Reports results of an electronic survey of users of CD-ROM databases at a university library. Data are presented on experience level, database selection, how users learned of the service, use of multiple databases, favorite features, user satisfaction, preferred source of help, research strategies, and use of printed versions. A copy of the…

Fourteen undergraduate students who had successfully completed research projects were surveyed on their research processes, including focusing their topic, finding and using evidence, and writing. Their responses revealed significant differences between the way they actually do research and standard search strategies, and the implications of these…

This overview of the research process for the novice information retrieval (IR) researcher provides guidance on selecting a research question, choosing the type of test, defining variables, developing or using databases, finding and processing queries, assigning treatments to experimental units, collecting and analyzing the data, and presenting…

Discussion of search strategy formulation focuses on a study at the University of North Carolina at Chapel Hill that analyzed how medical students developed and revised search strategies for microbiology database searches. Implications for future research on search behavior, for system interface design, and for end user training are suggested. (16…

Issues addressed include subject cataloging, including Library of Congress Subject Headings (LCSH); classification, including Dewey Decimal Classification (DDC), Library of Congress Classification, and classification in online systems; subject access, including the online use of…

Describes use studies of CD-ROM products in American and western European academic, public, and special libraries. Comparative results of the surveys are reported, including effect of CD-ROMs on library use of online databases, difficulties with different vendors' search techniques, and desired subjects of optical products. (10 references) (LRW)

Discussion of bibliographic instruction for users of CD-ROM products highlights computer-based tutorials (CBT) that were developed at the School of Library and Information Science at the University of Western Ontario. Structured searching is described, and problems created by the lack of commercial CD-ROM tutorials and adequate training videos are…

Suggests ways that the school library media specialist can help students become more successful as users of online information. Four types of barriers to becoming informed are described: (1) indicative access barriers (indexing systems and relevance); (2) physical access to documents identified in a search; (3) linguistic barriers; and (4)…

This study of an online search strategy based on word frequency found that it provided 98% sensitivity in retrieving systematic reviews of health-care interventions in MEDLINE, while retaining a low (20%) but acceptable precision. Presents other strategies with other levels of sensitivity and precision and discusses factors that may affect the…
