    Abstract
    Reports an investigation into the feasibility of usinf tutorials to train students to use on-line public access catalogues (OPACs). The library developed instructional software which conveys a conceptual model of an on-line catalogue and how it works. Reports the results of an experiment conducted to compare the effectiveness of the computer tutorial and the standard introductory classroom lecture on using the OPAC at the University of Toronto

    Abstract
    Uses the results of various user studies to offer some insight into user behaviour in connection with OPAC access points and to explore conditions for subject searching, the difficulties involved and the matching of queries to subject headings. Sums up suggestions for the improvement of subject access to OPACs

    Abstract
    Catalogue use studies in manual and online environments over the last 50 years have been succesful in identifying user behaviour and causes of user failure, but they have not led to substantial change in catalogue codes of practices. The online environment offers a myriad of new challenges

    Abstract
    Analyses the OPAC at the Australian Catholic University in New South Wales, Castle Hill Campus using an object oriented model following Rumbaugh's methodology, as described in 'Object oriented modelling and design, 1991'. The process of analysis, although difficult, is one of the most effective ways of determining each function of a system of this kind. The methodology is especially useful as the data structure, behavioural and functional aspects of the system are displayed in separate diagrams. This is an advantage for those analysing systems, who can display many factors without confusing different aspects involved in the analysis process

    Abstract
    Explores the variety of user behaviour exhibited by users of information retrieval systems over time and the effort of differences between expert and novice searchers on an understanding of information searching dynamics and on the design of information systems. Based on a naturalistic case study. Points out some of the dynamic patterns of behaviour of children's use of online catalogues (OPACs)

    Abstract
    Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

    Abstract
    This article first compares and contrasts the essential, fundamental differences between traditional and digital information mediums. It then reexamines the role of the online public access catalog (OPAC), refines the definition of library's catalog, and advocates the addition of Internet resources within the OPAC. Next, the article describes the building of the Alex Catalog, a catalog of Internet resources in the in the form of MARC records. Finally, this article outlines a process of integrating the futher inclusion of other Internet resources into OPACs as well as some of the obstacles such a process manifests.

    Abstract
    The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

    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
    Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

    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
    As part of a recent research project a large set of catalogue users' subject queries was collected by interview. The libraries and the data collection procedures are briefly described. The query set obtained has been divided into several general categories which illustrate the range of of types of subject search being performed. Each category of query is discussed, with a consideration of the problem which face the user in carrying out each type of search. Possible solutions to some of these problems are considered. The most important issue is the variation in specifity of the queries, whilst other issues relate to the users' expression of need, access to specific types of materials, interdisciplinary subjects, and inappropriate queries. These issues are summarised and the implications for OPAC design are discussed

    Abstract
    Rules regarding cataloguing, subject headings, the way information in bibliographic records is organised and the catalogue's interface, or the way the screen is set up, are barriers to the use of online catalogues by children Describes the background to and implementation of a project to create a child orientation catalogue with a graphical user interface, or one that relies on pictures instead of text, within Denver Public Library in Colorado. Now called the Kid's catalog and commercially available from the Colorado Alliance of Research Libraries Co., the catalogue's software acts as a front end to a library's regular catalogue

    Abstract
    One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

    Abstract
    A Serials Task Force at the University of California, USA, is currently working on merging the MELVYL catalogue and periodicals database. Details its design principles and discusses the major design issues of: name authority control, subject authority files, subsets, long searches, consolidation, sorting, and creation of possible new indexes for keywords, notes, titles, conferences, call numbers, combine author/titles, music, geospatial searching, and form limits
