    Abstract
    The growing interest in end user or direct patron access to on-line bibliographic databases is reviewed with references to online catalogues, databases, and CD-ROMs. The literature of end user searching is surveyed with notes on: user training, software search aids, end user services in libraries: characterisation of end user searches; the role of librarians; and CD-ROMs as end user media

    Abstract
    Problems in determining output size are sometimes associated with the performance of online bibliographic searches for clients in academic and other libraries. These problems are examined through discussion of a fallacy in thinking that arises when searchers try to produce the "perfect thirty-item" online search. Origins of the fallacy are explored by considering sources of misunderstandings between client and searcher and by identifying differences between manual and online searching. Several types of online searches are distinguished, and search techniques that avoid the fallacy are recommended for each search type

    Abstract
    The authors have studied the transaction counts from two and one-half years activity at the public use terminals of the Ohio State University Libraries' prototype online card catalog to determine what search options academic library patrons use the most often and whether this pattern varies from that reported in major catalog use studies. The preliminary findings indicate significant differences in search strategy that may result from a unique user group that prefers to search the online catalog, more useful searches in the online system, or special search patterns imposed by the computer hardware itself. Both the different searches used by patrons and why they choose them should be important factors in the design of future online catalogs

    Abstract
    Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved

    Abstract
    Describes the function and problems of the traditional card catalogue compared with a computerised catalogue. Examines library cataloguing with the computer, linked to rules for subject cataloguing, as well as the oppor-tunities offered by computerised title entries, the transfer of data from outside, data base structure and indexing. Also looks at techniques for searching catalogues with computers, including search rules with Boolean operators, searches restricted to specific fields of free search in all fields for a vague concept. Other topics cover the essential principles of the OPAC, its information functions, mail box function and hardware configuration.

    Abstract
    Browsing refers to information retrieval where the initial search criteris are generally quite vague. The fundamentals of browsing are explored as a basis for the creation of an intelligent computer system to assist with the retrieval of online information. Browsing actions via a computer terminal are examined, together with new methods of accessing text and satisfying user queries. Initial tests with a prototype system illustrated the use of different retrieval strategies when accessing online information of varying structure. The results suggest the construction of a more intelligent processing component to provide expanded capabiblities for content extrction and navigation within text documents

    Abstract
    A browsable display under a specific search term can often frustrate users if the display is carried over several screens. This article investigates methods of compressing headings identified by MARC subfield codes to reduce the size of browsable displays. Arguments are presented that a more efficient system design can be achieved by machine sorting of subdivisions via a conceptual, rather than alphabetical, approach. The author concludes that system architecture for browsable subject index displays must be redesigned to relieve the user of the burden of data organization

    Abstract
    Weaknesses within the system of LCSH are widely expected to be bypassed by OPACs as they open other subject access routes into collections. How LCSH perform under OPAC retrieval capabilities in direct comparison to title field subject searching is studies heuristically and quantitatively. Observed patterns of LCSH function are discussed, and conclusions about search strategy are offered

    Abstract
    As librarians evaluate the capabilities of online catalogs they will need to consider what information users expect to find in the catalog and what characteristics of the catalog will help users in their search for this information. The findings of studies concerning how library users actually use card catalogs and online catalogs, and their successes and failures in that use, can be used to determine the capabilities that are needed in anonline catalog to satisfy the bibliographic requests of library users

    Abstract
    In Febr. 1989, Vanderbilt University Library introduced a locally mounte MEDLINE file into its NOTIS-based online catalog. Planning and programming efforts are under way to add several H.W. Wilson databases by summer 1989. Considerations related to decisions about databases and search engine selection are described; key factors in the implementation process are presented

    Abstract
    One of the basic information-seeking activities where library users might experience information overload is scanning lists of references. Because much information seeking is discretionary - users may abandon a search without fear of penalty - lists that are too long may influence users to stop searching

    Abstract
    Presents the results of research carried out to discover whether or not the ability to search an online catalogue using keywords is a reasonably alternative to a built-in cross reference structure for variant forms. MARC records were checked against LoC authorities for references from non-preferred headings. All keywords in these references were then compared, and matched, when possible, with keywords in any MARC fields

    Abstract
    In 1987 the Austrian National Library and the University Libraries began to implement the Online Library Network System BIBOS which will offer also an on-line public access catalogue (OPAC). After discussing the basic design of the forthcoming OPAC, requirements of its features (access, search functions, output, interface to circulation control) are formulated.
