    Abstract
    Reports an investigation to compare the various forms of catalogue available in Liverpool City Libraries and Liverpool John Moores University Library. The information was gathered through interviews with 52 lecturers and students at Liverpool John Moores university. The interview questions were concerned with the use of the library catalogues which were available, the effects of the online public access catalogue (OPAC) on searches, the effects of previous experience of an OPAC and catalogue preference. Nearly all the library users interviewed had used the OPAC. Many of them had changed the way in which they searched for references. The majority preferred the OPAC and did not continue to use the microfiche catalogue

    Abstract
    The UK's National Art Library at the Victoria & Albert Museum joined the Online Computer Library Center (OCLC) in 1986 and from 1987 to 1990 created catalogue records in MARC format on the OCLC database pending the introduction of a stand-alone computer system. the library now employs a Dynix microcomputer system for cataloguing, acquisitions, circulation, serials control, community information and the provision of online public access catalogues (OPAC). Describes library records currently available online, progress in retrospective conversion, internal networking and plans for external networking via the Joint Academic Network (JANET), and the provision of bibliographic and image databases in CD-ROM and videodisc format. Future developments will include interface between museum/image and library/documentation databases

    Abstract
    Examines 3 aspects of keyword searching to see if defaulting to keyword searches might serve as a solution to the problems users find when performing subject searches in OPACs. Investigates if keyword searching produces useful results; if people who use keyword searches to find information on a subject report that they are satisfied with the results; and how keyword searching and controlled vocabulary searching are offered and explained in currently available OPAC interfaces. Concludes that both keyword and controlled vocabulary searching ought to be easily available in an OPAC, and that improvements need to be made in explanation and help offered to subject searchers

    Abstract
    User persistence in displaying postings is a significant human factor in the design of computer driven information systems, including online catalogs. Expert opinion and a study of users of a first generation online catalogue have suggested that users normally display no more than 30 to 35 postings. A follow up study on a second generation system with a larger database found that a greater proportion of users reported overload, but 100 postings (rather than 15) were considered 'too many'. Partially persistent users typically displayed 28 postings, but overloaded uses did not outnumber totally persistent users until postings retrieved exceeded 200. The findings suggest that, given sufficient resources, designers should still consider 30 to 35 postings typical persistence, but also justify treating 100 or 200 postings as a common threshold of overload

    Abstract
    Reports briefly on the development, by the Consortium of University Research Libraries (CURL) of the CURL OPAC, or COPAC. COPAC is seen as the partial realization of the aims of earlier projects, such as the UK Libraries Database System (UKLDS). Although COPAC was not designed as a union catalogue, it was a natural next step for CURL to obtain funding from the Joint Information Services Committee (JISC), following the Follett Report, to use the database to create a union catalogue. The work is being undertaken at Manchester University, which has held the CURL database since its creation, and the version was launched on 30 Apr 96

    Abstract
    Reports results of a questionnaire survey of lecturers and students, at Florida University at Gainesville, to determine the degree to which the information provided in catalogue records serve the needs of library users and the usefulness of including and displaying typical elements of catalogue records. Results indicate the highest level of agreement with usefulness of: title; primary author; date; subjects; other authors; and series. There were moderately high levels of agreement for: summary notes; contents notes; standard numbers; publisher; pagination; and related titles; and lower levels of agreement for reference notes; place of publication; index notes; illustrations; and size

    Abstract
    COPAC (CURL Online Public Access Catalogue) is the new OPAC which provides free access to the information contained in the main online catalogues of a number of important academic research libraries. Records are currently contributed by the university libraries of Cambridge, Glasgow, Edinburgh, Leeds, Oxford and Trinity College, Dublin. All libraries are members of the Consortium of University Research Libraries (CURL) and COPAC is seen as partial realization of the aims of earlier projects, such as the UK Libraries Database System (UKLDS). Records from the Imperial College of Science, Technology and Medicine, and London University (Senate House) are being loaded and the online catalogues of the remaining 12 CURL member libraries will be added in due course

    Abstract
    Reports results of a study to elicit information from the users of the Wisconsin University at Madison online catalogue (Network Library System (NLS)). The General Library System (GLS) conducted focus group interviews with undergraduate students, graduate students, and faculty. Undergraduate students tend to utilize subject searching capabilities. Graduate students and faculty utilize subject searching only as a last resort; they typically search by known author or title. A significant number of the participants reported experience with library online catalogues other than NLS, although the majority of faculty reported very little experience with other online catalogues. All the focus group participants, but particularly the undergraduate students, evidenced confusion between keyword searching and searching controlled vocabulary. Inclusion of circulation status in the bibliographic records was identified as an important feature of the catalogue

    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
    Surveys the status of catalguing practice in university libraries in 3 Asian developing countries, Pakistan, Malaysia, and Saudia Arabia. Examines the extent of the usage of international cataloguing tools such as cataloguing codes (AACR, ISBD), classification schemes (DDC, LCC) and subject heading lists (Sears, LCSH). Results indicate that there is an overall uniformity in the use of such tools, with a trend towards automation of cataloguing services with more access points for catalogue searching. Online catalogues are also replacing all traditional catalogue forms (card, printed, and microform). Findings show that, in using information technology in technical services, Malaysian university libraries are more advanced than those of Pakistan and Saudi Arabia

    Abstract
    Looks at ways of making library catalogues easier for children to use, including the Book House, a Danish search system based on studies of how library users carry out searches in the catalogues. This and other research shows that much can be done to make library catalogues easier for children to use and to encourage the search for information andreading. In this work libraries must start from the subjects children ask about and adapt to children's level of development and ways of expressing themselves
