    Abstract
    Shortened and revised version of a paper presented during an Education Librarian's Group session at the Under One Umbrella Two Conference, organized by the Library Association in Manchester, 9-11 Jul 93. With the possibility of free text searching and easy access to CD-ROM databases, users often do not realise that subject searching is enhanced by familiarity with the controlled vocabulary underlying the indexing system of the database. Discusses the construction of information retrieval thesauri, the problems of terminology and how the use of thesauri can make searching more effective, using education thesauri as examples

    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

    Abstract
    Reports results of research into the feasibility of using OCR scanner technology to capture contents pages of collective monographs and to extract the bibliographic information of each individual work and process this using a standardized language, such as SGML, for tagging electronic documents. By this means, data can be used as electronic information or stored in OPACs, thus providing additional access points. Outlines a pilot system to test the initial hypotheses, show the feasibility of achieving the suggested goals and develop the tasks required for them to be carried out as automatically as possible

    Abstract
    Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others

    Abstract
    Myriad new information resources are available to contemporary library users. While print remains the foundation of most collections, libraries are also beginning to provide access to an array of bibliographic, numeric, and full-text databases. As more and more information is produced in electronic form and presented at computer workstations, the library catalog is being given an expanded role. The expanded catalog will play a crucial part in organizing information in electronic libraries, and in providing navigational assistance to library users. Like the traditional card catalog, the expanded catalog will not only lead to specific items or groups of sources, but also will provide connections to related materials. These connections will uses standard data elements to link the results of a search in one database with related material in another. For example, links will show local library holdings of sources in citation databases. Cornell University's Mann Library serves the College of Agriculture and Life Sciences, the College of Human Ecology, and the Division of Biological Sciences. As part of electronic library development, Mann staff have been analyzing issues involved in making it possible for Agricola and BIOSIS users to see, automatically, which of their retrieved citations are from sources available in the Cornell libraries. Samples of citations from Agricola and BIOSIS were drawn, and data elements present in these records were compared with bibliographic records of the library's holdings. In some cases, links would be provided by ISSNs. The study shows, however, that the presence of standard identifiers such as ISSN, USBN, or CODEN cannot be assumed, and other linking algorithms must be developed. This article presents study results, provides an overview of several linking systems, and identifies some of the difficulties caused by lack of standardization between different bibliographic databases. It is clear that the concept of an expanded catalog will require not only links between information resources but agreements among information professionals on standard data elements.

    Abstract
    To enhance descriptions, cataloguers can add 'enriching' words or phrases to titles, or introduce content-enriched access features to aid subject-based research. Additional and natural language subject headings designed to support, though not replace, controlled language headings can result in enhanced indexing. Analytical cataloguing and double indexing are 2 other means by which readers can gian access to additional bibliographic data. Also examines how online research tool effectiveness can be enhanced by a system of automatic links between descriptors

    Abstract
    Since Dec 86, the Australian Defence Force Academy (ADFA) library has been enriching bibliographic records by adding terms from either the contents pages or indexes of books. 40.000 records are now enriched, representing about 25% coverage of the ADFA database of 210.000 titles. Evaluates the retrieval effectiveness of the enriched data in an OPAC, in comparison with title and LCSH, using 90 topics from 6 different subject areas

    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
    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
    As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology
