    Abstract
    I(nvestigates the constituents of a good research task, requiring students to construct meaning from a variety of resources. The study involved collaboration between a high school media specialist, 7 teachers, and a university faculty member in Michigan, USA. 6 research projects involving 387 students of all ability levels were observed to identify elements associated with meaningsful research. Data were collected from a questionnaire completed by all students and student and teacher interviews. elements found to be related to satisfaction with the research process and to satisfaction with achievement were: student choice of topic, group work, course related topics, clarity of goals and means of evaluation, and process instruction

    Abstract
    Reports results of a questionnaire survey, the main purpose of which was to study and understand library users' perceptions of reference librarians' body language and its influence on the users' satisfaction of the reference interviews. The aim was to improve the overall quality of reference services. The study was undertaken in the National Yang-Ming University Library and involved 162 data samples. Describes the statistical methods used and the content analysis applied to the analysis of the data. Findings indicate that users prefer librarians' to adopt an approachable mode: arms relaxed; frequent eye contact; greeting users with a smile; hands unoccupied, and with appropriate hand gestures. Contrarily, preoccupation mode: with arms crossed; frowning; and hands busy with work; conveys an unfriendly message to library users. Concludes that the findings could be a valuable tool for reference librarians to develop their interviewing techniques in terms of body language and so improve the quality of referecne services

    Abstract
    Librarians at the University of the Pacific, California (UOP) designed a replication of an earlier transaction log study carried out at Adelphi University, New York (LRTS 38(1994) no.3, S.293-305). It was hypothesized that library staff would use a feature that allows the searcher to limit a search by location or material type more often than users. It was also hypothesized that library staff and reference librarians would have a higher success rate than public users. The third hypothesis was that UOP users would perform keyword searches more often than library staff. Studies were conducted in 1995 in 1996 to test these hypotheses to provide comparative data on the search styles of users and staff. Searches of the INNOPAC database, using transaction logs, were performed by 4 terminal groups: public users, technical services staff, public services staff, and reference librarians. It was discovered that replicating a study is not nearly as straightforward as was initially thought. It was also found to be surprisingly difficult to compare year to year data at the same institution; primarily due to a continually changing technological environment

    Abstract
    Identifies and characterizes the knowledge used by experienced librarians while searching for subject information in online catalogues. 10 experienced librarians performed the same set of 6 subject searches in an online catalogue. Investigates the knowledge used to solve retrieval problems. This knowledge presents expertise in the use of the catalogue. Data were collected through the use of think aloud protocols, transaction logs and structured interviews. Knowledge was defined as knowledge objects (factual knowledge), knowledge of events (experimental knowlegde), knowledge of performance (process knowledge), and metaknowledge. Metaknowledge is the sense of whole derived from the integration of factual, process, and experimental knowledge about the search and the conditions under which it is performed. Focuses on metaknowledge. For evidence of metaknowledge the data were examined for explanations that participants gave for their actions and observations, and for ways that participants evaluated their own progress during the process of searching. Reasons and explanations given by searchers were related to all phases of the library information retrieval process from the user's receipt of material to policies for collection development, and not just events directly related to the performance of a particular search task

    Abstract
    Many information channels are available to students, but it is now clear how students select and use them. Reports results of a study of the information seeking behaviour of students at 2 US universities: the American University; and the District of Columbia University. The study aimed to investigate: the information channels used by students when they work on course related projects and how they select the channels; how they use ALADIN, an augmented OPAC that provides access to the holdings of the Washington Research Library Consortium and several commercial online databases; and how selected characteristics of students are related to their use of information channels. Students identified convenience and quality of data as the top 2 factors in their choice of information channel. Affirms the value of librarians and of formal information channels, suggests ways to augment the online catalogue, and reminds librarians that equal access to information technology does not necessarily lead to equal use

    Abstract
    Reports a study of 40 audiotaped reference interactions between librarians and public library users. Analyzes the data to identify patterns of interaction, with a focus on users' problem formulation, librarians' elicitation of information from the user, unsolicited information provided by the users and the effect of these factors for the outcome of the interaction. Compares the results with studies of public library user behaviour in unassisted online catalogue searches. Users' initial query formulations are similar in the 2 situations. In the mediated searches, ambiguities are resolved and users' information needs are determined while interacting with the material on the shelf. Replication of this functionality in the online catalogue's interaction with the user would solve many problems in unassisted end user searches

