Data collected from analysis of the University of South Dakota's uninhibited database selection and use policy are evaluated as an aid in developing a cost-efficient database searching strategy. Statistics are presented which clarify the effectiveness of single and multiple database use. (SW)

Reports on a study that investigated the effects of subject knowledge and search experience on tactics used by novices and experienced searchers in online searches. Results of an experiment conducted with 32 undergraduate students and 32 professional searchers, and implications of the findings for system design are discussed. (52 references) (KRN)

To assist librarians to better understand the information needs of industrial vs academic patrons, this study considers the purpose of searches, the sources checked prior to requesting searches, search characteristics, users' opinion of search results, and typical search profiles of the two groups.

Reports on a study of keyword and Boolean searching by users of an online public access catalog (OPAC) at the University of Oklahoma. Results of survey questionnaires and transaction log analysis indicate users search more often by keyword, even though the search usually fails and they don't understand it. (15 tables) (Author/LRW)

Describes a study conducted at Baruch College of the City University of New York that assessed the search techniques of trained endusers and determined whether or not they were searching the full-text system effectively. Correlations between native language and searching results and satisfaction are shown, and implications for training are…

Describes results of a study of transaction logs from three university libraries' online catalogs that analyzed subject queries to determine the extent to which they matched subject headings in the Library of Congress Subject Headings (LCSH). Computer and manual analyses are described, and user satisfaction with LCSH matches is considered. (14…

College students were trained to do online searching in a mandatory research paper course. Bibliographies from student papers, search transcripts, questionnaires administered to students, the library's serials holdings, and interviews with instructors and librarians provided data for analyses of students' database and library searches and the…

An analysis of 100 online public access catalog (OPAC) search sessions explored the effectiveness of converting unsuccessful subject searches to keyword searches. It is suggested that either a system generated message to the user to try a keyword search, or an automatic conversion of zero-hit searches might be effective in improving search…

Describes a longitudinal study of four sets of OPAC (online public access catalog) transaction logs that examined the effects of screen changes in helping searchers improve their search behavior. Results show that while screen changes initially had a positive impact on search behavior, they were not always sustained over time. (Author/LRW)

Describes a study that used the shelf availability research methodology to identify and quantify the causes of users' failures to identify and locate library materials. The factors resulting in unsuccessful searches are discussed, and recommendations for reducing these factors are made. (26 references) (CLB)

With grants from the Council on Library Resources (CLR) and the Association of Research Libraries (ARL), New York University (NYU) Libraries conducted a study to assess user reactions to their online catalog, Bobcat (Bobst Library Computerized Catalog). In order to evaluate the effectiveness of NYU's catalog, to describe users' attitudes toward…

Presents preliminary data that characterizes the relationship between what users say they are trying to accomplish when using an online public access catalog (OPAC) and their perceptions of what input to give the system. Human-machine interaction is discussed, and appropriate methods for evaluating information retrieval systems are considered. (18…

Describes a study conducted at the Hebrew University of Jerusalem to determine whether users doing bibliographic searches in ALEPH (Automated Library Expandable Program Hebrew University), a bibliographic utility with a decentralized database, searched the online catalog of the library where they were working or whether they accessed other…

Reports results of a survey of online catalog users in an academic library in Saudi Arabia that examined search patterns, levels of satisfaction, and user attitudes toward the online catalog. The special problems encountered when searching in a foreign language are discussed, and systems improvements are suggested. (CLB)

Analyses of the success-failure rates and user reactions using four public access online systems indicate that users overwhelmingly preferred the online to manual systems. Improved subject access emerged as the salient feature requiring improvement. Seven references are included. (Author/RAA)
