    Abstract
    The MacNOTIS interface development and test used the Apple Macintosh, HyperCard, and MitemView communications Software to develop and test an intuitive interface to NOTIS systems. While the concept and design were viewed favorably by the users, technical and speed issues made the interface too slow for widespread use. MacNOTIS pointed the way to several interface enhancements that should be incorporated in future NOTIS user interfaces

    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
    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
    Discusses and illustrates the essential features of user-system interfaces designed to support end user searching. Presents examples of interfaces to support the following basic information seeking functions are presented: problem definition, source selection, problem articulation, examination of results, and information extraction. Argues that present interfaces focus on problem articulation and examination of results functions, and research and development are needed to support the problem definition and information extraction functions

    The acronym OPAC should perhaps stand for Open, Public, Accessible and Cooperative. Looks at how the OPAC modules available in major European library systems live up to this definition. Discusses 3rd generation OPAC development areas; network access; document types and services included; document ordering and delivery; user interface; retrieval models; communication language; and record enhancements

    Abstract
    Modern online information systems have been criticized as being too complicated for the average information seeker. To overcome this problem interfaces have been developed to assist users at all stages of the information transfer process from searching to analysis and evaluation of retrieval data. However, the effectiveness of an interface will depend on the skills of the user. Further development of interfaces will be aided by the use of Windows and mouse controlled systems

    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
    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
    Librarians find themselves today in a lively period of the evolution of user interfaces to online information. Most of the newer interfaces incorporate graphics, colour and mouse-supported searching to make intiation for the novics user easier and all searching more productive. Describes the University of Delaware's development of DELCAT MacPAC, a HyperCard-based front-end to the university's OPAC, adapted from Cornell University's MacPAC. The focus is on Delaware's customisation of MacPAC for its environment, including the support of remote users, and the testing, use, and distribution of the product

    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
    Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system

    Abstract
    Describes the OKAPI projects and OKAPI's development as an experimental online catalogue system over 10 years, first at the University of Westminster (formerly the Polytechnique of Central London) and subsequently at City University, London. The 1st OKAPI project in 1984 introduced 'best match' retrieval and focused on the user interface design. The 2nd investigated word stemming, spelling correction and cross reference tables as retrieval aids. A comparative study of 2 library catalogues was undertaken in 1987, while in 1988 query expansion and relevance feedback were introduced and evaluated by laboratory tests. In 1990 live evaluation of automatic query expansion was carried out and in 1993 subject enhancement of bibliographic records was investigated. The latest project has examined the design of a graphical user interface to support interactive query expansion. Discusses the research and evaluation of each project

    Abstract
    Information retrieval systems such as library OPACs have been largely designed to give the impression of being single user systems, the existence and activity of other users being hidden from each other. However, informal observations indicate significant collaboration between users despite the fact that existing systems fail to support this. Describes the development of an interface, the Ariadne system, that supports collaboration through the storage and re-use of others' search processes promoting better visualization of the information data structures being browsed and more effective means of communicating the browsing process. Discusses issues relating to privacy and ownership resulting from the storage of users' searches. Argues that introducing support for collaboration into information retrieval systems would help users to learn and use the systems more effectively

    Abstract
    Several studies on OPACs have been made since the early 1980s. However, OPAC development has been governed by systems designers, bibliographic networks and technical services librarians, but not necessarily according to user needs. Existing OPACs demonstrate differences, for example, in the range and complexity of their functional features, terminology and help facilities. While many libraries have already established their own OPACs, there is a need to bring together in the form of guidelines or recommendations a corpus of good practice to assist libraries to design or re-design their OPACs.
