    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
    Apart from information retrieval there is virtually no other area of information science that has occasioned as much resarch effort and writing as 'user studies'. Within user studies the investigation of 'information needs' has been the subject of much debate and no little confusion. The aim of this paper is to attempt to reduce this confusion by devoting attention to the definition of some concepts and by proposing the basis for a theory of the motivations for information-seeking behaviour

    Abstract
    One of the basic information-seeking activities where library users might experience information overload is scanning lists of references. Because much information seeking is discretionary - users may abandon a search without fear of penalty - lists that are too long may influence users to stop searching

    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
    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 objectives of the study were to conduct a series of observations and experiments under as real-life a situation as possible related to: (i) user context of questions in information retrieval; (ii) the structure and classification of questions; (iii) cognitive traits and decision making of searchers; and (iv) different searches of the same question. The study is presented in three parts: part 1 presents the background of the study and describes the models, measures, methods, procedures and statistical analyses used. Pt.2 is devoted to results related to users, questions, and effectiveness measures, and pt.3 to results related to searchers, searches, and overlap studies. A concluding summary of all results is presented in pt.3

    Abstract
    A set of methods and results is offered for characterizing how people make decisions in the course of using computerized databases. In general, their performance resembles that revealed in studies of decision making in other contexts. In particular, people are only moderately sensitive to the likelihood of their succeeding, being overconfident for all but the easiest of tasks. These results are discussed in the context of previous research in information science and decision science, and with regard to their implications for the design of databases and the adaptation of users to them

    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
