    Abstract
    Edited version of a report to the Australian Library and Information Association on the Conference on classification theory in the computer age, Albany, New York, 18-19 Nov 88, and on the meeting of the Dewey Editorial Policy Committee which preceded it. The focus of the Editorial Policy Committee Meeting lay in the following areas: browsing; potential for improved subject access; system design; potential conflict between shelf location and information retrieval; and users. At the Conference on classification theory in the computer age the following papers were presented: Applications of artificial intelligence to bibliographic classification, by Irene Travis; Automation and classification, By Elaine Svenonious; Subject classification and language processing for retrieval in large data bases, by Diana Scott; Implications for information processing, by Carol Mandel; and implications for information science education, by Richard Halsey.

    Abstract
    New forms of man-machine interaction are becoming available that have great power for the delivery of information. But the scales of speed and capacity on which the computing machines operate demand new thoughts as to how information can be stored and retrieved. The objective of the discussion in this paper is to argue for a combination of natural-language processing and subject classification to be able to meet the demands

    Abstract
    Three pre-web articles about using hypertext for knowledge representation. Duncan discusses how to use graphical, hypertext displays (she used Xerox PARC's NoteCards on a Xerox 1186 workstation) along with concept maps and facet analysis, a combination that would now be done with topic maps. The screen shots of her graphical displays are quite interesting. Her interest in facets is in how to use them to show things to different people in different ways, for example, so that experts can enter knowledge into a system in one way while novices can see it in another. Duncan found that facet labels (e.g. Process and Product) prompted the expert to think of related concepts when inputting data, and made navigation easier for users. Facets can be joined together, e.g. "Agents (causing) Process," leading to a "reasoning system." She is especially interested in how to show relstionships between two things: e.g., A causes B, A uses B, A occurs in B. This is an important question in facet theory, but probably not worth worrying about in a small online classification where the relations are fixed and obvious. These articles may be difficult to find, in which case the reader can find a nice sumary in the next article, by Ellis and Vasconcelos (2000). Anyone interested in tracing the history of facets and hypertext will, however, want to see the originals.

    Abstract
    In addition to using title keywords and subject headings for searching in the online catalog, the searcher may also use class numbers as access points. Library of Congress class or call numbers are particular effective in certain kinds of specific-item subject searching and serve as supplements to keywords and descriptors, improving precision and recall. Class number searching in the database can produce unique results because these numbers collect citations in ways that differ from those of keywords and descriptors

    Abstract
    Research leading to a detailed content analysis and profile of the Library of Congress Classification schedules. A description of the design, methodology, and preliminary findings of research in progress. Final results of the study are expected to aid the Library of Congress in the development of a MARC format for its classification schedules and in the conversion of the schedules into machine-readable form. LC's ultimate goal is the design of an integrated system which will permit on-line editing, maintenance, and control of the schedules, on-line classification and shelflisting procedures, the production of the schedules in two or more physical formats, and the use of LCC to enhance search capabilities in on-line catalogues.

    Abstract
    In the DDC Online Project, subject searching and browsing of DDC schedules and relative index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strenghts and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs.

    Abstract
    Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems
