    Abstract
    Compares and evaluates the functional capabilities and interface characteristics of OPACs from the user oriented perspective, using a systematic framework. OPACs of OhioLINK and its 16 member libraries are the object of the investigation. The interfaces used 6 system software but showed a variety of features in access to OPACs, operational control, access points, search formulation control, and user assistance. Interface design alternatives are identified and qualitatively analyzed

    Abstract
    Adapted from a paper delivered at the Art Libraries Society of North America Annual Conference, Jan.93. In many libraries the OPAC has become the multifile OPAC, a new environment with greatly expanded access options and increased complexity of access procedures. Describes a strategy devised by the University of Nevada, Las vegas Library, for developing an instruction programme in the multifile OPAC environment in a systematic manageable ways. Discusses the 4 areas which emerged as basic to an instruction programme for multifile OPACs: selection criteria for the various databases; access procedures; approaches useful in searching new systems; and search concepts relevant across databases

    Abstract
    Conceptual considerations on possible synergies between hypertext and indexing languages' research. The existence of a common conceptual and theoretical background encourages and facilitates cooperation. It is concluded that the conjunction of the almost biological flexibility of the hypertext and the logical and conceptual consistency of indexing languages is a promise of better and more effective information management systems in the future

    Abstract
    Examines the advantages and disadvantages of precoordinated, postcoordinated and automatic indexing with regard to existing information storage systems, such as card catalogues, OPACs, CR-ROM databases, and online databases. Presents a general model of document content representation and concludes that the library profession needs to address the development of databank design models, relevance feedback methods and automatic indexing assessment methods, to make indexing more effective

    Abstract
    The study of subject access to UK academic library catalogues was based on a questionnaires end out during Summer 1991. 86 out of a possible 110 questionnaires were returned. All universities and polytechniques now have OPACs which are progressing well towards comprehensive bibliographical coverage of their libraries' stocks. The MARC format is now widely used. Subject access strategies are usually based on either Library of Congress Subject Headings or inhouse indexing systems but almost half the OPACs studies have no separate subject searching option based on subject indexing is expensive and future subject indexing strategies are best based on pre-existing controlled vocabularies. Strategies authority control is essential. A limited range of software strategies is recommended including the need to limit search results

    Abstract
    Argues that in library cataloguing and for optional functionality of bibliographic records the indexing of fields and subfields should follow a uniform approach. This would maintain effectiveness in searching, retrieval and display of bibliographic information both within systems and between systems. However, a review of different postings to the AUTOCAT and USMARC discussion lists indicates that the indexing and tagging of cataloguing data do not, at present, follow a consistent approach in online library systems. If the rationale of cataloguing principles is to bring uniformity in bibliographic description and effectiveness in access, they should also address the question of uniform approaches to the indexing of cataloguing data. In this context and in terms of the identification and handling of data elements, cataloguing standards (codes, MARC formats and the Z39.50 standard) should be brought closer, in that they should provide guidelines for the designation of data elements for machine readable records

    Abstract
    Online public access catalogues enable users to undertake subject searching by classification schedules, natural language, or controlled language terminology. In practice the 1st method is little used. Controlled language systems require indexers to index specifically and consistently. A comparative survey was made of indexing practices at Amsterdam and Mijmegen university libraries. On average Amsterdam assigned each document 3.5 index terms against 1.8 at Nijmegen. This discrepancy in indexing policy is the result of long-standing practices in each institution. Nijmegen has failed to utilise the advantages offered by online cataloges

    Abstract
    Describes the problems caused by the growth of bibliographic databases. Major problems are caused by seacrh systems based on Boolean operations because of the slowness, broad indexing and user difficulties due to present user links and search systems. Some suggested solutions are: use of combined search algorithms, more specific indexing, thesauri and improved user links

    Abstract
    The media centre at the City of Science and Industry, Paris, bases cataloguing practices on user habits, simulating searches which users have done to identify how access can be improved. In relation to the audiovisual viewer, which offers a selection of 3.500 films, this has led to including summaries and closer indexing, so that items can be retrieved by subject, not just by title as in the general catalogue. Economy of indexing can be justified as long as there is more information available from another resource. Analysis of failed searches has shown that wider subject indexing and integration of subject research and keywords would reduce noise. In the same way that physical layout and presentation of collections can help users, so should catalogue structure and organisation

    Abstract
    Decribes the BookHouse, a system for the retrieval and indexing of fiction and non fiction literature developed for public and school libraries though cooperation between library and information science professionals. Discusses 3 aspects of the system: domain characteristic; task analysis; and user characteristics. Outlines the framework underlying the collection of field data with special emphasis on the work involved in transforming the empirical field studies of user behaviour in the library into computer system specifications and subsequent design of a retrieval system providing subject access to fiction. Describes a few of the many indexing policies, rules and practices which evolved for concept identification and book descriptions as well as the functionality and associated displays of the system for supporting the retrieval and indexing of fiction
