    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.

    Abstract
    As librarians evaluate the capabilities of online catalogs they will need to consider what information users expect to find in the catalog and what characteristics of the catalog will help users in their search for this information. The findings of studies concerning how library users actually use card catalogs and online catalogs, and their successes and failures in that use, can be used to determine the capabilities that are needed in anonline catalog to satisfy the bibliographic requests of library users

    Abstract
    Three studies were made of the use of COM catalogues at the University of Toronto and the Mississauga Library System: unobtrusive observations, structured interviews, and a timed-search experiment in reel, fiche and card catalogues. The reel catalogue was found to be the overwhelming favourite, almost as popular in the public library as in the academic library, where 82% of the users reported it to be their preferred form of catalogue. However, for nearly all test questions and searcher types in the timed-search experiment, successful searches required less time in the card catalogue than in either form of the COM catalogues.

    Abstract
    Reports results of a week long sample observation of card catalogue consultation by library users. Subsequent questioning of users about the purposes for which they consulted the catalogue revealed that the classified catalogue is not used as all and the author and title catalogue are consulted to the maximum. It is also found that 80% of the consultations of card catalogue are to locate documents, 10% is to make comprehensive searches for references on a topic and rest for miscellaneous purposes

    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
    Research on the use of online catalogs has challenged many assumptions about the behavior of library users. It has demonstrated that many of the patterns of behavior observed in the use of card catalogs were adaptions to the card technology; often behavioral patterns are different in an online environment. These studies have indicated that patrons prefer online catalogs and use them more, but they also show inadequacies in bibliographic practice, especially in the area of subject access.

    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 research project at Middlesex Polytechnic is examning the problems of subject access in an OPAC. A series of user studies have been carried out which examined students' use of existing catalogue facilities, which in turn led to the experimental evaluation of various interface designs for an online catalogue. The experiments were primarily concerned with the effect of the following variables on the speed and accuracy of retrieval of specific items, the use of colour, the speed of presentation of information, the amount of information on a screen, the paging and scrolling of information, the position of a sought item within a list

    Abstract
    Searching behaviour in a university library is studied using a holistic approach, encompassing the use of bibliographic tools and shelf browsing. The present study is designed as the first half of a 'before and after' study to permit the evaluation of the impact of a future online catalogue on users' searching behaviour. A combined methodology was devised: searchers were encouraged to talk aloud during their search, and this information, together with some probing and real time expert interpretation, enabled the experimente to record the searching activity on a highly structured observation form. The study reveals the extent of subject searching activity, and suggests that this may have been underestimated in previous studies. The analysis of expressed topics, search formulation strategy and documents retrieved reveals the adaptive nature of the subject searching process, whereby the user adapts to the structure of the available tools. The information retrieval task in a traditional library system is tailored by the system to a single, one dimensional, sequential process. It is suggested that a major obstacle to subject searching effectiveness may lie in the lack of interaction between the different possible approaches in the searching process: the indexing language, the classification, and the titles. It is to be hoped that a future online searching environment will encourage a more truly interactive approach to subject searching.
