    Abstract
    Hypothesizing that workplace significantly affects information-seeking patterns, this study compared accessibility and use of information sources among 233 Israeli computer scientists and software engineers, employed in industry and academy, using a mail questionnaire, which yielded a usable reply rate of 33%. The two groups were found to differ significantly in age, education, seniority, and type of research they performed (basic vs. applied). Printed textbooks, professional journals, and oral discussions with colleagues or experts in the organization were common to both groups, topping almost all lists of accessibility and use. For most information sources, however, the two groups differed significantly and consistently. Printed professional journals as weIl as printed and electronic conference or meeting papers were consistently more accessible and more often used by the academy group, while the industry group reported greater access to and more frequent use of electronic textbooks and trade or promotional literature. In regard to handbooks and standards, in-house technical reports (printed), government technical reports (Internet), librarians and technical specialists (Internet), and oral discussions with supervisors, no significant differences in accessibility were found, but their use by the industry group was much higher. In both groups, accessibility was only partly related to use, and more so among the academy than the industry group.

    Abstract
    No prior research has been identified that investigates the causal factors for workplace exploratory search task performance. The impact of user, task, and environmental factors on user satisfaction and task performance was investigated through a mixed methods study with 26 experienced information professionals using enterprise search in an oil and gas enterprise. Some participants found 75% of high-value items, others found none, with an average of 27%. No association was found between self-reported search expertise and task performance, with a tendency for many participants to overestimate their search expertise. Successful searchers may have more accurate mental models of both search systems and the information space. Organizations may not have effective exploratory search task performance feedback loops, a lack of learning. This may be caused by management bias towards technology, not capability, a lack of systems thinking. Furthermore, organizations may not "know" they "don't know" their true level of search expertise, a lack of knowing. A metamodel is presented identifying the causal factors for workplace exploratory search task performance. Semistructured qualitative interviews with search staff from the defense, pharmaceutical, and aerospace sectors indicates the potential transferability of the finding that organizations may not know their search expertise levels.

    Abstract
    This longitudinal study examined the search behavior of 10 students as they completed assigned exercises for an online professional course in expert searching. The research objective was to identify, describe, and hypothesize about features of the behavior that are indicative of procedural knowledge gained during guided instruction. Log-data of search interaction were coded using a conceptual framework focused on components of search practice hypothesized to organize an expert searcher's attention during search. The coded data were analyzed using a measure of pointwise mutual information and state-transition analysis. Results of the study provide important insight for future investigation of domain-independent search expertise and for the design of systems that assist searchers in gaining expertise.

    Abstract
    Much of the research conducted into young people's information seeking has taken place in schools. These organisations afford access to hundreds of diverse youngsters. They are accessible, and pupils are effectively pre-classified for the researcher. Factors within a school that may affect information-seeking behaviour can be explored. Nevertheless, it can be difficult to secure all appropriate permissions for the work. The timing of data collection can be problematic and the pupil population may not include all groups of interest. The investigator must also decide on the method(s) used for collecting data from the youngsters. Several lend themselves to developing an understanding of how far the individuals under scrutiny use particular sources, systems or organisations. Others are more effective for exploring the strategies inquirers employ when exploiting materials. The investigator must select the method that appears best equipped to deliver a satisfactory answer to the research question.

    Abstract
    This second part of a two-part article establishes a model of the mediating factors that influence student information behavior concerning the electronic or digital information sources used to support learning. This part discusses the findings of the Joint Information Systems Committee User Behavior Monitoring and Evaluation Framework (1999-2004) and development of a model that includes both the individual (micro) and organizational (macro) factors affecting student information behavior. The macro factors are information resource design, information and learning technology infrastructure, availability and constraints to access, policies and funding, and organizational leadership and culture. The micro factors are information literacy, academics' information behavior, search strategies, discipline and curriculum, support and training, and pedagogy. We conclude that the mediating factors interact in unexpected ways and that further research is needed to clarify how those interactions, particularly between the macro and micro factors, operate.

