    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
    The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

    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
    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
    A research project at Middlesex Polytechnic is examning the problems of subject access in an OPAC. A series of user studies have been carried out which examined students' use of existing catalogue facilities, which in turn led to the experimental evaluation of various interface designs for an online catalogue. The experiments were primarily concerned with the effect of the following variables on the speed and accuracy of retrieval of specific items, the use of colour, the speed of presentation of information, the amount of information on a screen, the paging and scrolling of information, the position of a sought item within a list

    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.
