Review of research methodologies used in studies of online public access catalog (OPAC) users finds that a variety of research methodologies--e.g., surveys, transaction log analysis, interviews--have been used with varying degrees of expertise. It is concluded that poor research methodology resulting from limited training and resources limits the…

Reviews research on impact assessment of libraries and considers potentially useful methodologies for measuring the impact of university libraries, i.e., how library use affects students' academic performance. Topics discussed include categories of library use, purposes of library use, and indicators of library impact. The user panel methodology…

Develops a conceptual model which places public library use in the context of a series of interrelated decisions made by consumer about allocating time to various activities based on relative costs and benefits, and tests the model against available data on the characteristics of public library users. Seventeen references are included. (EJS)

Discusses the accuracy of reference service in libraries as measured by evaluating answers that reference librarians give to factual questions. More than 30 reference accuracy studies are analyzed, variables explored in each study are examined, further research needs are described, and suggestions for improving service quality for reference…

Public library effectiveness efforts are placed within the context of theoretical and empirical research on organizational effectiveness. The construct, measures, and determinants of public library effectiveness are investigated, and a possible model of the determinants of public library output measures is presented. (Author/EM)

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…

Describes analyses of 3 searches conducted in an academic library by 11 novice users of full-text databases. The study examined affective search behavior, search strategies, and searcher assessments of retrieved material. Results of interviews, transaction log analysis, and audiotape recordings of search sessions are discussed, and further…

Describes a study of the Tel Aviv library system that examined the factors influencing the service range distances of branch libraries and the differences among them in amount of library use. The literature of spatial aspects of public services is reviewed, the geostatistical methodology is explained, and socioeconomic factors are discussed. (19…

Describes a study which was conducted to test the ability of four motivators to explain adult use of the public library: (1) home and family life; (2) vocational growth; (3) religion; and (4) politics. Other general user characteristics were examined as supplements to the four motivators in predicting library use. (16 references) (LRW)

Presents longitudinal case studies of four students in high school and after completion of college to compare their perceptions of the information search process in libraries. Library user studies are discussed, a model of the search process is described, and implications for the design of information systems are suggested. (36 references) (LRW)

Discusses issues relating to the reliability, validity, utility, and information value of unobtrusive testing of library reference services; provides suggestions for practical applications of these criteria; applies study findings to library decision making and planning; and identifies topics for further methodological refinement. (Author/CLB)

Discussion of the gender gap in computer-related activities focuses on a study of high school seniors that examined sex differences in library anxiety, computer anxiety, and anxiety in using computers for library research.
