This study compared Social Work Abstracts and Social Services Abstracts databases in terms of indexing, journal coverage, and searches. The authors interviewed editors, analyzed journal coverage, and compared searches. It was determined that the databases complement one another more than compete. The authors conclude with some considerations.

Compares two information retrieval systems, CLARIT and TOPIC, in terms of assigned versus derived and precoordinate versus postcoordinate indexing. Models of information retrieval systems are discussed, and a test of the systems using a demonstration database of full-text articles from the "Wall Street Journal" is described. (Contains 21…

A comparison of ERIC and LISA (Library and Information Science Abstracts) indexing of the three journals--Online, Online Review, and Database--revealed some differences but more similarities in number of terms per article and concepts per article. A vocabulary which distinguished the field of online searching did emerge. (Author/EM)

This paper compares the subject indexing on articles pertaining to Immanuel Kant, agriculture, and aging that are found simultaneously in Humanities Index, Academic Search Elite (EBSCO) and Periodicals Research II (Micromedia ProQuest), in order to show that there are substantial variations in the depth and quality of indexing in these databases.…

Describes a study evaluating the effectiveness of the Information Retrieval, Ltd. (IRL) Life Sciences Collection database in a field where BioSciences Information Service (BIOSIS) claims to offer comprehensive coverage of the international literature. The two databases are described, and the depth of controlled indexing is compared for the two

A comparison of the Magazine Index (MI) and the New York Times Information Bank (IB) showed the two data bases have little in common, mainly due to differences in focus, indexing, vocabulary, use online, and output. For business and government users, IB is the best choice; for more general and academic purposes, MI provides access to more…

Discusses strengths of abstracting and indexing services (subject coverage, resolution of language problems, systematic indexing) and summarizes sources, countries of origin, languages, total coverage, and indexing of four scientific and technical services--Biosis, Engineering Information, Inspec, Chemical Abstracts Service. Characteristics of…

Provides an overview of robots that retrieve World Wide Web documents and index data and then store it in a database. Nine robot-generated databases are described, including record content, services, search features, and sample search results; and sidebars discuss the controversy about Web robots and other resource discovery tools. (LRW)

This comparison of bibliographies/online databases regarding their classification schemes, periodicals list, coverage of articles, indexing, and overlap reveals that only five bibliographies cover whole of subject area, and differences exist between number of periodicals scanned (73 to 2,771) and percentage of articles included from six…

Presents an improved inverted region quadtree variation called Dynamic Inverted Quadtree that is able to support and index a pictorial database. Pattern-searching algorithms are described, and the space needs of Fully Inverted and Dynamic Inverted Quadtrees are analytically compared based on a model of image randomness expressed as a branching…

In order to compare effects of input processing on information retrieval in three databases, 25 articles from a specific journal were examined. Tables and Venn diagrams show retrieval results from different manual and computer searches. The relation between document surrogates and subject matter of the documents is discussed. (SW)

Discussion of Web databases, or search engines for the Internet, presents a series of questions that can be used to analyze these tools based on library literature. Six search engines are analyzed; collection methods, indexing, and abstracting are compared; and a proposal for a future ideal Web database is included. (Author/LRW)

Discusses the cost of constructing a hypertext database and suggests cost forecasting approaches that can be used to determine whether organizations can internally fund a hypertext database, or whether producers can afford to market hypertext databases. Production costs in differing hypertext strategies are also compared. (27 references) (LRW)

References indexed for Australian Education Index (AEI) were sampled and compared where possible with same references indexed for ERIC and Australian Public Affairs Information Service (APAIS) databases. An analysis of coverage of Australian references reveals indexing consistency figures of 22 percent for ERIC/AEI and 18 percent for AEI/APAIS.…

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)…
