The prototype AID system for search strategy formulation currently operational on TOXLINE is described. Utilizing a compressed in-core hash table, it relies on statistical frequency distribution information about term occurrence in a set of document texts retrieved in response to a Boolean search query, and the occurrence frequencies of the same…

Discusses and differentiates between four commercially available versions of the online source of chemistry information, "Chemical Abstracts": Lockheed, SDC, BRS, and NLM. Disadvantages/advantages of the vendors are considered, and tables are used to show the different print formats and data elements of each version. (JD)

Describes for researchers in language, literature, and folklore the MLA (Modern Language Association) International Bibliography, which is available for searching online: history, scope, compilation and sources, languages, print v online access, searchable fields, and future plans. (JD)

Examines the relative benefits and searching philosophies of five major search systems (DIALOG, ORBIT, BRS, NLM, and DOE/RECON) as a selection aid. Differences in command language, full text searching capability, use and expression of Boolean operators, and searching mechanisms are discussed, and comparison charts and system/database comparisons…

Describes a study that used qualitative and quantitative methodologies to analyze differences between Finnish and American Web searchers in their choice of initial search strategies (direct address, subject directory, and search engines) and their reasoning underlying their choices.

Discussion of retrieval overlap and relevant overlap focuses on an analysis of data from an earlier study on overlap among document representations. This new analysis investigated the odds that an item was judged relevant when it was retrieved by two search fields as opposed to being retrieved by only one field. (Contains 17 references.) (LRW)
