    Abstract
    Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.

    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
    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
    Outlines the progress of HyperLib, research which began in 1993 to develop a hypertext interface to the online catalogue and other databases at the University of Antwerp. A human factors oriented design methodology was adopted. A user survey was carried out. The project has focused on development of electronic guides and manual and interfaces to access an academic bibliography database and the UDC subject classification scheme. Evaluation is being carried out in 1995

    Abstract
    Presents a chart comparing the subject access features available on 4 different catalogues (card catalogues, GEAC, MELVYL and NOTIS) and develops a method for 'walking through' subject searches in different catalogues using a 'naive subject searcher' model in which searching behaviour is determined by 3 basic characteristics: a lack of understanding of how information is stored, indexed, and retrieved in library catalogues; a preference for the simplest available mode of interaction with the catalogue and a lack of any searching strategy or tactics beyond simple 'subject searching'. A complete 'naive Subject search' of the GEAC 8000-based GLIS on-line catalogue is presented, and sample NOTIS and MELVYL screens are discussed

    Abstract
    Describes a research project which studied the interaction between screen design, menu interfaces and the search results obtained by users. A literature review surveys the research in theses areas, including methods used to evaluate OPACs. Draws up a set of design guidelines for menu interfaces. Two versions of the OPAC a Porirua Public Library in New Zealand were available, 1 used 'good' menu design and the other contravened the guidelines. The difference between 'no-hit' rates for the 2 terminals was not statistically significant, indicating that other factors must be considered

    Abstract
    Although several attempts have been made to devise simplified shelf arrangements for children, little consideration has been given to developing a simplified automated library catalogue. At Denver Public Library in the USA a catalogue has been devised enabling users to search via graphical symbols. Results of research into children's use of library catalogues was used as a basis for creating the system. Librarians must be prepared to re-examine how far existing systems meet the needs of their users

    Abstract
    The presence of different interfaces to use online catalogues has caused difficulties, particularly for remote users. To tackle this problem 13 university campuses in New South Wales linked their online catalogues together to form a network called LIBLINK (a subnet of the Australian Academic Research Network, AARNET). The key to the success of the network is the user searching software, PINS (Practical Interface to Network System), a set of fourth generation language software tools. Suggests that LIBLINK can be a simple solution for other libraries around the world

    Abstract
    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
    Current user interfaces for textual database searching leave much to be desired: individually, they are often confusing, and as a group, they are seriously inconsistent. We propose a four- phase framework for user-interface design: the framework provides common structure and terminology for searching while preserving the distinct features of individual collections and search mechanisms. Users will benefit from faster learning, increased comprehension, and better control, leading to more effective searches and higher satisfaction.

    Abstract
    An online library catalogue served as a testbed to evaluate an interactive query expansion facility based on relevance feedback for the Okapi probabilistic term weighting retrieval system. The facility was implemented in a graphical user interface (GUI) environment using a game-board metaphor for the search process, and allowed searchers to select candidate terms extracted from relevant retrieved itms to reformulate queries. The take-up of the interactive query expansion option was found to be lower, and its retrieval performance less effective, compared to previous tests featuring automatic query expansion. Contributory factors including the number, presentation and source of terms are discussed

    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
    Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction
