    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

    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
    Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards

    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
    The Book House is an interactive, multimedia, online public access catalogue designed to support casual, novice users in information retrieval. It uses icons, text and animation in the display interface in order to enhance the utility of the system. A prerequisite for the design of The Book House was a cognitive analysis of users' information needs and search queries. The paper describes The BookHouse and discusses its relevance as a solution to the current OPAC developments

    Abstract
    Browse searching of online catalogs and electronic indexes is a popular means of retrieving information, but some subject heading lists are so extensive that browsing them can be difficult and time-consuming. This resaerch tested one way of presenting a browse interface to reduce the amount of scanning of subject headings required. It found that a hierarchical presentation of headings reduced the amount of scanning required by more than 50% without any reduction in the effectiveness of the search. Better browsable displays of this sort can improve the efficiency of searching but appear not to alter effectivenenss

    Abstract
    The very nature of traditional interfaces to databases tend to hide their information content and makes it very difficult for a user to build a conceptual model of their contents. Traditional libraries, however, are designed to make their contents and their arrangements clearly visible and capable of browsing. Describes a small demonstration system aimed at making the contents of an OPAC capable of being visualised by users and designed as part of the HYPERCATalog effort

    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
    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
