    Abstract
    Given that time is money, Web searching can be a very expensive proposition. Even with the best search technology, the usefulness of search results depends on the searcher's ability to use that technology effectively. In an effort to improve this ability, our research investigates the effects of logic training, interface training, and the type of search interface on the search process. In a study with 145 participants, we found that even limited training in basic Boolean logic improved performance with a simple search interface. Surprisingly, for users of an interface that assisted them in forming syntactically correct Boolean queries, performance was negatively affected by logic training and unaffected by interface training. Use of the assisted interface itself, however, resulted in strong improvements in performance over use of the simple interface. In addition to being useful for search engine providers, these findings are important for all companies that rely heavily on search for critical aspects of their operations, in that they demonstrate simple means by which the search experience can be improved for their employees and customers.

    Abstract
    Describes an experiment in which secondary students from 6 schools on the island of Oahu, Hawaii, were tested for their ability to interpret and construct search statements in a presearch activity. Students read brief instructions on concept analysis, Boolean operators, and search statement format. One group used a worksheet. A 10item quiz tested students' knowledge of term selection and search logic and obtained self confidence ratings after answering each question. Search statements were analyzed according to a typology of search statement errors. On average, each student made 2 errors per search statement. Students with higher self confidence ratings had significantly higher scores on all measures

    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
    The Getty Art History Information Program carried out a two-year project to study how advanced humanities scholars operate as end users of online databases. Visiting scholars at the Getty Center for the History of Art and the Humanities in Santa Monica, CA, were offered the oppotunity to do unlimited subsidized searching of DIALOG databases. This second report from the project analyzes how much searching the scholars did, the kinds of search techniques and DIALOG features they used., and their learning curves. Search features studied included commands, Boolean logic, types of vocabulary, and proximity operators. Error rates were calculated, as well as how often the scholars used elementary search formulations and introduced new search features and capabiblities into their searches. The amount of searching done ranged from none at all to dozens of hours. A typical search tended to be simple, using one-word search terms and little or no Boolean logic. Starting with a full day of DIALOG training, the scholars began their search experience at a reasonably high level of competence; in general, they maintained a stable level of competence throughout the early hours of their search experience

    Abstract
    This paper presents a detailed analysis of the structure and components of queries written by experimental participants in a study that manipulated two factors found to affect end-user information retrieval performance: training in Boolean logic and the type of search interface. As reported previously, we found that both Boolean training and the use of an assisted interface improved the participants' ability to find correct responses to information requests. Here, we examine the impact of these training and interface manipulations on the Boolean operators and search terms that comprise the submitted queries. Our analysis shows that both Boolean training and the use of an assisted interface improved the participants' ability to correctly utilize various operators. An unexpected finding is that this training also had a positive impact on term selection. The terms and, to a lesser extent, the operators comprising a query were important factors affecting the participants' performance in query tasks. Our findings demonstrate that even small training interventions can improve the users' search performance and highlight the need for additional information retrieval research into how search interfaces can provide superior support to today's untrained users of the Web.

    Abstract
    Purpose The purpose of this paper is to investigate the relationship between preferred choice of school subject and student information behaviour (IB). Design/methodology/approach Mixed methods were employed. In all, 152 students, teachers and librarians participated in interviews or focus groups. In total, 1,375 students, key stage 3 (11-14 years) to postgraduate, responded to a questionnaire. The research population was drawn from eight schools, two further education colleges and three universities. Insights from the literature review and the qualitative research phase led to a hypothesis which was investigated using the questionnaire: that students studying hard subjects are less likely to engage in deep IB than students studying soft subjects. Findings Results support the hypothesis that preferences for subjects at school affect choice of university degree. The hypothesis that a preference for hard or soft subjects affects IB is supported by results of an analysis in which like or dislike of maths/ICT is correlated with responses to the survey. Interviewees' comments led to the proposal that academic subjects can be classified according to whether a subject helps students to acquire a "tool of the Mind" or to apply such a tool. A model suggesting how IB may differ depending on whether intellectual tools are being acquired or applied is proposed. Practical implications The "inner logic" of certain subjects and their pedagogies appears closely linked to IB. This should be considered when developing teaching programmes. Originality/value The findings offer a new perspective on subject classification and its association with IB, and a new model of the association between IB and tool acquisition or application is proposed, incorporating the perspectives of both teacher and student.

    1. Introduction The title of this paper is taken from a TV show which has gained considerable popularity in North America: A Queer Eye for the Straight Guy, in which a group of gay men subject a helpless straight male to a complete fashion makeover. In facet analysis, this would probably be seen as an "operation upon" something, and the Bliss Bibliographic Classification would place it roughly two-thirds of the way along its facet order, after "types" and "materials," but before "space" and "time." But the link between gay communities and facet analysis extends beyond the facetious title. As Web-based information resources for gay and lesbian users continue to grow, Web sites that cater to, or at least refrain from discriminating against gay and lesbian users are faced with a daunting challenge when trying to organize these diverse resources in a way that facilitates congenial browsing. And principles of faceted classification, with their emphasis an clear and consistent principles of subdivision and their care in defining the order of subdivisions, offer an important opportunity to use time-honoured classification principles to serve the growing needs of these communities. If faceted organization schemes are to work, however, we need to know more about gay and lesbian users, and how they categorize themselves and their information sources. This paper presents the results of an effort to learn more.

    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.
