Researchers studying subject searching distributed an online questionnaire to users who access the University of California's online public access catalog, MELVYL, from public access terminals in the libraries of the University of California at Santa Cruz. This article discusses the results of transaction log analysis, comparison of in-library and…

Describes a study that examined the search behavior of remote users of the University of California MELVYL online public access catalog by analyzing the transaction logs. Highlights include the number of searches, databases searched, number of retrievals, constructing search commands, problems with search terms, and effectiveness of searches.…

Describes a user study by library students to assess user attitudes toward the format and information contained in a microfiche catalog. While indicating general user approval, the survey did not discriminate between views of the catalog as a basic finding tool and as a continuation of traditional card catalog information content. (RAA)

Presents a model that calculates the conditions under which a library may adopt a highly service-oriented online catalog access policy at minimum additional cost. The use of arrival rates, service rates, and queueing calculations to arrive at a cost-effective policy is explained. (Author/CLB)

Explores issues surrounding efforts to introduce online catalogs to users and presents relevant research results from Northwestern University's "Educating the Online Catalog User" project. Highlights include attitudes and preconceptions about online catalogs and instruction, research on online catalog use, suggestions for online catalog teaching,…

Findings of focused-group interviews conducted for OCLC study of library users and online public access catalogs (OPACs) indicate users like OPACs, have problems finding right subject heading, envision features to improve subject access, want access to more than books, and want OPACs to provide new services. Eight references are listed. (EJS)

Discusses a study conducted at Ohio State University Libraries to develop and test a model that accurately estimates number of terminals required in an online public access catalog system. Data collection, research methodology, standard statistical distributions, and queuing models are noted. Four references are cited. (EJS)

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 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)

Describes research strategy and methods of comparative evaluation conducted by the National Library of Medicine to assess user acceptance and technical performance of two prototype patron accessible online catalog systems within same operational environment. User acceptance studies included sample search experiment, comparison search experiment,…

A survey at the University of Houston examined factors related to subject searching success in online catalogs, including: extent of subject searching; response to unsuccessful searches; reasons subject search is not used; users' awareness of sources of subject terms; and suggestions from users for improving subject searching capabilities. (CLB)

Describes an analysis of transaction logs of the online catalog at the University of Missouri-Kansas City that examined patron use of both controlled and uncontrolled vocabulary subject access during the same search session. Hypotheses tested are discussed, and recommendations are made for library instruction and online catalog design. (six…

This review of the overall findings of the "Educating the Online Catalog User" project at Northwestern University Library focuses on methods of data collection used in evaluating online catalog performance and user performance. The rationale and methodology of transaction log monitoring and new directions for technical development are…

Describes an evaluation of variability in the percentage of subject searching in an online catalog among branch libraries of one university. The results reported include variability by time of day, day of week, and week of semester. The value of this type of information for library administration is discussed. (CLB)

Offers a model for choosing among CD-ROM, end user access, mediated online searching, or locally mounted files as alternatives for extending online catalogs and replacing printed indexes. Estimates of demand and comparisons of costs made at Trinity and Clemson Universities provide a quantitative framework for selection. (Contains four references.)…