    Abstract
    This two-part article establishes a model of the mediating factors that influence student information behavior concerning electronic or digital information sources that support their learning. The first part reviews the literature that underpinned the development of the research methodology for the Joint Information Systems Committee (JISC) User Behavior Monitoring and Evaluation Framework, as well as the literature that has subsequently helped to develop the model over the 5 years the Framework operated in the United Kingdom, in five cycles of research that were adjusted to meet the emerging needs of the JISC at the time. The literature review attempts to synthesize the two main perspectives in the research studies: (a) smallscale studies of student information behavior; and (b) the studies that focus on the quantitative usage of particular electronic information services in universities, often including implications for training and support. As the review indicates, there are gaps in the evidence concerning the browsing and selection strategies of undergraduate students and the interaction of some of the mediating influences on information behavior. The Framework developed a multimethod, qualitative and quantitative methodology for the continued monitoring of user behavior. This article discusses the methods used and the projectmanagement challenges involved, and concludes that at the outset, intended impacts need to be specified carefully, and that funding needs to be committed at that point for a longitudinal study. A research project on information behavior, intended to inform current policymaking on infrastructure provision, is inherently difficult as behavior changes lag behind provision.

    Abstract
    This study focuses on the task as a fundamental factor in the context of information seeking. The purpose of the study is to characterize kinds of tasks and to examine how different kinds of task give rise to different kinds of information-seeking behavior on the Web. For this, a model for information-seeking behavior was used employing dimensions of information-seeking strategies (ISS), which are based on several behavioral dimensions. The analysis of strategies was based on data collected through an experiment designed to observe users' behaviors. Three tasks were assigned to 30 graduate students and data were collected using questionnaires, search logs, and interviews. The qualitative and quantitative analysis of the data identified 14 distinct information-seeking strategies. The analysis showed significant differences in the frequencies and patterns of ISS employed between three tasks. The results of the study are intended to facilitate the development of task-based information-seeking models and to further suggest Web information system designs that support the user's diverse tasks.

    Abstract
    The Household Information Systems (HIS) project in Queen Margaret College was funded to explore the use of new media in a group of Edinburgh households (Davenport & Higgins, 1995). One of the motivations of the HIS 'programme' was to find a suitable theoretical and/or exploratory framework, which takes account of multiple aspects of behaviour surrounding technologies, and thus avoids assumptions about their role in information-seeking or other isolated activities. A focus on single activities would occlude knowledge of other motivations: bonding, killing time, defining boundaries. In Phase One, `information management' rather than `information seeking' was used as a conceptual framework, embracing work on the `life cycle' of ICTs as illustrated by Kopytoffs `biography of things' approach (1986), Johnson's cultural circuit (1986), research on households as micro-organisations by McCrone and his colleagues (1994), and work by Silverstone and others on ICTs in the home as tools for internal and external adaptation (Silverstone, 1994, Silverstone et al 1994). The `management' framework has been productive - Phase One allowed us to identify patterns of ICT acquisition and deployment in the home, and, more interestingly, structures of appropriation which reflect rules, roles and responsibilities in individual households. These constitute what may be called a `reproduction lattice' (adapting terminology used by Kling (1987) in his analysis of the `web of computing' in organisations), a structure which captures the political and cultural economy of a household. Phase One's findings are consistent with those of other researchers working in the area of domestic consumption of ICTs but a major limitation of the work is the homogeneous nature of the respondents. Among our Edinburgh 'household managers', internal culture was a more compelling explanation for use than technical functionality.

