    Abstract
    Research conducted in the early 80's has shown that subject access is still one of the most dominant approaches in OPACs. However, while some of the subject searches result in no recall, others often retrieve so much that users are discouraged to proceed further. These and other problems were investigated and solutions were found in improving search methods (such as word stemming, extending search to full bibliographical record and providing end user thesaurus) and indexing techniques (such as ny enhancing subject headings with table of contents and back of the book indexes or by traditional systems). More recent research indicates that the real answer to the question of 'precision without sacrificing recall' lies in the developing 'user friendly novel interfaces' and also in designing 'knowledge based systems', wherein sers would not be expected to learn query formulation or even to be familiar with the indexing language of the system. Several interesting studies and research projects on the subject have produced a whole gamut of information, but one can still visualise the evolving trends of research vis-a-vis their future prospects as possible solutions

    Abstract
    Study was undertaken by Information Systems Consultants, Inc., Washington DC, to determine the current state of online patron access catalogues, with emphasis on the degree to which access has been extended beyond that available in card, microform, and early patron access online catalogues. The methodology used was similar to that used in an earlier report. All of the library automation vendors of both multi user systems and micro based systems were sent a copy of the latest version of the catalogue portion of the model RFP (request for proposal) for an integrated online library system which was developed for the study described in the last reference. The vendors were asked to respond as if it had been sent by a potential library customer. A matrix with the raw data is presented for both multi user systems and micro based systems along with the RFP. A brief description of each vendor is followed by a tabulation of the RFP responses and concluding comments by the author

    Abstract
    Describes the technical aspects of a feasibility study to test a new concept in bibliographic control based on the manifestations of a work. Conventional catalogues are based on the main entry principle which follows from the concept that there should be 1 main entry for each work. The Bradford OPAC project, at Bradford University, UK, aimed to develop a new type of hierarchical bibliographic record structure to cope with the problem of applying the main entry principle to multiple cataloguing records which are manisfestations of the same work. The project involved the storage of MARC data sets of bibliographic records, taken from the Bradford University Library OPAC and the OCLC WorldCat database, in a relational database (MS Access) on a PC. This was then used for an experimental Windows based OPAC, to evaluate the overall success of the idea and any problem areas identified with a view to a more substantial study. The project also aimed to test whether intelligent and responsive software, using a graphic user interface and based on sets of manifestations, could provide a better route to information than a display based on a single work

    Abstract
    COPAC (CURL Online Public Access Catalogue) grew out of the union catalogue database of the Consortium of University Research Libraries (CURL). COPAC provides free access to the information contained in the main online catalogues of a number of important UK academic research libraries. Records are currently contributed by the university libraries of Cambridge, Glasgow, Edinburgh, Leeds, Oxford and Trinity College, Dublin (all members of CURL). COPAC evolved from the recommendations of the Follett Reports and is seen as the 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. COPAC may be accessed, free of charge and 24 hours a day as a WWW interface or as a text interface

    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
    Reports results of a questionnaire survey of the user characteristics of Korean student user groups in searching OPACs. The study examined the use of 5 selected OPAC systems in 5 academic libraries in the Austin, Texas and North Texas areas. The objective was to provide information on the characteristics of a specific group of international college students from a developing country in order to assist system managers in the selection of OPAC systems. The major conclusions of this study were: the academic level and age of students affect the preference towards an OPAC, but academic major of the students does not affect the preference; system designers should prepare more specific instructions regarding searching methods; there is a negative relationship between the number of searching methods that the respondents knew in using OPACs and the frequency of manual card catalogue use; and menu driven systems should be the first selection of OPAC systems for Korean students. Proposes recommendations for the design, adoption, or management of a new OPAC system
