This discussion of the major issues concerning online public access library catalogs highlights types of systems, user behavior, structure of systems and user-friendly information retrieval methods (menus, fuzzy matches, prompters), and additional search strategy features (limits, browsing, truncation). Three references are listed. (EJS)

Describes a transaction log analysis of the New York Public Library research libraries' OPAC (online public access catalog). Much of the remote searching occurred when the libraries were closed and was more evenly distributed than internal searching, demonstrating that remote searching could expand access and reduce peak system loads. (Contains…

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…

Results from one of a series of cooperative projects to study public access to online catalogs are discussed. This report focuses on a survey of 1,152 users and 1,315 non-users of six computer systems at seven libraries, with library participants including (1) Claremont Colleges Library, which uses the Claremont Total Library System; (2) the…

A microcomputer and hard disk were used to set up an automated card catalog in an Edmonton (Alberta) elementary school learning resource center to determine if a computerized card catalog would help elementary students to access learning resource materials, thereby enhancing their learning. Instead of using a traditional card catalog, students…

To study the users and use of the subject searching capability offered by the new online public catalog at the New York State Library (NYSL) a study was begun before the catalog change in mid-1983 and continued for a considerable time after the change. Data were collected during three 1-week periods; one preceded the catalog change and two…

The current attitudes of users and non-users towards public online computer catalogs (OPAC's) were studied at the Library of Congress (LC) and responses were compared with those from an aggregate survey. Attitudes of both users and non-users toward the LC OPAC system were favorable. Problems experienced by patrons related to difficulty in…

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…

Designed to help institutions considering library automation, this report describes the adoption, installation, and use of the Virginia Tech Library System (VTLS) at Ohio University. The report includes information on: (1) a task force created at Ohio University in 1978 to explore an automated circulation system; (2) installation and tape loading…

Sixteen articles, books, and reports published between 1978 and 1983 and cited in "Resources in Education" and "Current Index to Journals in Education" are listed in this bibliography on online public access catalogs (OPACs). Emphasis is on the movement toward computer-based alternatives to library card catalogs and user…

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…

The Subject Access Research Project was initiated by OCLC in August 1979 to study the process of subject searching in the library catalog, with the objective of identifying features for an automated subject retrieval system which would support the present search tactics employed by library users performing manual subject searches at the library…

As part of a project which evaluated online public access catalogs (OPAC's) through analyses of library patrons' needs and perceptions, self-administered questionnaires were completed by library patrons who were OPAC users and non-users at nine academic and public libraries. Focus group interviews were conducted with OPAC users and non-users, as…

This report addresses the objectives of a national survey of users and non-users of online catalogs (OPAC's) as they apply to MELVYL and its implementation in the University of California (UC) Libraries on nine campuses. These objectives were to collect information to enable libraries to improve implementation of support services for public access…

New York University (NYU) Libraries received a 1-year grant from the Association of Research Libraries to study users' responses to its recently installed Geac online catalog, Bobcat (Bobst Library Computerized Catalog). The survey instrument, developed for Council on Library Resources (CLR)-funded national study of responses to public access…
