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…

Review of research on online public access catalogs sponsored by Council on Library Resources notes the scope and method (questionnaires administered to catalog users and nonusers in 29 participating institutions) and findings and applications (including organizational setting and computer system, catalog use and satisfaction, and implications).…

Findings of study of user perceptions of online public access catalog in an academic library system indicate that: most patrons learned to use system from printed instructions; next most frequent sources of information were library staff and help feature; most patrons were extremely satisfied with system. Six references are cited. (EJS)

A survey of 430 users of online catalog at Ohio State University Libraries found that most users are undergraduate students (68 percent) and that majority (95 percent) choose online catalog as first source of information. Fewer performed known-item searches and success rates were generally higher than reported in earlier studies. (8 references)…

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)

Suggests improvement to online catalogs based on a 2 1/2 year study of patron search patterns. Preliminary findings indicate significant differences in search strategies and suggest that these strategies and the reasons patrons choose them should be important factors in the design of future online catalogs. Fourteen references are included.…

Discussion of the influence of library catalog use studies on cataloging codes and practices focuses on a study of reference staff members at three Association of Research Libraries academic libraries that was conducted to determine their use of bibliographic record elements. Records in online catalogs and bibliographic utilities are examined, and…

Describes results of a survey conducted at Indiana State University libraries that studied patron perceptions and demographics related to keyword searching on LUIS, the online public access catalog (OPAC) available through NOTIS (Northwestern Online Total Integrated System.) Demographics studied include age, status, frequency of LUIS use, and…

Analyzes queueing statistics to determine their utility in predicting catalog usage and the relationships between card and serials catalogs and to pinpoint peak catalog usage. This measurement should provide one factor in a simulation model to accurately predict the number of catalog devices needed for alternative catalog formats. Eight references…

Presents a methodology for describing, analyzing, and evaluating the public service functions of serial file systems, and describes a user study conducted in a university departmental library to determine the efficiency and effectiveness of its system in enabling students new to the library to locate known-items in the serials collection.

Results of study on patron information retrieval success and patron use patterns at Ohio State University show that 90 percent of online users preferred online to card catalog; 64 percent of those who tried online catalog switched to it; and patrons used the online more than the card catalog.
