As a continuation of research into online public access catalog systems (OPAC's), this study focused on the actual use of OPAC's and on refinement of the methodologies used in carrying out transaction analysis studies. Current patron use patterns were obtained via machine-readable catalogs from four online public catalog systems: The Library of…

Retrievability of titles of 152 periodicals were compared in a fixed-length algorithmic search (Library Computer System) and a keyword search (Washington Library Network) to determine which type of search algorithm is more successful with titles of varying lengths. Three references and a list of English language stopwords are appended. (EJS)

This report focuses on a discussion of findings from analyses of computer transaction logs contributed by four of the online catalog systems used in the Public Access Project. It supplements the analyses of User and Non-User Questionnaires by providing analyses of data from the systems themselves. The four systems contributing data to this…

This survey assessing use of online databases in marine science libraries indicates that, despite generally small staff and collection size, there is considerable involvement in OCLC and computerized reference service and active planning for public catalogs, serials automation, and integrated database management systems. Eleven references and…

Designed for use by study coordinators, library supervisors, and data collectors, this manual is the basic reference and training document from the 1982 field survey of public online catalog users and nonusers in 31 U.S. research, academic, community college, public, and governmental libraries. The field survey was coordinated by the Research…

From the library's viewpoint, collection growth and the need to frequently update index terms make automation almost inevitable. But this triumph of technology over print is hard on scholars, who find microforms and printouts difficult to read and who cannot browse a database like a shelf or card catalog. (SJL)

This review of the transition from library card catalogs to online public access catalogs (OPAC) (1981-1982) discusses methods employed by online catalog use studies (self-administered questionnaires, OPAC transaction logs, focused-group interviews, feature analysis, online search and retrieval experiments) and new directions for OPAC research…

Suggesting that the library catalog of the future should be an analytic catalog, this article reports that sample of books in a community college library showed that approximately 20% were collections or anthologies containing an average of 30 works each. Advantages and costs of analytical catalogs are considered. (6 references) (EJS)
