    Abstract
    Two measures are examined that characterize the dispersion of a classification system when mapped to a second classification. One, a distance measure, captures the physical spread of a class when represented in the secon system; the second, from rank-frequency-analysis, characterizes the scatter of tokens over a set of types. The measures are tested by applying them to the library science portions of the LCC and the DDC using a database drawn from MARC records. Class mappings are presented that exemplify four extreme points of the two measures considered together: mappings where both measures score high, mappings where both score low, and mappings where one measure is high and the other is low. The conclusion is that the measures characterize two different properties of dispersion

    Abstract
    Menu selection systems reduce training and memorization, simplify entry of choices, and structure the user's task. However, the use of menu selection is no guarantee that novices or experts will be satisfied or able to carry out their work. This article focuses on the multiple design issues in creating successful menu selection systems. These include the primary issue of semantic organization and the host of secondary issues such as response time and display rates, shortcuts for frequent users, titles, phrasing of menu items, graphic layout, and selection mechanisms. Novel approaches such as popup menus and embedded menus are covered. Experimental results and design guidelines are presented

    Abstract
    It is intuitively clear that putting the cart before the horse is not the same as putting the horse before the cart. It is equally clear that a history of philosophy is different from a philosophy of history. Yet there is no logical relationship, like the AND/OR/NOT functions, which would enable manipulation of these permuted, non-commutative, relationships. In this paper we present a system for automatic handling of ordered sets, states based on these sets, and of differing points of view regarding a Universe of Discourse. We call what we are dealing with 'aspects' and we represent them by means of a new logical function called the 'overlap' function

    Abstract
    Project Jefferson was designed to help new students at the University of Southern California (USC) to acquire skills necessary for writing research papers through the example of research into ethical issues raised by the US Constitution. It runs on Macintosh Computers and is based on Apple Computer's HyperCard, a system wich allows users to browse different sources of information at their own pace and along their own routes while noting down useful discoveries in the notebook part of the system. Access to USC's locally mounted bibliographic data bases is also given without any tedious logging-on routines.

    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
    Exploring the advantages of a simulation (rather than expert systems) approach to designing a system to relieve reference desk overload. REFSIM can simulate a reference librarian, a teacher of reference librarians and a client, singly or in combination. It has an expert system consultation mode and several Intelligent Computer-Assisted Instruction (ICAI) modes. The components and architecture of REFSIM are described. Details, including a sample transaction, are given for the expert system mode, wich is to be used for consultation by library clients. An overview is supplied for 2 ICAI modes, wich can be used to instruct clients or train reference librarians.

    Abstract
    Paper presented at the 30th Annual Conference of the National Federation of Astracting and Information Services, Philadelphia, 28 Feb-2 Mar 88. In recent years, the amount and the variety of available machine-readable data, new technologies have been introduced, such as high density storage devices, and fancy graphic displays useful for information transformation and access. New approaches have also been considered for processing the stored data based on the construction of knowledge bases representing the contents and structure of the information, and the use of expert system techniques to control the user-system interactions. Provides a brief evaluation of the new information processing technologies, and of the software methods proposed for information manipulation.

    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
    Index Medicus, the abstract periodical published by the National Library of Medicine, could until recently only be consulted either in its printed version or on-line (Medline). Several versions of Medline on CD-ROM are now available, and the Biomedical Working Group of VOGIN (the Dutch Association of Users of Online Information Systems) has prepared this detailed comparison. Although CD-ROM is becoming more popular, many people are still unfamiliar with the new medium, and a number of authors have discussed the advantages and disadvantages of CD-ROM when compared with its on-line and printed equivalents.

    Abstract
    SIBRIS (Sandwich Interactive Browsing and Ranking Information System) is an interactive text retrieval system which has been developed to support the browsing of library and product files at Pfizer Central Research, Sandwich, UK. Once an initial ranking has been produced, the system will allow the user to select any document displayed on the screen at any point during the browse and to use that as the basis for another search. Facilities have been included to enable the user to keep track of the browse and to facilitate backtracking, thus allowing the user to move away from the original query to wander in and out of different areas of interest.

    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. Reviews the different roles of the AAT, the indexing guide, and the policy-making institution for which the indexing is done. Describes the AAT Subcommittee of the Research Libraries Group Art and Architecture Program Committee which was charged with developing indexing guidelines for the application of the AAT. The AAT Application Protocol was the result of the subcommittee's work and recommends a faceted arrangement for indexing terms as well as the use of natural language as a ready-made, rule-based system for retrieving headings.

    Abstract
    Describes the conceptual framework and a vocabulary which can be used to discuss strategies and choices involved in question handling. A model of question handling is presented which provides for: developing strategies for handling questions; evaluating the appropriateness of the strategy; and relating levels of service to resource requirements. The model involves 5 phases: conducting a reference interview; formulating a question handling strategy; handling the question; reporting the result to the client; and evaluating the service delivered. It describes the reference librarian's interaction with a client and the types of decisions which a librarian makes when selecting and matching the level of resources to the desired level of service.

    Abstract
    A controlled set of searches have been conducted by a group of searchers, at Manchester Polytechnic Library, on a trial subset of the British National Bibliography (BNB) data base on both CD-ROM and on-line. Various measures of search effectiveness and effiency were examined in relation to the effect of the differing user interface, including recall, precision, search time, user satisfaction and other more subjective factors. Discusses the potential for further research on the evaluation of CD-ROM.

    Abstract
    User performance on information retrieval systems is highly variable. After briefly reviewing the characterisitcs on which IR performance varies, reports on a specific study that sought to idetify both technical aptitudes and personality characteristics that were related to academic orientation variables previously found to predict IR performance. Academic orientation was related to technical aptitudes as measured by standardised achievement tests and coursework; and that academic orientation was related to some personaliyt characteristics, as measured by standardised tests. Since individual differences in information retrieval are assumed not to be random, argues that individual characteristics should be described so they can be accomodated through design and training

    Abstract
    In this paper we present the results of an experiment to help professional scientists and engineers undertake their own literature searches using a number of the major online bibliographic databases. The end-users, or experimental subjects, are already familiar with Deco, the text storage and retrieval system used by Unilever, but have little or no knowledge of the major online database systems, such as Orbit, Dialog, BRS, etc. The paper describes the design and development of a front-end system which simplifies the 'logon' procedure and converts Deco format commands into any of the other required languages. The users can thus search any of the major online databases just as if they were searching their own files on their local system ...
