    Abstract
    Arrowsmith, a computer-assisted process for literature-based discovery, takes as input two disjoint sets of records (A, C) from the Medline database. lt produces a list of title words and phrases, B, that are common to A and C, and displays the title context in which each B-term occurs within A and within C. Subject experts then can try to find A-B and B-C title-pairs that together may suggest novel and plausible indirect A-C relationships (via B-terms) that are of particular interest in the absence of any known direct A-C relationship. The list of B-terms typically is so large that it is difficult to find the relatively few that contribute to scientifically interesting connections. The purpose of the present article is to propose and test several techniques for improving the quality of the B-Iist. These techniques exploit the Medical Subject Headings (MeSH) that are assigned to each input record. A MesH-based concept of literature cohesiveness is defined and plays a key rote. The proposed techniques are tested an a published example of indirect connections between migraine and magnesium deficiency. The tests demonstrate how the earlier results can be replicated with a more efficient and more systematic computer-aided process.

    Abstract
    Informed citizens of all nations need to know how to find many forms of information, sift through and weigh it, and draw their own conclusions. Increasingly, access to information is tied to access to technology. In some parts of the world, a glut of information overwhelms and inundates. In other areas, information may be scarce and one-sided. Through information literacy instruction, people learn that information may appear in a variety of formats. They learn how to identify, locate, evaluate, and use information effectively and responsibly. Librarians and many others in government, business, and education can empower people through information literacy instruction and thereby help them become informed, critical thinking citizens. This next step beyond access to technology can take time, careful planning, attention to detail, support, and collaborative efforts among many different groups and individuals, including the learners themselves. The reward: An information literate populace, able to make informed decisions, based on a variety of carefully weighed evidence.

    Abstract
    The "teaching librarian" or "librarian as teacher" is a professional role that has been discussed in the literature of library and information science in recent decades, particularly in relation to bibliographic instruction and information literacy development. This paper reports on a small-scale research project, undertaken in 2002, that investigated the demand for library professionals with knowledge of or skills in instructional techniques and strategies. The project was based on an extensive literature review, plus content analysis of library and information science job advertisements on the international LIBJOBS listserv. The literature review has been updated for this BOBCATSSS paper, as have aspects of the content analysis, in order to provide delegates with more recent information. The idea of a teaching role for librarians is far from new. Michael Lorenzen (2002) has traced academic library-based instruction as far back as the seventeenth century when German academic libraries provided instructional programmes for library users. In academic and school libraries in the nineteenth century it usually took the form of "library orientation" - making sure that students and faculty knew how to find the books and other material for their courses. In the United States, some American university librarians were lecturing to students as early as the 1880s (Lorenzen, 2002). In nineteenth and early twentieth century public libraries, library instruction often took the form of literature promotion or reading promotion activities for children and young people, and even of "lessons" on how to look after books, right down to the need for washing hands before handling books. The introduction of card catalogues and classification systems such as the Dewey Decimal Classification resulted in a need for user education in all kinds of libraries, with sessions based on topics such as "The card catalogue: The key to the library" and "How to find a book on the shelves". The introduction of automated catalogues from the 1960s, and later, databases on CD-ROMs, online information services for end users, and the Internet, have increased the need and demand for formal and informal user education, regardless of the type and size of library. Indeed, there is no doubt that interest in library-based instruction has increased in recent decades: on the basis of an analysis of the literature related to the instructional role of librarians, Edwards (1994) noted that "during the past quarter century, interest and concern for library instruction has grown dramatically", while Marcum said in 2002 that "Over the past decade ... information literacy has emerged as a central purpose for librarians, particularly academic librarians".

    Abstract
    Purpose - This paper reports on a descriptive study undertaken to gain an overview of library and Information workplace needs (as of early 2002) for library professionals with knowledge and skills related to user education and information literacy instruction. Design/methodology/approach - A description and discussion of a small-scale research project that used content analysis techniques to study job advertisements posted to the international LIBJOBS listserv over a period of three months. Findings - A little over half of the advertisements required at least some experience of and/or skills in user education or instruction of some kind. Research limitations/implications - The analyses reported in this paper were carried out early in 2002. However, more recent literature, and more recent research reported elsewhere, indicate that the findings remain valid. Practical implications - The findings of the study, and recent literature, indicate that skills associated with user education and information literacy instruction are important in today's libraries. Originality/value - The paper focuses on demonstrable employer and workplace requirements for the LIS professional, rather than abstract formulations and discusses the resultant implications for librarians' continuing professional development and workplace learning.

