Presents an online search strategy to help find pairs of medical literatures that are logically related but non-interactive, meaning the two pairs have no articles in common, do not cite each other, and are not co-cited. Each stage of the search strategy is described and favorable results are discussed. (four references) (CLB)

Presents analysis of online search patterns within user searching sessions of National Library of Medicine ELHILL system and examines user search patterns on the CATLINE database. Data previously analyzed on MEDLINE database for same period is used to compare the performance parameters of different databases within the same information system.…

Relative effectiveness of indexing using full-text or less than full-text was tested using non-Boolean, chaining type of file structure and searching method. Indexing was done using titles, abstracts, full-text, references, and various combinations; Goffman's indirect method of information retrieval was used to structure and search file.…

Examines relationship between journal productivity (number of references to particular journal) and journal obsolescence (median age of references to particular journal) for database of references dealing with desalination. Citation age by Bradford zones, continuous measurement of productivity and citation age, and underlying structure of observed…

Explores response time variations in National Library of Medicine's ELHILL bibliographic search system and analyzes statistical significance of response time in terms of its variations by day of week, hour of day, particular bibliographic file being searched, command issued by user, number of users logged onto system. Ten references are cited.…

Discussion of search behavior in electronic environments focuses on the development of GRIP (Graphic Representor of Interaction Patterns), a graphing tool based on HyperCard that produces graphic representations of search patterns. Search state spaces are explained, and forms of data available from electronic searches are described. (34…

Investigation of end-user searching at National Library of Medicine reveals that volume of searching is related to convenient placement of terminal; slightly fewer than half of potential searchers search for themselves; practices of pharmacists and pathologists do not differ in important ways; end-user searchers perform simple searches. (86…

Controlled experiments conducted to compare effectiveness of enhanced experimental computer intermediary system, CONIT, with that of human expert intermediary search specialists indicate that experimental intermediary techniques are now capable of providing search assistance whose effectiveness at least approximates that of human intermediaries in…

Reviews empirical studies about how digital libraries evolve for use in scientific and technical work based on the Digital Libraries Initiative (DLI) at the University of Illinois. Discusses how users meet infrastructure and document disaggregation; describes use of the DLI testbed of full text journal articles; and explains research methodology.…
