    Abstract
    Paper presented at the 1992 IATUL seminar in Tallinn, estonia: 'Universal Availability of Publications in Science and Technology including those on the history and philosophy of grey literature' on UAP policy and practice. Discusses surveys conducted at the Helsinki Univ. of Technology Library analysing the use of the online catalogue. Covers the Internordic Study 'Monitoring the Online Catalogues of the Nordic Technical University Libraries', whose aim was the promotion of end-user accessibility to information as part of a training program. Users' search behaviour was observed during the course on the library's TENTTU information retrieval system. Analyses the transaction log files of end users. Presents statistics on the distribution of search elements in free text and field codes and the use of Boolean operators. Comments on a software package enabling analysis of the interaction between the system and the end user. This may be useful to evaluate training programs

    Abstract
    Current research on user interfaces to online public access catalogs is reviewed in an attempt to identify research methods and findings applicable to the design of effective user interfaces to online public access catalogs. A broad definition of user interface is employed which includes data structures, in addition to searching and indexing software. The following features of online public access catalogs are discussed: the demonstration of relationships between records, the provision of entry vocabularies, the arrangement of multiple entries on the screen, the provision of access points, the display of single records, and the division of the catalog into separate files or indexes. For each feature, user studies and other research on online public access catalogs are reviewed and those findings summarized which provide insight into user needs concerning that particular feature; issues are identified and directions for further research are suggested. Implications for cataloging codes and standards and system design are discussed

    Abstract
    Presents a state of the art review of the underlying theories of and analysis methods used to study the ways in which users (end users) receive and interpret information through information retrieval systems and looks at the potential for refining theories and adopting new analysis methods. Focuses on approaches that advocate the user centred perspective, including: the cognitive approach; and the holistic approach. Identifies and summarizes the significant studies and ideas since 1986 that are represented by these approaches and looks toward the design of more effective systems that are user oriented and incorporate features such as filtering that would provide retrieval results based on individual or group preferences. Concludes that systems designed from the user centred perspective would not only serve the intended audience but would further the user centred perspective of the entire information retrieval discipline

    Abstract
    This article discusses the major catalog use studies that have been conducted in the United States and Great Britain. The potential to influence the construction of new online public access catalogs is emphasized. The cumulative findings could serve as an information base which designers of OPAC systems could refer to in the course of their work

    Abstract
    Account of a limited experimental study at the Bibliothèque Publique d'Informations (BPI), the Paris multimedia public library, to establish a methodology for investigating user interactions with new technology. A wide range of materials are available at the BPI, including CD-ROMs and the Internet. Preliminary observations indicate that users do not follow the pattern dictated by the machine, but take approaches based on their own experience and skills. Setbacks are generally interpreted as defects in the software, not personla failure to master the system. Large scale qualitative abservation, using research methods from the social sciences, would establish a knowledge base for developing user skills to exploit multimedia resources more fully

    Abstract
    Reports on part of a study of real users' behaviour in selecting documents from a list of citations resulting from a search of an information retrieval system. Document selection involves value judgements and decision making. Understanding how users evaluate documents and make decisions provides a basis for designing intelligent information retrieval system that can do a better job of predicting usefulness

    Abstract
    Reports on the factor analysis of affective data gathered from a study of searching behaviour in 2 library catalogues. 20 subjects were assigned information problems to solve through searching a university card catalogue and 20 were assigned the same problems to solve in a comparable online catalogue. After searches were completed, subjects were asked to evaluate their search results and to respond to attitude measures about the search experience. The 11 attitude itmes were constructed to tap a variety of affective responses to the attitude measures. Factor patterns in the data can serve to identify the dimensions on which search experiences are evaluated by users, to direct further investigation into user evaluations, and to suggest features for inclusion in information retrieval systems accessed directly by users

    Abstract
    The design and implementations of online systems in libraries have proceeded without much demonstrated empirical understanding of the complexities of users' needs. Reports interviews with a group of humanist scholars at the Univ. of Pennsylvania about their experiences with the Research Libraries Information Network (RLIN) database. These interviews yielded a wide range of responses. 4 factors emerged consistently as significant determinants of use: content, connectivity, user-friendliness, and cost. Discusses and evaluates the significance of these factors, individually and in relation to one another