    Abstract
    Purpose - This paper takes forward strands from "Evaluating the quality of library portals" by the author and places them in the context of different approaches to teaching students about information use. Design/methodology/approach - An opinion piece which examines the impact on user behaviour of traditional mechanical library skills training (such as "library orientation", "bibliographic instruction", or "information skills training" rather than true information literacy-based teaching). The paper points out the similarity in the effects of such teaching to the effects of offering users a more powerful mechanical information retrieval tool (such as a library portal or internet search engine) without effective support on how the information retrieved should be used for significant educational outcomes. Findings - For librarians to be custodians of the highest standards of intelligent information use, they must demonstrate a meaningful, rather than a mechanical understanding and application of information literacy in their everyday practice. Without this, information users will rightly turn to new, non-mediated forms of information use such as internet search engines, which can deal with purely technical challenges of information retrieval superficially well. Both the users and the profession itself will be the poorer as a result. Research limitations/implications - An expression of opinion about the dangers of pedagogically underdeveloped user education on user behaviour. Practical implications - This opinion piece gives some clear and practical insights for the application of information literacy principles to library practice. Originality/value - This piece points out the ironic similarities in the effect of a mechanistic or tool-based approach to user education and unmediated user access to internet search engines or Library portals: above all, a "more is better" approach in the information user, marked by citing too much poorly digested, poorly evaluated data.

    Abstract
    Purpose - This paper seeks to understand how users determine credibility in the internet environment from a conceptual level and the implications of these new methods of credibility determination on internet tools (primarily software) and services. Design/methodology/approach - The author first examines the underlying reasons for increased dependence on the internet for information, using electronic commerce as a starting point. The central concept of "information self-sufficiency" is introduced and then examined through the lens of the internet and conversation theory. Findings - The author finds that users are shifting from more traditional "authority" methods of credibility determination, where users cede determinations to trusted third parties, to a "reliability" approach where users seek commonalities and coherence among multiple information sources. This has led to an increased pressure for participation and openness at all levels of the internet. Research limitations/implications - Studies on users and credibility must better account for often invisible technical factors. Practical implications - Libraries must take into account a greater need for participation and technical fluency when dealing with patrons, particularly in information literacy programs and instruction. Originality/value - This paper presents a large-scale conceptual approach to credibility on the internet. It seeks to inform current approaches to the subject nested in communications and instruction with the unique technical environment of the internet.

    Abstract
    Purpose - This study seeks to apply ecological psychology's concept of "affordance" to graduate students' information behavior in the academic library, and to explore the extent to which the affordances experienced by graduate students differed from the affordances librarians were attempting to provide. Design/methodology/approach - In-depth, qualitative interviews with graduate students and academic librarians explored how the students perceived and used the library's various "opportunities for action" (e.g. books, databases, instructional sessions, librarians, physical space, etc.) and compared these perceptions and behavior with librarians' intentions and expectations. Findings - Findings indicate a disparity between expectations and experience and point to graduate students as an underserved population in this context, especially in terms of the library's outreach efforts. In addition, because graduate students are increasingly teaching introductory undergraduate courses, communication methods that bypass graduate students tend to miss undergraduate students as well. Practical implications - Practical implications discussed in this paper include possible methods of improving communication channels between graduate students and academic librarians, and considerations for information literacy instruction. Originality/value - This paper presents a unique perspective by using affordance theory to frame students and librarians' expectations about library services. The findings are particularly valuable for their implications for library-patron communication and information literacy.

