    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
    Key problems of subject searches in online public access catalogs are that too much may be retrieved and that the display may be arranged in what appears to be an unintuitive and unhelpful manner. A study was undertaken on one large database to determine how often the display of a subject and its modifications and subdivisions extended over more than two screens and what the results on display would be of compressing geographic subdivisions and other modifications. The study then addressed the question of how often the display of a term and its subdivisions was interrupted by the appearance in the display of inverted headings, phrase headings, and headings with parenthetical qualifiers

    Abstract
    This short guide is intended to help librarians and OPAC system designers to make decisions about the design of displays of more than one subject heading. The authors stress that they offer guidance rather than standards or prescriptions; their clear prose is cautious and even the number of recommendations is limited. A 12-page introduction contrasts the "structural approach" and "strict alphabetical approach" to filing, showing examples and stating arguments for each. 7 chapters cover display of subdivisions, inverted headings, display of qualified headings, arrangement of numerical headings, display of subjects interfiled with names and titles, punctuation and messages to the user. Within each chapter, questions involving choices between two or more approaches are followed by brief statements of current practice (LC rules, ALA rules, and systems in existing OPACs) extensive examples demonstrating such choices, and arguments for and against each. The authors warn against ever assuming that the user knows the needed subject headings, and acknowledge that the best OPAC design often depends on the setting and on the user's understanding of the system. Although the topic may be beyond the purview of the authoring committee, the discussion here makes one yearn for interactive OPACs that can analyze the user's needs and provide appropriate guidance to whatever system is adopted

    Abstract
    This paper recognizes the limitations of the existing file of Library of Congress authority records for subject heading assignment and validation. It makes recommendations for a new machine-readable file of authority records for topical subdivisions and for enhancements to the existing subject authority file. The recommended changes qould enable online systems to assist in subject heading formulation and verify, with limited assistance by human intermediaries, the individual components of subdivided headings. A study of subdivided subject headings in a large bibliographic database forms the basis of the recommendations

    Abstract
    Amstelveen Public Library in the Netherlands introduced the online Kid's Catalog in 1997 to enable young users to access the library's catalogue. The system was developed in the United States and has been translated into Dutch for use in Amstelveen. The system enables users to access the catalogue through a menu of icons or by typing in author, title and subject headings. The system can recognise typing errors and offer corrected headings. The system is extremely popular both with children and adults

    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 need for subject access on OPACs has been widely recognised since early development in the USA. Many OPACs in UK academic libraries provide subject access to catalogue records, mostly through search strategies such as keyword access or subject headings searches. However, users do find subject searching more difficult than known-item searching so most OPAC systems provide help screens to assist users in their searches

    Abstract
    Current OPAC show their weakness in terms of ease of use and comprehension of user requests, and more generally in man/machine dialogue. Most OPAC searches are for subjects and these give the word results. Natural language processing techniques exist to reduce these difficulties. In France, natural language processing has been used to access the yellow pages (headings) of the French phone directory and the telematics services directory; examples are included. No doubt the future library systems will use these techniques to make the new OPACs really open, public, accessible and co-operative (user-friendly)

    Abstract
    Outlines the difficulties experienced by users in the searching of OPACs. Describes visits to 3 scientific libraries in Montreal which provide OPACs: the library of the Ecole Polytechnique which offers ARCHIMEDE; the scientific library of the University of Quebec which offers BADADUQ; and the Physical Sciences and Engineering Library of McGill University which offers MUSE. Compares user training programmes offered by each of these libraries and discusses the librarians' responses to a questionnaire on user training under the following headings: mode of learning; teacher participation; marketing policy; and statistics of OPAC usage

    Abstract
    A survey of catalogue use in 1993 at Utrecht University in the Netherlands showed considerable dissatisfaction with the online catalogue's subject search facilities. Of those who used subject searching 64% preferred subject headings against only 2% who chose classification schedules. Library users make little use of the existing facilities for assistance and leaflets which are available in the library. It has, therefore, been decided to provide a programme of instruction in library use and to move towards a unified system of subject access to the library's catalogue

    Abstract
    A study of the online catalogues of major academic libraries and databases in the Netherlands shows considerable variation in the form of name used for the author W.F. Hermans. The problem lies with a lack of authority control in headings used in the Dutch national union Pica catalogue. Reactions from 2 cataloguers point to the difficulties in maintaining catalogues in the face of reduced funding and to the important role played by the Pica project in improving library services and reducing cataloguing backlogs

    Abstract
    User interfaces for CD-ROM products in the academic library environment must accomodate a variety of user and task profiles. Discusses the practical considerations that govern the implementation of interface design principles for such electronic data bases under the following headings: redesign goals; interaction style; menu design and implementation; system structure and the search paradigm; basic system operation and screen layout; simplified features; integrated novice and expert mode; redesign constraints; and hardware and software constraints

    Abstract
    Description of an attempt to improve OPAC subject access at Kobe University Library using Nippon Decimal Classification, 8th ed. (NDC8). Examines the theoretical aspects of using a classification for subject searching, then explains the Kobe system. Using the NDC8 machine-readable data file, a database was created for the OPAC, incorporating class numbers and subject headings. Difficulties arise from subdivisions and the structure of NDC8 itself, but it is an important area for development
