Reports on a study that examined scope notes added to subject headings in the Library and Information Science Abstracts (LISA) Online User Manual. Types of messages conveyed by scope notes and word patterns within the notes are identified, and comparisons between the 1982 and 1987 editions of the manual are made. (16 references) (MES)

This report describes recent efforts to modify, test, and evaluate an experimental online database consisting of 15 vendor-supplied, controlled subject vocabularies or thesauri. The experimental database, called the Vocabulary Switching System (VSS), is designed to enhance search strategies and ultimately retrieval performance for users of online…

Examines the differences between terms used in four major computerized information retrieval systems in education--British National Bibliography (PRECIS); ERIC; European Documentation and Information System for Education (EUDISED); and the International Bureau of Education (IBE) thesaurus. The possibility of standardizing terminology across all…

Considers the quality of bibliographic control achieved by the three online databases offering significant coverage of the literature of librarianship: ERIC, LISA, and Library Literature. Focusing on coverage and indexing, the study compares online search results with the tables of contents of 67 journals and reports the results. (27 references)…

Describes and compares the nine online databases that index the Washington Post. Points of comparison include materials that are excluded from the database, citations to excluded materials, citation formats, search vocabularies and strategies, full-text searching, cross-file searching, and search costs.

Describes a study that compared the coverage of the nursing profession, subject heading specificity, and ease of retrieval of the MEDLINE and Nursing & Allied Health (CINAHL) online databases. The strengths and weaknesses of each database are discussed and hints for searching on both databases are provided. (four references) (CLB)

Explores the underlying concepts involved in the design of art scholarly databases and describes three systems definition projects currently in progress. The discussion covers the revisions of MARC formats and authority controls used in bibliographic information networks that might support an art scholarly database. (eight references) (CLB)

The first article describes SPORT, a database providing international coverage of athletics and physical education, and compares it to other online services in terms of coverage, thesauri, possible search strategies, and actual usage. The second article reviews available online information on sports medicine. (CLB)

Includes description of the Educational Resources Information Center (ERIC), critical examination of the ERIC Thesaurus' structure and design, and a discussion of its descriptors, scope notes, multiword terms, coverage, and linguistics. Four online searches are described and search subject treatment in three other educational thesauri are compared…

Describes a study of professional searchers that investigated their decisions about using search terms. The use of descriptors from a controlled vocabulary versus the use of textwords for free-text searching is examined, searching styles and differences in subject areas are discussed, and the quality of thesauri and indexing is considered. (six…

Discusses databases available for online searching in the humanities fields and describes searches that investigated scatter (i.e., the spread of subject terms across the databases), overlap among online files in terms of retrieved records, and the comparative effectiveness of natural language versus controlled vocabulary for information…

Analysis of current methods for achieving compatibility or convertibility between two or more indexing languages draws attention to the need for a switching language to establish equivalency between concepts, not terms. In order to examine the assumption of the conceptual equivalency of identical terms in the indexing languages of related subject…

POPLINE, a cooperatively produced bibliographic retrieval system offered through MEDLARS, is a comprehensive collection of the worldwide literature on population and family planning. A comparison of several medical and social science databases with POPLINE indicates that POPLINE offers the greatest depth and breadth of subject coverage in this…

Two subject profiles (social welfare direct practice and management) were used to search 13 social science databases in order to examine extent of online coverage of social welfare literature. Journal coverage data for 20 titles were obtained and most recent citations were retrieved to compare currency of indexing (5 references). (EJS)

Assesses the major databases for retrieval of mental health information (PSYCINFO, MEDLINE, NIMH) on the basis of journal coverage, controlled vocabulary, abstracts, and performance in actual searches.
