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

Abstract: In an interview with Robert P. Holley, Karen M. Drabenstott provides a history of a professional career that has focused on subject access to information. Since her early work with Pauline Cochrane, she has strongly supported enhanced bibliographic records as a way to improve user access in the online catalog. Her Dewey Decimal Classification Online project showed that the classification offers increased subject retrieval. Her current projects include improved strategies for Web searching and multimedia literacy including subject access.

Abstract: Reports an empirical study of online catalogues accessible over the Internet and discusses the problems revealed in subject searching them. Suggests 4 tools to improve subject searching: search trees, an online directory of collections strengths of Internet accessible library collections, aids to find this record or simular records, and common command language for every Internet accessible library catalogue or bibliographic database

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

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
