Reports on microcatalog use studies conducted at the University of Oregon which demonstrated that users encounter difficulties with multiple-file microfiche catalogs. Retrospective conversion strategies and the costs of converting records into machine-readable form are considered. Thirty-five references are listed. (FM)

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…

Microcatalog use studies at the University of Oregon have demonstrated that users encounter access difficulties when confronted with a multiple file microfiche catalog. This research verifies theories by Mooers, Zipf, and others that the public minimizes search efforts and implies that closed catalogs with supplements such as add-on catalogs will…

Describes methods used at the University of Akron (Ohio) library to increase the usage of government publications, including cataloging that appears in the online catalog, integrating them into bibliographic instruction, listing in pathfinders, and presenting workshops. Examples are appended. (LRW)

Uses continuous-time stochastic models, mainly based on semi-Markov chains, to derive user state transition patterns, both in rates and in probabilities, in a Web-based information system. Describes search sessions from transaction logs of the University of California's MELVYL library catalog system and discusses sequential dependency. (Author/LRW)

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…

Describes a study that compared figures derived from a questionnaire-based, book availability survey and from computer records of the use of the library's catalog. Although differences emerged, it was concluded that the computer monitoring technique could act as a surrogate for availability surveys. (AEF)

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…

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…

Discussion of user persistence in displaying postings from an online catalog focuses on a study at the University of Illinois at Chicago that compared results of an earlier study of user persistence with a recent study of users and their online catalog, LUIS. Results of questionnaires and transaction log analysis are reported. (LRW)

The purpose of this research project was to develop techniques for analyzing user searches of the Syracuse University Libraries Information Retrieval Systems (SULIRS) to enable library staff to identify and test potentially high payoff modifications to the system and/or to user documentation. The first task was an exploratory analysis of recorded…

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)

This study examined the effect of the availability of an academic online catalog on the use of academic libraries by college-bound high school seniors to determine: (1) degree of academic library use in connection with research projects; (2) use of the catalog to search for library materials; and (3) the nature of library materials used. (12…
