    Abstract
    This paper recognizes the limitations of the existing file of Library of Congress authority records for subject heading assignment and validation. It makes recommendations for a new machine-readable file of authority records for topical subdivisions and for enhancements to the existing subject authority file. The recommended changes qould enable online systems to assist in subject heading formulation and verify, with limited assistance by human intermediaries, the individual components of subdivided headings. A study of subdivided subject headings in a large bibliographic database forms the basis of the recommendations

    Abstract
    Subject queries were extracted from 3 universities' online catalogues and analysed to determine the extend to which they matched subject headings in the LCSH. Computer analyses show that nearly 25% of the subject queries entered by online catalogue users are exact matches of LCSH. Yet, manual analyses show that, even though a user matches or closely matches LCSH-mr, the citations retrieved by this vocabulary are not necessarily satisfactory. Sometimes the closest LCSH-mr is not at all pertinent to a user's topic of interest. This study presents reasons why close matches of LCSH-mr are not always satisfactory and suggests approaches to finding the best matches of the catalogue's controlled vocabulary

    Abstract
    Describes the comparative approach to system evaluation used in this research project which delegated the administartion of an online retrieval test to an experimental online catalogue to produce data for evaluating the effectiveness of a new subject access design. Describes the methods enlisted to sort out problem test administration, e.g. to identify out-of-scope queries, incomplete system administration, and suspect post-search questionnaire responses. Covers how w the researchers handled problem search administrations and what actions they would use to reduce or eliminate the occurrence of such administrations in future online retrieval tests that delegate control of retrieval tests to online systems

    Abstract
    This article describes the findings of a research project that tested a new subject-access design in an experimental online catalog that had a wide range of subject-searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Library users at 2 academic libraries searched this experimental catalog for topics of their own choosing, judges the usefulness of retrieved titles, and answered post-search questions about their searching experiences. Mixed results from a quantitative analysis (i.e., precision scores) were supplemented with the more conclusive results from a qualitative analysis (i.e., failure analysis). Overall, analyses demonstrated that the new subject-access design that featured search trees was more effective in selecting a subject-searching approach that would prooduce useful information for the subjects users seek than users would select on their own. The qualitative analysis was especially helpful in providing recommendations for improving specific subject-searching approaches to increase their effenciency, increase user perseverance, and encourage browsing. It also suggested enhancements to the new subject-searching design to enable systems to respond to the wide variety of user queries for subjects

    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

    Abstract
    Reports results of a study to examine the performance of online catalogue searches involving personal names and to recommend improvements to the basic system approach to soliciting user queries and searching for them. The research questions addressed in the study wre: how online systems can chose searching approaches on their own that are likely to produce useful retrieval; how online systems solicit queries from users; and how users respond to an experimental online catalogue that prompts them for the different elements of their personal name queries. Improvements include: the implementation of a new design for online catalogue searching that features search trees; new methods for soliciting user queries bearing personal names; and enlisting the participation of online catalogue users in the evaluation of system prompts, instructions, and messages that request input from them

    Abstract
    Library users continue to experience difficulty in using the online catalog, particularly in the area of subject access. This project describes a test of a new design for subject access to online catalogs. The new design requires a wide range of subject searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Is the performance of search trees superior to subject searching approaches chosen at random? This project is geared to make that determination

    Abstract
    Recognises the limitations of the existing files of Library of Congress name and subject authority records for indirect geographic subdivision. Makes recommendations for enhancements to existing authority records, which would enable online systems to assist in subject heading formulation and verify, with limited assistance by human intermediaries, whether geographic subdivision is authorized for use with a particular main heading and whether the correct form of indirect geographic subdivision is authorized for use with a particular main heading and whether the correct form of indirect geographic subdivision is given. A study of subdivided subject headings in a large bibliographic data base forms the basis of the recommendations

    Abstract
    The impetus for a large-scale study on subject heading understanding was a recommendation of the Library of Congress (LC) Subject Subdivisions Conference that suggested standardizing the order of subject subdivisions for the purpose of simplifying subject cataloging. This paper focuses on unexpected large-scale study findings about multiple meanings for subdivided subject headings and the effects that changes of meaning for different orders of subdivisions had on the meanings that end users and librarians provided to subdivided subject headings. Findings about changes of meaning in subdivided subject headings did not dissuade the authors regarding their recommendation that the library community adopt a standard order of subdivisions. The authors also give suggestions for additional studies of subject heading understanding that build on this one.

    Abstract
    This paper recognizes the limitations of the existing file of Library of Congress (LC) subject authority records for subject heading assignment and validation. it makes recommendations for a new file of machine readable authority records for period subdivisions and for enhancements to the existings file of subject authority records. Recommended changes would enable online systems to assist in subject heading formulations and verify, with limited assistance by human intermediaries, the individual components of subdivided headings. The recommendations are timely in view of changes to the forms of period subdivisions that the Library of Congress is studying to facilitate the display of period subdivisions in chronological order. The availability of machine-readable authority records for most period subdivisions would enable online systems to automatically make changes to the forms of period subdivisions in bibliographic records using cross references for previously-used forms in the autority records for the new forms. The paper also discusses issues arising from an enhancement of the existing controlled system of period subdivision. A study of subdivided subject headings in a large bibliographic database forms the basis of the recommendations
