- Abstract
- The authors conducted a six-week queueing study of public catalogs in the Iowa State University library system. Data gathered are analyzed primarily to determine if routinely gathered library statistics can validly be used to predict catalog usage, to discover the ratio between the usage of the card catalog and the serials catalog, and to pinpoint the time of peak card catalog usage in order to measure more closely the rate of use. This measurement, then, provides one factor in a simulation model that can be constructed to predict accurately the number of devices needed for an alternative catalog format

- Abstract
- A controlled set of searches have been conducted by a group of searchers, at Manchester Polytechnic Library, on a trial subset of the British National Bibliography (BNB) data base on both CD-ROM and on-line. Various measures of search effectiveness and effiency were examined in relation to the effect of the differing user interface, including recall, precision, search time, user satisfaction and other more subjective factors. Discusses the potential for further research on the evaluation of CD-ROM.

- Abstract
- The purpose of this study is to obtain information which would help planners of the online catalog design a catalog which would be relevant to the needs of university faculty. Data was obtained by means of a questionnaire mailed to the faculty, College of Humanities, University of Utah. It was found that (1) references in books or articles they read; (2) the Subject Catalog; and (3) printed indexes, bibliographies and research guides in that order were the three most utilized information sources. Browsing was an important fourth. The faculty would like more in-depth coverage of the local library collection rather than access to other library catalogs or online databases from the catalog terminal. Feedback and comments in response to an open-ended question varied.

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
