Focuses on quantitative studies which can be made using data obtained from machine-readable catalogs and applied to actual or potential catalog use. (Author)

Study conducted at the University of Western Ontario explored whether use of keywords of an online catalog would be a satisfactory alternative to self cross referencing for locating variant subject heading forms. Random comparison of machine readable cataloging with Library of Congress authorities demonstrated the desirability of cross reference…

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…

The Institute of Library Research converted to machine-readable form over one million catalog cards representing about 750,000 Roman-language titles catalogued by the University of California (UC) libraries from 1963 to 1967. From this data base they printed the UC Union Catalog Supplement (UCUCS-1). From 1968 to 1972, an additional set of card…

This report describes efforts by three academic libraries to develop a model instructional program for online catalog users that could be adopted in other academic libraries. A key component of the research included the exploration and development of a methodology for utilizing online transaction logs to evaluate user performance. The four project…

This survey of 57 members of the Association of Research Libraries (ARL) examines technical and management issues in providing remote access to their online catalogs, as well as with instructions and services for remote users. It is noted that most ARL libraries have not yet conducted studies to project the extent of use of remote access, although…

Though recent technological developments have promised solutions to the costly problems of expanding card catalogs and changing cataloging practices, at the University of California libraries the problems have been compounded by a desire to stay compatible with the changing conventions of the Library of Congress and by an increasingly stringent…

Explains objectives of research on development of an online public access catalog using a proprietary microcomputer network being conducted by the Polytechnic of Central London; examines background of existing local area library networks, problems of network system design, and advantages of distributed processing; and summarizes research…

Reviews pilot project at the University of Southern California to convert the traditional card catalog to a COM catalog. This involved identification of essential and nonessential catalog data elements and assessment of users' reaction toward the sudden change in form and content of the catalog. (CWM)

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…

This document explores the various issues and concerns related to the development of online systems in libraries and, in particular, online catalogs. Following a preface, foreword, and introduction, chapters are devoted to each of the following topics: (l) providing for special interests including the disabled; (2) authority control; (3) subject…

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…

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…
