    Abstract
    In online retrieval search results do not always match the intent in spite of using correct keywords (descriptors). One of the causes of this problem is found in the hierarchical structures of the thesaurus, which often contains relations between broader and narrower concepts, the opposite of which is not necessarily true. Some examples are described from 2 thesauri, MeSH and JICST. In these cases searchers need to make an effort to increase precision

    Rez. in: Canadian library journal 49(1992) S.166 (P. Nicholls): "Basically a collection of the proceedings of a program given at the ALA's 1987 annual conference, the original impetus for the session was to familarize bibliographic utilities, library systems staff, and integrated library system vendors with the recently-released machine-readable LCSH-mr so that they could "integrate this new tool into online bibliographic systems to provide the cataloging, thesaurus maintenance, file maintenance, and retrieval functions associated with subject authority work." These papers were writeen in 1986 and are all about LCSH on magnetic tape. Gads!

    Abstract
    Explores the question of whether academic libraries keep up with the changes in the LCSH system. Analysis of the handling of 15 subject headings in 50 academic library catalogues available via the Internet found that libraries are not consistently maintaining subject authority control, or making syndetic references and scope notes in their catalogues. Discusses the results from the perspective of the libraries' performance, performance on the headings overall, performance on references, performance on the type of change made to the headings,a nd performance within 3 widely used onlien catalogue systems (DRA, INNOPAC and NOTIS). Discusses the implications of the findings in relationship to expressions of dissatisfaction with the effectiveness of subject cataloguing expressed by discussion groups on the Internet

    Abstract
    Discusses the problems in establishing commonly accepted principles for subject retrieval between different bibliographic systems. The Working Group on Principles Underlying Subject Heading Languages was established to devise general principles for any subject retrieval system and to review existing real systems in the light of such principles and compare them in order to evaluate the extent of their coverage and their application in current practices. Provides a background and history of the Working Group. Discusses the principles underlying subject headings and their purposes and the state of the work and major findings

    Abstract
    Comments on the relative rarity of research articles on theoretical aspects of subject indexing in computerised retrieval systems and the predominance of articles on software packages and hardware. Concludes that controlled indexing still has a future but points to major differences from the past

    Abstract
    Investigates the extent to which title keywords convey subject content and compares the relative effectiveness of searching title keywords using 2 search strategies to examine whether adjacency operators in title keyword searches are effective in improving recall and precision of online searching. Title keywords from a random sample of titles in the field of economics were searched on FirstSearch, using the WorldCat database, which is equivalent in coverage to the OCLC OLUC, with and without adjacency of the keywords specified. The LCSH of the items retrieved were compared with the sample title subject headings to determine the degree of match or relevance and the values for precision and recall were calculated. Results indicated that, when keywords were discipline specific, adjacency operators improved precision with little degradation of recall. Systems that allow positional operators or rank output by proximity of terms may increase search success

    Abstract
    A movement for a subject heading code to standardize LCSH and their usage gained considerable attention in the late 1980s and early 1990s. Examines the reasons for the lack of progress in this project, which include: the lack of any plan from the LoC which could serve as a philosophical foundation for either a subject access system or the changes made to it; the belief that online catalogues make a controlled subject vocabulary obsolete; and professional ignorance, apathy, and negativism. Warns that, in an increasingly complex age, lack of standardization of any technical system or process tends to lead to the demise of that system or process

    Abstract
    Introducess a new approach to display retrieved subject headings in subject searching designed to encourage users to browse bibliographic information. Emphasizes the importance of the exact display approach by showing how many user queries could be candidates for this approach, demonstrates an implementation of the exact-display approach in an experimental online catalogue. End user experiences gives opportunities to make recommendations for enhancing the original design of the exact display approach so that future implementations of this approach in operational online catalogues are responsive to the needs of online catalogue users