    Abstract
    Purpose - In a 31-month period, 1,184 questions addressed to the Internet Public Library's (IPL) reference service remained unanswered on the grounds that they were "out of scope". This paper aims to analyze the questions as artifacts of users' expectations to better chart the distinction between user and librarian views of reference service. Design/methodology/approach - Each question is examined to identify two user expectations, i.e. what kinds of information librarians could provide and what kinds of needs librarians could help meet. Emergent coding with a code-recode rate of 97 per cent identifies 23 types of expected librarian assistance and 28 characteristics of expected applications of that assistance. Findings - Users expect IPL librarians to provide personal advice, analysis, facts, procedures, instruction, technology guidance and evaluation. IPL librarians are expected to help users in making decisions, solving problems, completing processes and developing understanding. Research limitations/implications - Limitations include the use of a single coder and the use of single institution's data set. Mapping these user expectations suggests a need for librarians to consider further development of reference service in terms of its judgment, form, and involvement parameters. Practical implications - Reference service policies and training should be examined to enhance librarians' abilities to consider judgment, form, and involvement parameters primarily from the user's perspective. Originality/value - This paper analyzes that which is rarely seen, i.e. e-mail reference questions which are considered beyond the scope of service. Additionally, the IPL question pool provides a broader range of user mental models than would be found in any geographically bound institution.

    Abstract
    Purpose - The purpose of this paper is to explore the applicability to information behaviour contexts of the notion of a "search image", a mental entity highlighted in a significant anthropological study appearing in the 1990s. Design/methodology/approach - The paper considers search images of information-seekers by exploring hypothetical situations and using source material pertaining to areas such as information systems, information retrieval, information-seeking and the nature of libraries. Findings - Two types of search image are postulated - those taking the form of a visual memory of a particular source and those providing a detailed specification of material required in a certain situation. Research limitations/implications - The definition of a search image presented here has not been evolved through research featuring specially-undertaken fieldwork. New studies, incorporating individual interviews or think aloud protocols, should be conducted in order to address a series of emergent questions relating to search images. Practical implications - When more has been learned about the characteristics of search images of successful information-seekers, it may be possible to build into programmes of information literacy prompts that will help individuals to clarify in their minds what they require before embarking on an information search. Originality/value - Intended for information practitioners and academics alike, the paper forms the first attempt to apply a particular concept originating outside the discipline, i.e. that of a search image, to information-seeking situations. Attention to search images has the potential to increase one's understanding of how individuals find information, as well as to add a further dimension to information literacy instruction.

    Abstract
    Purpose - Using a variety of evidence this paper aims to develop the concept of "inferential information-seeking". The term itself is new and the type of phenomena it addresses has been the subject of limited attention. Design/methodology/approach - The author considers inferential information-seeking in the context of three distinct scenarios, each of which has come to the writer's attention through either the literature or his own direct experience. Findings - Exploration of the identified instances of inferential information-seeking reveals that the strategy is a circuitous one employed by individuals when faced with barriers that impede their use of more obvious methods of finding information. Substantial mental effort may be required on the user's part to exploit the information elicited in such a way as to satisfy the information need stimulating the action. Research limitations/implications - The notion of inferential information-seeking postulated here is based on a very small number of cases, none of which has come to light in research specially undertaken to investigate the phenomenon. Practical implications - Even though knowledge of inferential information-seeking is still in its infancy, it would appear appropriate to incorporate some provision for it in the teaching of information literacy. Originality/value - Intended for information practitioners and academics alike, the paper synthesizes a new concept through examination of actual information-seeking episodes with reference to a wide-ranging body of source material. An understanding of inferential information-seeking offers the potential to increase our comprehension of how individuals find information, as well as to add a further dimension to information literacy instruction.

    Abstract
    This article focuses an analysing students' information needs in terms of conceptual understanding of the topic they propose to study and its consequences for the search process and outcome. The research subjects were 22 undergraduates of psychology attending a seminar for preparing a research proposal for a small empirical study. They were asked to make searches in the PsycINFO database for their task in the beginning and end of the seminar. A pre- and postsearch interview was conducted in both sessions. The students were asked to think aloud in the sessions. This was recorded, as were the transaction logs. The results show that during the preparation of research proposals different features of the students' conceptual structure were connected to the search success. Students' ability to cover their conceptual construct by query terms was the major feature affecting search success during the whole process. In the beginning also the number of concepts and the proportion of subconcepts in the construct contributed indirectly via search tactics to retrieving partly useful references. Students' ability to extract new query terms from retrieved items improved search results.
