Discusses recent changes in the Library of Congress Subject Headings (LCSH), arguing that the adoption of the well-recognized codes for thesauri has created confusion because the LCSH is not a true thesaurus. The distinction between subject headings and terms are clarified and a possible solution to the problems with the LCSH is suggested. (5…

Analyzes four descriptive cataloging orthodoxies of the past (corporate authorship, uniform personal headings, the main entry, and the dominance of the card catalog) and contends that each has been overthrown. The influence of the MARC format on descriptive cataloging is examined and the need for the application of utilitarian principles is…

Review of the 1987 subject access literature covers: (1) general works; (2) organization, history, theory, and method of classification; (3) classification systems; (4) subject headings and the Library of Congress; (5) subject authority control through the Library of Congress Subject Headings; (6) subject searching in online catalogs; and (7)…

This review of the 1986 literature on subject access covers: (1) general works; (2) organization and history; (3) classification systems; (4) classification theory and method; (5) Library of Congress Subject Headings (LCSH); (6) authority control through LCSH; (7) subject searching through LC-based, assigned subject headings; and (8) other subject…

Investigates methods of compressing headings identified by MARC subfield codes to reduce the size of browsable displays. An argument is made for sorting subdivisions by a conceptual, rather than an alphabetical, approach to present efficient browsable displays and relieve the user of the burden of data organization.

Describes the development and implementation of software that provides a global change capability by allowing correction of a single heading in a large file of bibliographic records through programatic identification and replacement. Specific change processes are described, including name headings, geographic headings, and topical subject…

Traces the development of online public access catalogs (OPACs) and compares what has occurred with a 1964 article that outlined recommendations for a future card catalog. Subject access is emphasized, including Library of Congress Subject Headings, expansion of OPACs, user-friendly interfaces, new technologies, and current visions of the future…

Describes a study that collected statistics on the occurrence of terms used in searching an online catalog and investigated the correlation of the selection of terms with their occurrence in indexing. The discussion of the results includes implications for indexing theories. (19 references) (CLB)

Discusses the graphical user interface (GUI) online public access catalog (OPAC), a user interface that uses images to represent options. Topics include user interface design for information retrieval; designing effective bibliographic displays, including subject headings; two design principles; and what GUIs can bring to OPACs. (LRW)

Discusses problems with subject searches in online library catalogs and examines theoretical principles for the design of effective information retrieval systems. Probabilistic ranking methods are discussed, and an experimental online catalog called CHESHIRE is described. It is noted that CHESHIRE uses classification clustering, provides natural…

Describes a survey that examined ways in which users interacted with the authority control of online catalogs developed commercially and locally. The two types of system are compared in terms of displayed messages related to authority control and system capabilities to aid users in understanding the relationships between headings. (CLB)

Presents the evolution of subject access to works about individual corporate bodies in Anglo-American subject cataloging practice. Comparison is made to works of individual biography, the lack of comparable subject access is explored, and recommendations are made to restore parity by using syndetic reference structure through automated maintenance…

Discusses the need for a subject cataloging code in order to evaluate subject catalog effectiveness, take advantage of online technologies, and keep the subject headings list current. Impediments to a code, both practical and philosophical, are identified. Practical suggestions for improving subject cataloging without a theoretical code are…

Discusses the problems involved in assigning descriptors to works of art for online museum catalogs. The topics covered include the subjectivity of the analysis of art, factors that affect the cataloging of museum collections, and the online systems developed by various museums.

Investigation of retrieval performance of controlled vocabulary derived from natural language terms in tables of contents and book indexes assumed that controlled vocabulary representative of users' queries should adequately represent documents' contents. Queries were indexed using Library of Congress Subject Headings (LSCH), Dewey Decimal…
