    Abstract
    Reports on a study of the search tactics used in searching the WWW and in dealing with difficulties such as too many postings and no relevant postings. Describes how the study was carried out, the analytical techniques used in it, and the results. Notes that with regard to tactics used to address search difficulties, no differences were found between searchers for texts and those for graphic information, and between those for known items and subject searches. Comments on the similarities and differences between the tactics used and and those used in online searching, including online catalogue searching

    Abstract
    Past trends in reference instruction, query analysis and proloferation of reference tools classed by primary functions into a general typology anticipated the use of paradigm logic, templates, search strategies, and systematic searching in applied Artificial Intelligence research and design of expert system, especially referral and decision-support systems. The approach, methodologies, and technique employed in basic reference and subject-area reference instruction in four graduate library schools, developed first at the University of Maryland after 1976, are reviewed. The advantages and limitations of the latter are discussed to suggest the interplay of personal service, manual tools, and computerized systems for holistic reference programs. Librarians' transition to the automated tools using AI methods might be improved by introducing paradigms, typologies, strategies, and a systems approach in reference instruction for professionals and more generally in bibliographic instruction

    Abstract
    In information needs, seeking and use (INSU) research, individuals have most commonly been perceived as users (e.g., Kuhlthau, 1991; Dervin & Nilan, 1986; Dervin, 1989; Belkin, 1980). The concept user originates from the user of libraries and other information services and information systems. Over the years the scope of the concept has become wider and it is nowadays often understood in the sense of seekers of information (e.g., Wilson, 1981; Marchionini, 1995) and users of information (e.g., Streatfield, 1983). Nevertheless, the concept has remained ambiguous by being on the one hand universal and on the other hand extremely specific. The purpose of this paper is to map and evaluate views on people whose information behaviour has been in one way or another the core of our research area. The goal is to shed some light on various relationships between the different aspects of doers in INSU studies. The paper is inspired by Dervin's (1997) analysis of context where she identified among other themes the nature of subject by contrasting a `transcendental individual' with a `decentered subject', and Talja's (1997) presentation about constituting `information' and `user' from the discourse analytic viewpoint as opposed to the cognitive viewpoint. Instead of the metatheoretical approach applied by Dervin and Talja, a more concrete approach is valid in the present analysis where no direct arguments for or against the underlying metatheories are itemised. The focus is on doers in INSU studies leaving other, even closely-related concepts (i.e., information, information seeking, knowledge etc.), outside the scope of the paper.

    Abstract
    This study investigated the effects of subject knowledge and search experience on novices' and experienced searchers' use of search tactics in online searches. Novice and experienced searchers searched a practice question and two test questions in the ERIC database on the DIALOG system and their use of search tactics were recorded by protocols, transaction logs, and observation. Search tactics were idetified from the literature and verified in 10 pretests, and nine search tactics variables were operationalized to describe the differences between the two searcher groups. Data analyses showed that that subject knowledge interacted with search experience, and both variables affected searchers' behavior in four ways: (1) when questions in their subject area were searched, experience affected searchers' use of synonymous terms, monitoring of the search process, and combinations of serch terms; (2) when questions outside their subject areas were searched, experience affected searchers' reliance on their own terminology, use of the thesaurus, offline term selection, use of synonymous terms, and combinations of search terms; (3) within the same experience group, subject knowledge had no effect on novice searchers; but (4) subject knowledge affected experienced searcher's reliance on their own language, use of the thesaurus, offline term selection, use of synonymous terms, monitoring of the search, and combinations of search terms. The results showed that search experience affected searchers' use of many search tactics, and suggested that subject knowledge became a factor only after searchers have had a certain amount of search experience

    To be successful at online searching, students must be able to apply the concepts and skills learned in the classroom to a variety of complex products and search conditions. Examines an online searching instructional programme for high school seniors from the perspective of several cognitive learning theories, and proposes a synthesized approach to applying learning theory to bibliographic instruction

    Abstract
    Looks at bibliographic instruction in the age of electronic searching and the the need to provide instruction to insure that remote access to the library is successful. Outlines an approach to teaching library skills by Loomis and Fink in 1993, that is equally relevant to school and public libraries, in which they argue that a successful search can no longer be equated with the quantity of material retrieved but with its relevance. This is dependent upon standardisation of access points, search language and online instructions

    Abstract
    It is common to distinguish sharply between leisure reading undertaken purely for pleasure and utilitarian reading that satisfies what Peter Mann (1969, 53-61) has called `extrinsic' interests: reference materials for work and home such as medical books, cook books and repair manuals. We might suppose that information-seeking is concerned only with utilitarian reading. However, once we adopt a definition of information as something that fills in a gap in understanding or makes a difference to an individual's cognitive structure or helps people with their lives, it follows that we cannot deduce uses simply by looking at the texts themselves. Since meanings are constructed by readers, we must ask the readers about the uses they make of texts in the context of their lives. Findings from a research project focussed on 194 readers who read for pleasure indicate that for a broad understanding of the information behaviour of ordinary people, we need to think beyond reference books to include extended narrative forms, particularly biography, history, and fiction. People who are avid readers for pleasure report that during the course of wide reading they serendipitously encounter information that helps them in their lives

    Abstract
    Systematic reviews are becoming increasingly important for health care professionals seeking to provide evidence based health care. In the past, systematic reviews have been difficult to identify among the mass of literature labelled 'reviews'. Reports results of a study to design search strategies based on a more objective approach to strategy construction. MEDLINE was chosen as the database and word frequencies in the titles, abstracts and subject keywords of a collection of systematic reviews of the effective health care interventions were analyzed to derive a highly sensitive search strategy. 'Sensitivity' was used in preference to the usual term 'recall' as one of the measures (in addition to the usual 'precision'). The proposed strategy was found to offer 98% sensitivity in retrieving systematic reviews, while retaining a low but acceptable level of precision (20%). Reports results using other strategies with other levels of sensitivity and precision. Concludes that it is possible to use frequency analysis to generate highly sensitive strategies when retrieving systematic reviews
