    Abstract
    Report of a survey 96 (out of 119) US and Canadian member libraries of the Association of Research Libraries (ARL) to determine their use of on-line and CD-ROM data bases, including OPACs. 4 catalogues were identified: on-line mediated searching (97%); CD-ROMs (96%); end-user on-line searching (45%); and locally mounted magnetic tapes (37,5%). The latter option is expected to be the most widely used option in the new future. Although CD-ROM caused some migration from on-line, most migration was from printed sources to CD-ROM. Tables show: on-line hosts most used for intermediary on-line searching; on-line data bases most after searched by intermediaries; end user on-line systems offered by most libraries; the 20 most popular CD-ROM data bases; and the 8 magnetic tape data bases accessible on OPACs

    Abstract
    Reports the findings of an experiment designed to compare on-line data bases and equivalent printed versions in 1 area of reference services, the answering of ready reference questions. 68 reference librarians searched for answers to the same set of 12 questions using either print or on-line sources. Details of the questions are given. In the case of conceptual questions on-line proved faster than print, particularly for 2-concept questions, and the increased speed was not at the expense of accuracy. In the case of factual questions, print sources proved to be considerably faster than on-line. Suggests 2 guidelines: when bibliographic information is available in both print and on-line formats, on-line should be the tool of choice, particularly for multi-concept questions; simple factul questions can be answered more quickly using printed sources.

    Abstract
    Reports an investigation into the feasibility of usinf tutorials to train students to use on-line public access catalogues (OPACs). The library developed instructional software which conveys a conceptual model of an on-line catalogue and how it works. Reports the results of an experiment conducted to compare the effectiveness of the computer tutorial and the standard introductory classroom lecture on using the OPAC at the University of Toronto

    Abstract
    TOSCANA is a computer program which allows an online interaction with larger data bases to analyse and explore data conceptually. It uses labelled line diagrams of concept lattices to communicate knowledge coded in given data. The basic problem to create online presentations of concept lattices is solved by composing prepared diagrams to nested line diagrams. A larger number of applications in different areas have already shown that TOSCANA is a useful tool for many purposes

    Argues that geographic access in on-line catalogues could be improved by organising and structuring geographic data through the hierarchies of a thesaurus. The proposed thesaurus, based on geographic area codes and the DDC area tables, would incorporate geographic coordinate data, and would allow catalogue users to expand or refine a search by defined ares

    Abstract
    The PRO-CITE and BIBLIO-LINK software packages make the process of compiling bibliographies and internal data bases much easier than when all the steps in the process were manual (compiling, typing). The 2 programs work on records that have been downloaded from on-line data bases. BIBLIO-LINK analyses the downloaded records to determine document type and stores the data in the appropriate PRO-CITE workform, putting fields from the downloaded record into the correct PRO-CITE fields.

    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

    Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.

    Abstract
    With formal concept analysis surveys are analyzable in the way that a meaningful picture of the answers of the interviewed persons is available. Line diagrams of large concept lattices might become less readable up to the point that it is impossible to pursue the line segments with the eyes. Nested line diagrams give the opportunity to overcome these difficulties. The main idea of nested line diagrams is to partition the line diagram into boxes so that line segments between two boxes are all parallel and may be replaced by one line segment. The possibility to draw line diagrams with more than two factors does allow it to describe concept lattices with many hundred or thousand concepts in a clear structure. In practice it has often been proven useful to take standardized scales for the single levels

    Abstract
    Paper presented at a symposium on 'Implementing the Art and Architecture Thesaurus (AAT): Controlled Vocabulary in the Extended MARC format', held at the 1989 Annual Conference of the Art Libraries Society of North America. The only way to get bibliographic records on to campus on-line library catalogues, and slide records on the national bibliographic utilities, is through the use of MARC. Discusses the importance of having individual slide and photograph records on the national bibliographic utilities, and considers the obstacles which currently make this difficult. Discusses mapping to MARC from data base management systems.

    Abstract
    A known-item search for abstracts to previously retrieved references revealed that 2 documents from the same annual volume had been indexed twice. Working from the premise that the whole volume may have been double-indexed, a search strategy was devised that limited the journal code to the year in question. 57 references were retrieved, comprising 28 pairs of duplicates plus a citation for the whole volume. Author, title, source and descriptors were requested off-line and the citations were paired with their duplicates. The 4 categories of descriptors-major descriptors, minor descriptors, subheadings and check-tags-were compared for depth and consistency of indexing and lessons that might be learnt from the study are discussed.
