    Abstract
    The rapid pace of OPAC implementation in this country is providing a fruitful environment for research, with a wide range of projects currently being undertaken, including a number concerned with the application of advanced information retrieval techniques to OPAC systems. This article reviews the current situation and describes some of the more important research projects being undertaken, particularly those funded by the British Library Research and Development Department. A brief description of the British Library's own OPAC project is also provided. The article concludes with an examination of the value of OPAC research and a look at where further research effort might best be concentrated

    Abstract
    Free text and controlled vocabulary searching can no longer be viewed as antagonistic techniques in information retrieval since they both display advantages and weaknesses dependent on a fairly wide range of context, with the option to use both increasingly favoured. An attempt is made to present a list of features associated with the two techniques and to suggest a methodology to assist in deciding on the optimal retrieval technique for a particular purpose. The relevance of the techniques in expert systems and full text contexts is also discussed. Finally, recommendations for further research are suggested, concentrating on survey techniques in real-life retrieval situations

    Abstract
    The Commision of the European Communities has commissioned a feasibility study for a European Register of Microform Masters (EROMM), the purpose of which is to investigate the desirability and feasability of a community-wide register, to propose possible methodologies of compilation, storage and dissemination and to make estimates of costs. The long-term objective of EROMM is to create a union list of records available in collaborating libraries throughout the countries of the European Community, but it is important to recognise that EROMM is a project for the creation of a data base, not for the creation of films or other surrogate media.

    Abstract
    The challenge facing the library profession is not only to learn how to identify information needs, but also to create new services and reshape existing service delivery patterns around them. Provides a brief examination of the literature of information needs and information seeking behaviour. Examines problems arising from meeting information needs in an electronic age, and describes a few societal changes that directly affect the way libraries attempt to meet information needs. Emphasises that the challenge of the 1990s is to design research that will help librarians and the information systems with which they work to anticipate a wide range of information needs.

    Abstract
    In this paper we identify the need for a new theory of information. An information model is developed which distinguishes between data, as directly observable facts, information, as structured collections of data, and knowledge as methods of using information. The model is intended to support a wide range of information systems. In the paper we develop the use of the model for a semantic information retrieval system using the concept of semantic categories. The likely benefits of this area discussed, though as yet no detailed evaluation has been conducted.

    Abstract
    This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end-users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

    Abstract
    Reference librarians, who are thoroughly familiar with the purpose, scope and arrangement of abstract periodicals, are uniquely qualified for the task of writing abstracts. The procedures described here offer a relatively simple way for them to write acceptable abstracts from the outset. Although research is being conducted in the area of machine generated abstracts, there wll continue to be a role for human abstractors.

    Abstract
    In this article we identify the need for a new theory of data, information, and knowledge. A model is developed that distinguishes between data as directly observable facts, information as structured collections of data, and knowledge as methods of using information. The model is intended to support a wide range of information systems. In the article we develop the use of the model for a semantic information retrieval system using the concept of semantic categories. The likely benefits of this are discussed, though as yet no detailed evaluation has been conducted

    Abstract
    The busy nature of a system designer's occupation often keeps him or her from reading professional material or attending conferences which might influence design strategies. This volume reports the proceedings of a national conference which examined influences on automated library system designers. The papers come from a wide variety of contributors, including librarians, library school faculty, library researchers, and commercial system suppliers. Tesions amongst the library's, vendor's, and user's perspectives on OPACs are evident, but revealing

    Abstract
    Community information systems originated with the field of social services but was soon adapted by public libraries in the 60s. Because it is a recent development in library services, there have been a wide range of interpretations as public libraries have attempted to incorporate these services into the more traditional library services. Presents a selective overview of the history of community information services and a review of current developments in the field.

    Abstract
    Es wird versucht zu zeigen, daß die ursprüngliche Funktionen der Bibliotheken und Dokumentationsstellen, Informationen zu sammeln, zu ordnen und vefügbar zu machen, Konstanten in einer sich ändernden Welt sind. Verbundkatalogisierung, Logistik beim Angebot der verschiedenen Informationen und Informationsmanagement sind neue Möglichkeiten für alte Problemstellungen. Hilfsmittel wie CD-ROM, Image Recognition Reader, Terminals für Onlinezugriffe, Expertensysteme, Mailboxen, Local- und Wide-Area-Networks ebenso wie beispielsweise roboterartige Lagerverwaltungsmaschinen sind sehr brauchbar, um diese klassischen Aufgaben zu bewältigen, Bibliotheken haben drei Hauptaspekte: Sie erfüllen eine archivarische, eine ökonomische und eine synoptische Funktion. Das Ziel der vorliegenden Arbeit ist, in einer Zeit technologischen Umbruchs an die Grundlagen bibliothekarischer Existenz zu erinnern. Bibliothekare, Dokumentare und Archivare müssen sich über die Bedeutung der sog. Electronic Library klar werden. Es ist für unseren Berufsstand eine fundamentale Entscheidung, diesem mutigen Schritt in die Zukunft zu wagen

    Abstract
    89 articles from a small, Danish left-wing newspaper were indexed by PRECIS and KWIC. The articles cover a wide range of social science subjects. Controlled test searches in both indexes were carried out by 20 students of library science. The results obtained from this small-scale retrieval test were evaluated by a chi-square test. The PRECIS index led to more correct answers and fewer wrong answers than the KWIC index, i.e. it had both better recall and greater precision. Furthermore, the students were more confident in their judgement of the relevance of retrieved articles in the PRECIS index than in the KWIC index; and they generally favoured the PRECIS index in the subjective judgement they were asked to make

    Abstract
    The delivery of library reference service can be practically supplemented through the appropriate incorporation and use of software tools commonly reffered to an expert system. The level of support such systems can affort the reference service organisation is dependent on the degree of complexity characteristic of the rule-based programming techniques used to develop a particular system and the size of its knowledge data base. Since most expert systems are designed to simulate the process of problem-solving practiced by an expert in a given field, an expert system designed to fully emulate library reference work must have the potential to respond to a wide subject range of questions with varying degrees of response adequacy. Describes a microcomputer-based reference expert-type system.

    Abstract
    Report of a study comparing 2 methods of indexing: LEXINET, a computerised system for indexing titles and summaries only; and manual indexing of full texts, using the thesaurus developed by French Electricity (EDF). Both systems were applied to a collection of approximately 2.000 documents on artifical intelligence from the EDF data base. The results were then analysed to compare quantitative performance (number and range of terms) and qualitative performance (ambiguity of terms, specificity, variability, consistency). Overall, neither system proved ideal: LEXINET was deficient as regards lack of accessibility and excessive ambiguity; while the manual system gave rise to an over-wide variation of terms. The ideal system would appear to be a combination of automatic and manual systems, on the evidence produced here.

    Abstract
    An essential part of information retrieval knowledge is the knowledge of data base contents and structures. Currently, the variety of data bases is so wide that it is difficult to know the contents and structure of a particular data base and how they differ from those of other data bases. Because of the lack of commonly acknowledged guidelines for data base descriptions, each on-line service designs and produces printed manuals, on-line help texts and other user documentation in its own manner. For the presentation of exact information and knowledge on a data base, common, structured principles for data base descriptions are needed. Requirements and some solutions for such description principles are presented.