    Abstract
    Describes an attempt, by Illinois University at Chicago (IUC) Library to respond to user needs as they are revealed in transaction logs of OPAC use. Illustrates success in improving access to catalogue records through a reengineering process. Outlines the IUC Library Reengineering Project, the administrative structure to study transaction logs, and the resultant managerial decisions. Notes the changes made to sreen display and to the OPAC. Focusing on customer satisfaction, IUC catalogue librarians joined forces with colleagues to identify Usrs' unmet needs and preferences through transaction log analysis. In order to minimize mismatches between users' expectations and services actually provided, IUC catalogue librarians studied logs and adjusted the OPAC. Descrinbes the specific efforts to increase access to the library's collections and the steps taken to enhance and customize bibliographic and authority records. Concludes that transition log analysis has enabled IUC to alter the form and content of its OPAC to fit the changing needs of diverse and widely disoersed users

    Abstract
    Reviews studies of users of OPACs focusing on the research methodology of librarians. Surveys and questionnaires, interviews, observation, controlled experiment and transaction log analysis were used with varying degrees of expertise and success in academic public libraries with a variety of user populations. Poor methodology due to lack of training and funding sharply limit their usefulness in most cases

    Abstract
    Over a 2 year period, the Getty Information Institute (formerly the Getty Art History Information Program) sponsored and carried out a major study of end user online searching by humanities scholars. Complete logs of the searches and output were captured, and the 27 scholars involved were interviewed in depth. Reviews the study and its results, with particular emphasis on matters of interest to academic librarians. Implications are drawn for academic library reference service and collection development, as well as for cataloguing in the online and digital environment

    Abstract
    Observes that whether in academic, special, or public libraries or on commercial online systems, CD-ROM, the online catalogue, or the Internet, certain end user errors crop up repeatedly. Details the main errors, which include input errors, errors arising from confusion in the face of different interfaces and screen designs, Boolean logic errors, term errors, conceptual errors, and errors due to the fact that users do not read instructions. Concludes that systems must solve the trivial errors automatically, but user instruction librarians must help solve the more complex problems

    Abstract
    Since the closing of the Sterling C. Evans Library author/title card catalog on march 6, 1989, librarians have observed a number of patrons who continued to use that catalog, even though NOTIS, the OPAC offered more comprehensive and current access to library holdings. To determine the reasons for this use, the authors prepared a one-page questionnaire, focusing on the users' preference for an inadequate card catalog in an environment which offers a superior OPAC. Card catalog patrons were then surveyed in order to gather data and build a user profile. Survey results were tabulated and analyzed, revealing the underlying reasons for users' preference for the card or online catalog. Conclusions will provide direction for improvements in users' access to online catalogs

    Abstract
    As more sophisticated searching capabilities become available on OPACs, librarians must wonder whether providing them is worthwhile. In order to determine whether users and nonusers of capabilities such as keyword and Boolean searching actually know how to use them properly, a survey was conducted of users of the NOTIS in Indiana State University Library. Results show a low degree of knowledge about keyword searching and points to the need for a built-in, easily used capability that does not require users to learn all the difficult precepts to be paid to automated aids to determining correct terminology for searching

    Abstract
    At the start of the academic year reference staff are hard pressed to provide sufficient assistance to first time users of CD-ROMs, who have missed bibliographic instruction classes, or who need more guidance before searching. The literature on CD-ROMs was reviewed, and a survey conducted to estimate the training needs of searchers. It was found that 100% of the inexperienced searchers required assistance while searching, and 50% of their search strategies were later rated as poor. More than half the experienced searchers also needed the librarians assistance, and 31% of this group demonstrated a poor understanding of searching techniques. The survey findings were incorporated into CDIntro, a computer assisted learning package designed by the authors

    Abstract
    The project explored the ways in which the online catalogue contributes, or does not contribute to the success of library users. Key issues examined included: whether students are really getting appropriate assistance when using the online catalogue; the most common searching successes and failures observed for people using the online catalogue without staff assistance; and the effectiveness of online catalogue use by librarians providing reference assistance compared to other sources (reference books, electronic and printed indexes). Reviews relevant studies of online catalogues and reference success and describes the methodology and results of 3 different online catalogue studies: the Reference Assessment Survey; the online catalogue study of unassisted users; and the document availability study; all conducted at San José State University Library; California, using the Reference Transaction Assessment Instrument. Considers the implications of the results for reference practice and study methodology

    Abstract
    Examines the searching behaviour of Guardian journalists searching FT PROFILE online system. Using transactional log analysis compares the searching styles of journalists with those of Guardian librarians. In some respects end users conform to the picture that professionals have of them - they search with a very limited range of commands - but in other respects they confound that image - they are very quick and economical searchers. Their behaviour relates to their general information seeking behaviour, and their searching styles would be seen in this regard
