    Abstract
    How postings information is used for inverted file searching was investigated by comparing searches, made by postgraduate students at the Dept. of Information Studies, of the LISA database on CD-ROM with and without postings information. Performance (the number of relevant references, precision and recall) was not significantly different but searches with postings information took more time, and more sets were viewed, than in searches without postings. Postings information was used to make decisions to narrow or broaden the search; to view or print the references. The same techniques were used to amend searches whether or not postings information was available. Users decided that a search was satisfactory on the basis of the search results, and consequently many searches done without postings were still considered satisfactory. However, searchers thought that the lack of postings information had affected 90% of their searches. Differences in search performance and searching behaviour were found in participants who were shown to have different learning styles using the Witkin's Embedded Figures test and the Lancaster Short Inventory of Approaches to Learning Test. These differences were, in part, explained by the differences in behaviour indicated by their learning styles

    Abstract
    Reports results of an investigation, undertaken at Sheffield University, Departmant of Information Studies, UK into the effects of postings information (the display on the screen of the number of references in the retrieved sets) on searching behaviour. Linked online searches were conducted, on the LISA database on CD-ROM, with and without postings information. Performance in terms of the number of relevant references, precision and recall was not significantly different whether postings information was available or not; but searches with postings information took more time and more sets were viewed than in searches without postings. Searchers thought that the lack of postings information had affected 90% of their searches. Proposes that training should place greater emphasis on the value of postings information at different stages of the search and should optimize the searching behaviour of those with different searching styles

    Abstract
    Reports on a study conducted at Indiana University in the summer of 1993 which observed 10 advanced graduate students in language and literature studies as they conducted literature searches using databases on CD-ROM. Presents a brief review of related literature on relevance judgements, human-computer interaction (HCI) and information seeking behaviour of humanities students. The search strategies of the graduate students under study were found to be typical of humanities scholars, who create large sets and review records quickly to select relevant items. Factors influencing relevance assessments included language, source of publication, author, and length of work. Participants especially appreciated electronic access to the Modern Language Association (MLA) International Bibliography but encountered problems with the controlled vocabulary and analytic entries for books and proceedings. The study has identified problems with database content, presentation and search interfaces which should be considered by system designers

    Abstract
    Reviews work of the Getty Art History Information Program (AHIP), recently renamed the Getty Information Institute, where humanities scholars were trained in DIALOG online searching and then allowed 24 hour unlimited access to DIALOG searching and DIALOG databases and where complete transaction logs were taken to yield the data upon which the Getty Online Searching Project was based. Summarizes results of the study of this subsidized access which was reported in a series of papers by M.J. Bates, who found that searching patterns of humanities researchers differed substantially from previous studies in the sciences and social sciences disciplines. Presents a model of the relative merits and opportunities associated with the various contractual arrangements and incentive strategies employed by AHIP with vendors such as DIALOG, consortia such as the Research Libraries Group, and a CD-ROM publication programme, compared to print publications and the experimental offer of access to some of the AHIP databases over the WWW. The arguments are illustrated by means of 2 case studies, involving: changes in pricing of the Avery Index to Architectural Periodicals; and the Getty Online Searching Project

    Abstract
    Reports of a study in a Chilean university library, comparing 100 users of online databases and CD-ROMs with 100 users of non-computerized bibliographical resources. Results showed that users tended to be teachers / researchers, and potential users were postgraduate students. Comparison of search results showed online searching improved results and saved time. The chief reasons for non-use were ignorance of the service and use of own personal computer. The study indicated the need to review policy on database acquisition and improve promotion of the service. In general, librarians should motivate greater use of online searching by providing skilled intermediary services to maximize uptake

    Abstract
    Report of a study at the University of Montreal (Quebec) analysing research on the behaviour of children using information technology (online databases, CD-ROM, computerised catalogues). From a range of publications covering 6-12 year olds in the US, Canada, Europe and Oceania common features were identified: (1) children's cognitive development does not match the structured approach required for this type of information research, (2) the main abrriers were physical (e.g. using keyboard), intellectual (no capacity for abstract reasoning) and social (little access to computers); (3) in terms of natural skills, boys has greater abilities than girls. Results indicate the need to make technology more appropriate for children, and train libarrians to recognise the real capacities and limitations of children so they can teach them the basic skills

    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
    This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web
