred approach in the project management involved in developing such a service as recommended by Human Computer Interaction (HCI) studies. Reviews the evaluation studies of the Online Catalogue, the Network OPAC, a web prototype interface and of OPAC 97 and discusses the results in relation to the OPAC 97 project. Although the OPAC 97 interface made use of various HCI recommendations, user feedback sometimes contradicted these in specific instances, revealing the value of detailed user evaluation in developing services

    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
    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

    Abstract
    Contribution to thematic issue on artificial intelligence, knowledge systems and the future library. Developes the concept of a knowledge interface for library users as an extension of intelligent knowledge-base system concepts. Examines contemporary paths in intelligent decision support, particularly in the role of search intermediaries, to discover the significance of intelligent intermediaries as a solution to unstructured decision support. Illustrates one form of intelligent intermediary with a discourse script. Discusses automatic speech recognition and computer vision

    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
    Browsing is an important aspect of the information-seeking activities of library users and is primarily visual. Second-generation OPACs lack the necessary visual characteristics for browsing. These characteristics may be best implemented through simulation of images of books and library shelves on the computer monitors. To mimic users' mental models of the real world may be costly, however, unless new interfaces can tap into existing sources of information. A possible solution may be found in using the information embedded in the MARC record pertaining to the physical description of a book. Public Access Catalog Extension (PACE) is designed as an alternative interface based on mental images of users and MARC records

    Abstract
    Focuses on the user and human-computer interaction (HCI) aspects of the research based on the Okapi text retrieval system. Describes 3 experiments using different approaches to query expansion, highlighting the relationship between the functionality of a system and different interface designs. These experiments involve both automatic and interactive query expansion, and both character based and GUI (graphical user interface) environments. The effectiveness of the search interaction for query expansion depends on resolving opposing interface and functional aspects, e.g. automatic vs. interactive query expansion, explicit vs. implicit use of a thesaurus, and document vs. query space

    Abstract
    Purpose - The purpose of this paper is to investigate the usability of a web-based OPAC (WebPAC) user interface at the International Islamic University Malaysia (IIUM). It also looks at the applicability of heuristic evaluation in designing a user-centered WebPAC interface. Design/methodology/approach - Based on Nielsen's ten usability heuristic principles, the study focuses on three heuristics only, i.e. aesthetic and minimalist design, match between interface and the real world, and visibility of interface status. Findings - Results of the study found that the WebPAC interface conforms to at least 70 percent usability properties prescribed. Usability problems violated in the interface were identified. Practical implications - The study suggests that heuristic evaluation is applicable in libraries to asses the usability of user interface for online catalogs. Originality/value - Heuristic evaluation could assist libraries in designing user-centered interface for online catalogs.
