    Abstract
    This study aimed to determine if the searching behaviour of remote users of LIAS, Penn State's online catalogue differed from those using the OPAC within the library. More than 1.000 searches done by remote users (those accessing the system via either dial-access or the university's computer network) were compared to more than 1.000 searches done by in-house users. Each search was duplicated step by step and analysed according to a pre-determined set of criteria. Although few dramatic differences were found between the 2 groups, there were enough subtle differences to generate interest. In general, remote users are the more sophisticated searchers, bearing out the assumption that remote users seem to have a better conceptual knowledge of how an information system should operate. On the other hand, they struggle more with the procedural details of how to use the OPAC. Dial-access users seem to constitute a unique group of users: their searches are often quite different than those done by either network or in-house users

    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
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

    Abstract
    Patron queries at a four-year comprehensive college's online public access catalog were examined via transaction logs from March 2007. Three representative days were isolated for a more detailed examination of search characteristics. The results show that library users employed an average of one to three terms in a search, did not use Boolean operators, and made use of limits one-tenth of the time. Failed queries remained problematic, as a full one-third of searches resulted in zero hits. Implications and recommendations for improvements in the online public access catalog are discussed.

    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
    This article reports research that explored children's information retrieval behavior using an OPAC in an elementary school library. The study considers the impact of a variety of factors including user characteristics, the school setting, interface usability, and information access features on children's information retrieval success and breakdown. The study reports the overall patterns of children's behavior that influence success and breakdown in information retrieval as well as findings about the intentions, moves, plans, strategies, and search terms of children in grades one through six

    Abstract
    Explores the variety of user behaviour exhibited by users of information retrieval systems over time and the effort of differences between expert and novice searchers on an understanding of information searching dynamics and on the design of information systems. Based on a naturalistic case study. Points out some of the dynamic patterns of behaviour of children's use of online catalogues (OPACs)

    Abstract
    Discusses a multiple search session model of end users' interaction with information retrieval systems based on results from an exploratory study investigating end users' search sessions over time with OPACs or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted with 200 academic end users to investigate the occurrence of multiple search sessions

    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
    Summarizes findings of an international study on information-seeking habits and preferences: With extensive input from hundreds of librarians and OCLC staff, the OCLC Market Research team developed a project and commissioned Harris Interactive Inc. to survey a representative sample of information consumers. In June of 2005, we collected over 3,300 responses from information consumers in Australia, Canada, India, Singapore, the United Kingdom and the United States. The Perceptions report provides the findings and responses from the online survey in an effort to learn more about: * Library use * Awareness and use of library electronic resources * Free vs. for-fee information * The "Library" brand The findings indicate that information consumers view libraries as places to borrow print books, but they are unaware of the rich electronic content they can access through libraries. Even though information consumers make limited use of these resources, they continue to trust libraries as reliable sources of information.

    Abstract
    A research project at Middlesex Polytechnic is examning the problems of subject access in an OPAC. A series of user studies have been carried out which examined students' use of existing catalogue facilities, which in turn led to the experimental evaluation of various interface designs for an online catalogue. The experiments were primarily concerned with the effect of the following variables on the speed and accuracy of retrieval of specific items, the use of colour, the speed of presentation of information, the amount of information on a screen, the paging and scrolling of information, the position of a sought item within a list

    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