    Abstract
    Searching information retrieval systems is a highly interactive, iterative process that cannot be understood simply by comparing the output of a search session (the 'search product') to a query stated in advance. In this article, we examine evaluation goals and methods for studying information retrieval behavior, drawing examples from our own research and that of others. We limit our review to research that employs online monitoring, also known as transaction log analysis. Online monitoring is one of few methods that can capture detailed data on the search process at a reasonable cost; these data can be used to build quantitative models or to support qualitative interpretations of quatitative results. Monitoring is a data collection technique rather than a research design, and can be employed in experimental of field studies, whether alone or combined with other data collection methods. Based on the the research questions of interest, the researcher must determine what variables to collect from each data source, which to treat as independent varaibles to manipulate, and which to treat as dependent variables to observe effects. Studies of searching behavior often treat search task and searcher characteristics as independent variables and may manipulate other independent variables specific to the research questions addressed. Search outcomes, time, and search paths frequently are treated as dependent variables. We discuss each of these sets of variables, illustrating them with sample results from the literature and from our own research. Our examples are drawn from the Science Library Catalog project, a 7-year study of children's searching behavior on an experimental retrieval system. We close with a brief discussion of the implications of these results for the design of information retrieval systems

    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
    Examines the development of OPACs of the last 15 years and how this has promoted the use of automated information retrieval systems. Investigates how end users use the system available to them and the type of subject searches which they carry out. Compares 2 techniques for mapping searches. Concludes that there is a need for effective diagnosis and monitoring methods and an efficient method of analysis of end user use is essential

    Abstract
    The research described in this article extends work done on human behavior in naming concepts and objects by adapting a methodology developed at Bell Labs and applying it to a library indexing language, the Library of Congress Subject Headings. The study investigated the representation of users' knowledge (names of objects and concepts), database representation for similar objects and concepts, and degree of agreement among users and between users and information systems. Three user groups give names to 40 stumuli. Names generated were compared with each other and with LCSH. Degree of agreement was calculated using similarity measures. The analyses identified patterns of agreement and variability in naming. There was little agreement in the names people use and the names recommended for use by LC, implying that retrieval systems should do more to accomodate common naming behavior

    Abstract
    The searching behaviour of 79 end-users of CD-ROM databases was studied at the UCLA campus libraries. The results indicate that users lack basic knowledge on how to search and consequently their searches are not effective despite their efforts. Users therefore need help through training but most importantly by improving the CD-ROM user interfaces and retrieval systems

    Abstract
    Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

    Abstract
    This research investigated the ways in which different levels of knowledge about a topic can affect searching for information on that topic in a library online catalog. It was found that people with high levels of knowledge use more search expressions, including more general and nonproductive expressions, than low-knowledge users. It was also found that high-knowledge users employed more search expressions that had not been contained in their statements of information need than low-knowledge users. These differences in vocabulary use and search expression formulation may be of interest to designers of online catalogs as they attempt to increase the responsiveness of catalog systems to the needs of individual users

    Abstract
    Reports from a study investigating the extent to which academic end users conduct multiple search sessions, over time woth OPAC or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted using a questionnaire with 200 academic end users at Rutgers University Alexander Library, NJ and University of North Texas, to investigate the occurrence of multiple search sessions. Results show that at the time of the survey interview, 57% of end users had conducted multiple search sessions during their research project and 86% of end users conducted their 1st search session at the beginning stage of their information seeking process. 49% of end users had conducted between 1 and 6 search sessions and 8% more than 6 search sessions. 70% of multiple search sessionss end users had modified their search terms since their 1st search session. Discusses the implications of the findings for end user training, information retrieval systems design and further research

    Abstract
    Reports selected results from a large study, conducted at Rutgers University, NJ, which observed, under real life conditions the interactions between users, intermediaries and information retrieval systems before and during online searching. Examines the stages of the search process at which search terms from different sources were selected and how the search terms selected at different stages of the search process contributed to the retrieval of relevant items as judged by users. Notes the sequences in which terms were selected and analyzes the sequences to determine the types and frequencies of changes that occur in such sequences. Results indicate that there are regular patterns in search term selection during the online search process. Discusses the implications of these findings
