    Abstract
    The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

    Abstract
    Describes a project which monitored electronically 11 public access terminals, at the Colorado University Librarys, to produce transaction logs that were used to gather statistics and analyze the behaviour of users when searching the library online catalogues. The study recorded user behaviour unobtrusively and focused exclusively on what actually occured during the search process. Among other findings it was revealed that the use of system supplied search aids varied, from low use of quick search and express search features, to more extensive use of search history and searching databases other than the home catalogue. Analysis of search results revealed that 66% of subject (keyword) and name searches produce 10 or fewer results, and 82% produce 25 or fewer titles, a manageable number for searchers to scan postings and spot relevant materials. User persistence in scanning titles was found to be high with the full list being requested for nearly 40% of searches netting up to 100 results. Overall, results show that emphasis on improved system design must be stressed if the needs of the majority of searchers are to be met more effectively

    Abstract
    This article describes the findings of a research project that tested a new subject-access design in an experimental online catalog that had a wide range of subject-searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Library users at 2 academic libraries searched this experimental catalog for topics of their own choosing, judges the usefulness of retrieved titles, and answered post-search questions about their searching experiences. Mixed results from a quantitative analysis (i.e., precision scores) were supplemented with the more conclusive results from a qualitative analysis (i.e., failure analysis). Overall, analyses demonstrated that the new subject-access design that featured search trees was more effective in selecting a subject-searching approach that would prooduce useful information for the subjects users seek than users would select on their own. The qualitative analysis was especially helpful in providing recommendations for improving specific subject-searching approaches to increase their effenciency, increase user perseverance, and encourage browsing. It also suggested enhancements to the new subject-searching design to enable systems to respond to the wide variety of user queries for subjects

    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
    This paper reports the results of a survey of information needs and information seeking behaviour of a national sample of the UK population. The survey was the first stage of the Citizenship Information project, funded by the British Library Research and Innovation Centre. In total, 1294 responses were received giving a valid and demographically representative response rate of 45.7 per cent. Major findings include: that the majority of respondents had sought information in the past (59.4 per cent) and that an even greater number predicted a future need for information (78.4 per cent). Over three quarters of respondents said that they would use public libraries and between half and three quarters would approach Citizens Advice Bureaux, Post Offices, Government departments or family and friends. Face-to-face communications and reading a book were the most popular means of accessing information, but a wide variety of other preferred options were cited. Only a small proportion expressed a preference for using a computer to seek information, and there was a clear emphasis on public libraries as an appropriate location for accessing electronic information. A highly significant majority (79.2 per cent) believed that access to information was very important for exercising their rights as a citizen.

    Abstract
    Examines sex differences in library anxiety, computer anxiety and using computers for library research anxiety in 40 academically oriented high school seniors for 1 year. Finds boys to have higher library anxiety than girls. Girls have a higher anxiety in the remaining 2 categories involving computers. Both sexes improved in all 3 areas except for girls on the computers for library research. Girls may experience less anxiety when using computers in a non mathematical setting but the detrimental effect of computers may compromise girls' attitudes to computer mediated library research

    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
    A survey of catalogue use in 1993 at Utrecht University in the Netherlands showed considerable dissatisfaction with the online catalogue's subject search facilities. Of those who used subject searching 64% preferred subject headings against only 2% who chose classification schedules. Library users make little use of the existing facilities for assistance and leaflets which are available in the library. It has, therefore, been decided to provide a programme of instruction in library use and to move towards a unified system of subject access to the library's catalogue

    Abstract
    Reports an investigation to compare the various forms of catalogue available in Liverpool City Libraries and Liverpool John Moores University Library. The information was gathered through interviews with 52 lecturers and students at Liverpool John Moores university. The interview questions were concerned with the use of the library catalogues which were available, the effects of the online public access catalogue (OPAC) on searches, the effects of previous experience of an OPAC and catalogue preference. Nearly all the library users interviewed had used the OPAC. Many of them had changed the way in which they searched for references. The majority preferred the OPAC and did not continue to use the microfiche catalogue

    Abstract
    Analyses the technical features of the 5 main search fields of the OPAC run by Bologna University's interlibrary centre (CIB), part of the National Library Service (SBN). The CIB links about 100 academic and civil library collections on the humanities, social sciences, and science subjects. With the aid of Home Page / Helpline displays, examines how OPAC search procedures are carried out by author, title, subject, ISBN, or single library. Also explains the data filtering methods used. The CIB will soon broaden its OPAC search strategies by adopting the Florence University library OPAC research structure

    Abstract
    Data from Westminster Libraries on membership, borrowing frequency and stock use is compared with significant studies of public library use from the last 50 years. The article examines the extent of public library use, and the social and demographic factors influencing use. Analysis of book and audio-visual stock use indicates the concentration of demand on a few titles and subjects, and the relationship to what is in demand commercially. Aspects of public library use have remained constant over at least the last 50 years, and across geographical boundaries. Public libraries are used principally for leisure, for borrowing recent fiction, for useful non fiction related to immediate life interests, and for pop music. Quantitative data from library systems provides a different, probably more accurate, picture of the nature and extent of public library use.

    Abstract
    This paper reports findings from Phase I of the Wynnewood Study - a major project investigating the information-seeking and information needs of lowincome African-American households in the Wynnewood Project in Dallas, Texas. The Parks at Wynnewood is a residential housing development at which the University of North Texas (UNT) is currently conducting the Healthy Neighbourhoods urban revitalization project. This study is also part of the second phase of a major UNT project that is investigating the community service needs of the Wynnewood residents. During this needs assessment all Wynnewood households were interviewed using an extensive twelve-page questionnaire, including a number of questions on their information needs and information-seeking behaviour. The results of the survey provide data bearing on the development of an information resource center and an information literacy programme for Wynnewood community residents. A model of resident's information environment is presented. The study of information-seeking and information needs, also known as nonwork information-seeking or citizen information-seeking, is an important and emerging area of interdisciplinary information science research. More specifically, this study is providing important data on the everyday life information needs and seeking behaviours of low-income African Americans households.
