    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
    In the summer of 2008 all University of North Carolina libraries switched from a traditional library catalog interface supporting text-based searching (TextOnly) to a text and facet-based interface (TextFacet) to improve users' search experiences. This study seeks to understand the differences between these two interfaces and how they affect the search experience of the novice user. In this study, 40 participants were asked to search for resources using both interfaces. Their search times and accuracy were measured across three types of search tasks (known, partially known, and exploratory). After completing the searches, they were asked a series of questions about their experiences. The data were analyzed in order to identify strengths and weaknesses in both search interfaces. Thirty-six out of 40 participants preferred the TextFacet interface to the TextOnly interface. Using three dependent variables-time, accuracy, and rating-the two interfaces were compared and interactions were tested with the three task types. Search times for the TextFacet were shorter and participants preferred the TextFacet search interface over the TextOnly search interface. Performances across the three task types were different in terms of search time. The partially known and exploratory task types showed similar distributions for rating and accuracy. These distributions were distinctly different from the known task type. The results of this study may assist libraries in developing improved library catalog search interfaces that utilize facets as well as text searching.

    Abstract
    In this study, Texas A&M University faculty and graduate students from 16 departments completed a survey about their methods of finding videocassettes in the library, how they searched the online catalog LibCat for videocassettes, and their perceptions of catalog record elements. Results demonstrated that the majority of respondents used LibCat the most often for finding videocassettes. They searched by title and were satisfied with known item searching. Finally, respondents considered authors of original works, actors, and directors as useful to both search and view in LibCat, while few perceived editor, consultant, and camera person as useful.

    Abstract
    Presents some results from research into the uses and usefulness of electronic bibliographic databases in academic contexts, carried out as part of a British Library funded research project. Ethnographic and focus group data was gathered initially in 3 departments (natural science, social science and humanities) at the University of Kent at Canterbury covering all academic staff, researchers and postgraduates. This was then expanded to postgraduates and staff in the same 3 disciplines at other universities. 5 themes from this research are outlined: who uses the system, who does not, and where are these activities and inactivities happening; where does formal training occur; and where does learning occur. The problems of interface between computer systems and users often mirrored that between library enquiry staff and users where users did not know to frame questions and the advice given was not in a form understood by the users

    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
    Describes an investigation of attitudes to the LION (Library Integrated Online Network) online public access catalogue at Liverpool Polytechnic Library (now Liverpool John Moores University) using observation and a questionnaire survey of 55 library users. The reaction to the automation of the library catalogue was positive and it appears to have improved service to users but more user education and guidance would result in a further improvement

    Abstract
    Three different interfaces for online public access catalogues were evaluated using transaction logging as a methodology. In two cases exercises were set and run against each interface so that results could be critically evaluated to indicate areas of weakness. In all cases a random transaction log was derived and this was used to diagnose system problems and identify patterns of behaviour. Results showed that searches were often difficult to categorise, users employing different approaches to the same end. Users also were prepared to undertake sustained searching until something was retrieved; however they then frequently stopped. Search input problems are also identified and possible areas for further research suggested

    Abstract
    NORDINFO financed project to evaluate OPACs from the end user's viewpoint began in Aug 91 and was aimed at discovering how different types of users carry out searches; how the different methods of describing a publication's contact are used; and evaluating how title, thesauri words and free text are combined in searching using the transaction log analysis method over a 6 week period. The results show that not even menus give enough guidance to an occasional user; free text searching was the most popular method; scan commands proved not popular. The number of searches retrieving no-references was similar in all libraries, while libraries differed in the truncated search terms. Multilingualism was a serious problem in all the online catalogues. Lists recommended improvements

    Abstract
    In a 1990 study of 5 different online public access catalogue (OPAC) systems at 5 Ontario university libraries, 2916 undergraduates, graduates and faculty were interviewed to determine their satisfaction with the computerised catalogue. Presents the results for the entire sample as well as the findings for each OPAC/site. Sets out 6 major findings and makes several recommendations for future research involving OPACs
