Discusses characteristics of typical online public access catalogs (OPACs) and examines patron use via printouts of transaction logs for three separate systems. Desirable features of OPACs (mnemonic search commands, boolean operators, forgiveness or automatic truncation, browsing a subject heading index, suggestive prompts) and need for…

Results of field study measuring end-user perceptions of sources of information (computer-based, libraries, individuals) suggest that accessibility is multidimensional concept encompassing physical access to source, interface with source, ability to physically retrieve potentially relevant information; and perceptions of accessibility are…

Library use and user studies (1973-1981) indexed in ERIC database were analyzed to ascertain areas in need of research as characterized by Tobin. Since 1972, most research conducted has been in large-scale studies and use of nonprint materials; use of government documents and library staff needs remain unresearched areas.

This report describes a computer-monitoring study of users of the Ohio State University Libraries' online catalog, an established and heavily used information retrieval system. Designed for end users, online library catalogs require little or no formal training, and often replace an existing manual system. Data were gathered unobtrusively by…

Findings of study of online searchers' self-supported behaviors and attitudes indicate that: there are wide individual differences among online searchers in attitudes and behaviors; searchers from academic institutions differ from counterparts in other library settings; experience appears to be positively related to flexible, trial-and-error…

A multifaceted card catalog use study was conducted at University of Illinois Music Library to determine hourly rate of use at sound recording and book/music catalogs; time spent at catalogs; who uses catalogs and why; difficulties users encounter; success rate of users' searches; recommendations for designing online catalog. (16 references)…

Findings from national survey describing sources that were used to obtain information about mental health topics by individuals in various settings demonstrates: importance of person-to-person communication; differences in sources used and value placed on sources; information-seeking episodes generally involve using multiple sources to obtain…

A survey of 430 users of online catalog at Ohio State University Libraries found that most users are undergraduate students (68 percent) and that majority (95 percent) choose online catalog as first source of information. Fewer performed known-item searches and success rates were generally higher than reported in earlier studies. (8 references)…

This pilot study on the subject access problems of patrons of small to medium size libraries was designed to measure the extent to which users' vocabularies matched the search vocabulary of bibliographic records in the card catalog, and to enhance subject access by develooping a microcomputer system which integrated Library of Congress Subject…

Presents results of study evaluating reactions of 20 university students and faculty to first-time online database searching on the Bibliographic Retrieval Service's menu-driven BRS/After Dark. Background information on participants, search analysis and problems, end user education needs, and the role of the intermediary are discussed. Four…

The situational and personal factors affecting the usage of a computer based information service by health care professionals are described. Of 166 health care professionals who were identified as potential users of MEDLINE at the University of Connecticut, 126 carried out one or more online searches. Pre-use and post-use questionnaires were…

Reports on the Online Catalog Public Access Project, a survey of users and nonusers in 31 U.S. libraries conducted for the Council on Library Resources. Characteristics of users, tasks, library setting, and system interface that affect user satisfaction are identified. A 25-item bibliography and user questionnaire are appended. (7 references) (EJS)

Designed to evaluate the usefulness of the BIOSIS PREVIEWS database when searching the psychiatric literature, this study compared the effectiveness of this online database with the effectiveness of two other computerized databases, MEDLINE and PsycINFO (Psychological Abstracts), which psychiatric researchers and clinicians usually rely on when…

Describes a study of library users' search strategies which focused on the extent of subject searching activity when using bibliographic tools and shelf browsing. The use of the results to evaluate the impact of a future online catalog on search behaviors is discussed. (23 references) (CLB)

Reviews the literature on user studies in both online catalogs and bibliographic retrieval systems. User problems with both mechanical and conceptual aspects are reviewed and potential sources of problems due either to individual characteristics or system variables are discussed. Possible solutions and areas that need further research are noted.…