    Abstract
    The article reports a field study which examined the mental models of 80 undergraduates seeking information for either a history or psychology course essay when they were in an early, exploration stage of researching their essay. This group is presently at a disadvantage when using thesaurus-type schemes in indexes and online search engines because there is a disconnect between how domain novice users of IR systems represent a topic space and how this space is represented in the standard IR system thesaurus. The study attempted to (a) ascertain the coding language used by the 80 undergraduates in the study to mentally represent their topic and then (b) align the mental models with the hierarchical structure found in many thesauri. The intervention focused the undergraduates' thinking about their topic from a topic statement to a thesis statement. The undergraduates were asked to produce three mental model diagrams for their real-life course essay at the beginning, middle, and end of the interview, for a total of 240 mental model diagrams, from which we created a 12-category mental model classification scheme. Findings indicate that at the end of the intervention, (a) the percentage of vertical mental models increased from 24 to 35% of all mental models; but that (b) 3rd-year students had fewer vertical mental models than did 1st-year undergraduates in the study, which is counterintuitive. The results indicate that there is justification for pursuing our research based on the hypothesis that rotating a domain novice's mental model into a vertical position would make it easier for him or her to cognitively connect with the thesaurus's hierarchical representation of the topic area.

    Abstract
    This paper highlights some of the significant findings from author's PhD: "Factors affecting the end-use of electronic databases in public libraries." Public libraries have a wide range of different types of users who, unlike academic or special library users, are not necessarily information-trained (see Coles, 1998). Whereas the academic, special library user may have specific information needs that can be met by electronic sources, public library users do not necessarily have such specific information needs that can easily be identified and met. Most user surveys have tended to concentrate on the searching and retrieval aspect of information seeking behaviour, whereas this study's user survey focused more on how people perceived and related to Information and Communication Technologies (ICTs). It was not how people searched a particular electronic source, in this case CD-ROM, that was of prime interest but rather whether or not people actually used them at all and the reasons why people did or did not use electronic media. There were several reasons the study looked at CD-ROM specifically. Firstly, CD-ROM is a well established technology, most people should be familiar with CD-ROM/multimedia. Secondly, CD-ROM was, at the start of the study, the only open access electronic media widely available in public libraries. As well as examining why public library users chose to use electronic sources, the paper looks at the types of CD-ROM databases used both in the library and in general Also examined are what sort of searches users carried out. Where appropriate some of the problems inherent in studying end-users in public libraries and the difficulty in getting reliable data, are discussed. Several methods were used to collect the data. I wished to avoid limiting research to a small sample of library sites, the aim was to be as broad in scope as possible. There were two main groups of people 1 wished to look at: non-users as well as CD-ROM users

    Abstract
    Purpose - The study aims to examines two aspects of information seeking behaviour of physicists and astronomers including methods applied for keeping up-to-date and methods used for finding articles. The relationship between academic status and research field of users with their information seeking behaviour was investigated. Design/methodology/approach - Data were gathered using a questionnaire survey of PhD students and staff of the Department of Physics and Astronomy at University College London; 114 people (47.1 per cent response rate) participated in the survey. Findings - The study reveals differences among subfields of physics and astronomy in terms of information-seeking behaviour, highlights the need for and the value of looking at narrower subject communities within disciplines for a deeper understanding of the information behaviour of scientists. Originality/value - The study is the first to deeply investigate intradisciplinary dissimilarities of information-seeking behaviour of scientists in a discipline. It is also an up-to-date account of information seeking behaviour of physicists and astronomers.

    Abstract
    The history of user evaluation of reference service is traced and related to other methods of reference evaluation, including librarian self report of success, behavioral guidelines, and ubobtrusive observation. The evidence to be derived from presently available user evaluations is considered in the light of criteria for a reference evaluation instrument. Concludes that reference success cannot be explained by any one group of factors, and that the best evaluation will utilize many methods

    Abstract
    This study reports an analysis of referral URL data by the Cornell University IP address from the American Chemical Society servers. The goal of this work is to better understand the tools used and pathways taken when scientists connect to electronic journals. While various methods of referral were identified in this study, most individuals were referred infrequently and followed few and consistent pathways each time they connected. The relationship between the number and types of referrals followed an inverse-square law. Whereas the majority of referrals came from established finding tools (library catalog, library e-journal list, and bibliographic databases), a substantial number of referrals originated from generic Web searches. Scientists are also relying an local alternatives or substitutes such as departmental or personal Web pages with lists of linked publications. The use of electronic mail as a method to refer scientists directly to online articles may be greatly underestimated. Implications for the development of redundant library services such as e-journal lists and the practice of publishers to allow linking from other resources are discussed.
