    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 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
    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
    A survey was conducted during 1987 to identify how online catalog users interact with various aspects of the catalog's authority control structure. Questionnaires were sent to major online catalog system vendors and to selected university libraries and networks known to have developed in-house online catalogs; additional copies were distributed to ACIG meeting participants during the ALA conference in San Francisco, June 1987. Twenty-one usable responses were received, twelve describing commercially available systems and nine from lacally developed systems.

    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 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
    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
    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
    Research in user behavior on online catalogs is in its early stages, but preliminary findings suggest that users encounter many of the same problems identified in behavioral studies of other types of bibliographic retrieval systems. Much can be learned from comparing the results of user behavior studies on these two types of systems. Research on user problems with both the mechanical aspects and the conceptual aspects of system use is reviewed, with the conclusion that more similiratiy exists across types of systems in conceptual than in mechanical problems. Also discussed are potential sources of the problems, due either to individual characteristics or to system variables. A series of research questions is proposed and a number of potential interim solutions ae suggested for alleviating some of the problems encountered by users of information systems
