Explains seven types of subject descriptions commonly used in databases--hierarchical classification, category codes, subject headings, descriptors, faceted classification, post-controlled vocabulary, and natural language--and describes specific search techniques for taking advantage of the strengths of particular types of vocabularies. An overall…

Argues that online search capabilities are a form of indexing and that access is determined by the total mix of preexisting and added "search capability" indexing. The design of a "superthesaurus," geared to the needs of users and to online rather than manual searching, is proposed as part of a user friendly interface. (19…

Discusses indexing and access to digital resources, especially on the Internet. Topics include subject searching versus indexing; multiple terms of access; folk classification; basic level terms; folk access; Bradford's Law; Zipfian distributions; vocabulary scalability; the Resnikoff-Dolby 30:1 Rule; domain-specific indexing; and implications for…

Based on the results of a two-year study conducted by the Getty Art History Information Program of online searching by humanities scholars, implications are drawn for the design of information products. Topics include characteristics of humanities scholars; design and content of databases; indexing vocabulary; and interfaces and command languages.…

Discussion of the information needs and information-seeking behavior of interdisciplinary scholars and students focuses on kinds of research needed at both basic and applied levels. Topics include prior research; the organization, description, and indexing of information in libraries for successful information retrieval; and research techniques in…

Presents a model for the design of online catalog subject access based on three principles: the uncertainty of subject indexing, the need for greater variety in searcher's queries, and the complexity of the search process. The proposed system is based on existing Library of Congress subject cataloging. (EM)

Reports a study that analyzed natural language search statements constructed by 22 Getty Visiting Scholars as they researched humanities topics on DIALOG. Results show a greater use of names, geographical areas, chronological periods, and discipline terms than scientists use, with implications for the design of humanities online systems and…
