    Abstract
    Analysis of research to date on improving subject access by including contents tables in bibliographic records. Results indicate the need for clear methodology (criteria for selecting notoces for enrichment, manual and semi automated methods, cost). Evaluations, based on recall, precision and rate of circulation, indicate manifest benefits, especially in virtual libraries where information is superabundant; but enrichment is a complex process

    Abstract
    Contents notes can improve online access to works containing essays, short stories, and significantly titles chapters. Few records in bibliographic utilities include contents notes. The OCLC PRISM service may provide an opportunity to cooperatively build a contents-enriched database. This paper discusses some issues related to the creation of enhanced records and their display in online cataloges. It also describes one library's efforts to add contents notes lically and to participate in an anticipated OCLC pilot project

    Abstract
    The paper examines the developmentss that have taken place during the last decade with respect to the provision of intellectual subject access in information databases storage. The principles of the SAP indexing methodology are outlined and exemplified, leading to a discussion of the consequences for the conception of the physical 'document' versus 'semantic entities' as the basic constructs for storage and multi-dimensional representation of subject matter. Finally, the paper analyzes the impact of very recent technologies which make achievable such access conceptions and mechanisms

    Abstract
    In 1986, all titles added to the collection at the Australian Defence Force Academy Library, are processed through their OPAC via a subject enhancement procedure (ESP). The procedure used for subject enhancement is based on the techniques developed by P.A. Atherton and B. Settel during the Subject Access Project at Syracuse Univ., 1977. Terms are selected from contents pages or the index of the book, depending on whether the terms are content bearing, and whether the terms refer to 5 or more pages of text. This results in the addition of an average of 73 words or 20 phrases to each MARC record. The terms are keyed into the MARC field 653 using in house modifications of the library's URICA system

    Abstract
    Contents enhancement of catalog records may increase access to books in collections and aid in effective resource sharing by providing more detailed descriptions about library holdings in the catalog. A sample of monographs in San Diego State Univ. Library was studied to determine the extent to which information in books from parts of the collection could be represented better by content notes, and to determine how much of this information has subject or analytical applications. The study revealed that approximately 23% of the books contain discrete content information not already represented in catalog records that could be added. Of those, 52% would be citation-based enhancements and 48% would be subject-based. Nearly 65% would require fewer than 25 enhancements, with an average of 8.03 enhancements per book for the total population

    Abstract
    Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures
