    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
    Purpose The current understanding of serendipity is based primarily on studies employing westerners as the participants, and it remains uncertain whether or not this understanding would be pervasive under different cultures, such as in China. In addition, there is not a sufficient systematic investigation of context during the occurrence of serendipity in current studies. The purpose of this paper is to examine the above issues by conducting a follow-up empirical study with a group of Chinese scholars. Design/methodology/approach The social media application "WeChat" was employed as a research tool. A diary-based study was conducted and 16 participants were required to send to the researchers any cases of serendipity they encountered during a period of two weeks, and this was followed by a post-interview. Findings Chinese scholars experienced serendipity in line with the three main processes of: encountering unexpectedness, connection-making and recognising the value. An updated context-based serendipity model was constructed, where the role of context during each episode of experiencing serendipity was identified, including the external context (e.g. time, location and status), the social context and the internal context (e.g. precipitating conditions, sagacity/perceptiveness and emotion). Originality/value The updated context model provides a further understanding of the role played by context during the different processes of serendipity. The framework for experiencing serendipity has been expanded, and this may be used to classify the categories of serendipity.

    Abstract
    Reports results of the Information Access Project, funded by King's College London and the British Library, Research and Development Department, set up to examine the effects of information technology, the electronic library and the Internet on the information seeking behaviour and research behaviour of academics in higher education. The project studied a team of theoretical physicists over 2 years using a qualitative, context situation, user centred methodology. Electronic resources, primarily electronic bulletin boards and electronic mail, were used to access information in 80% of the 48 research projects, ususally in conjunction with traditional methods. Discusses the changes in information activity, changed boundaries and speeding up of the work of the research community; increased visibility for researchers; formalization of the preprint process; replacement of formal with informal peer review; improved access to more current information; and the demise in the use of libraries. Drawbacks reported include: limitations of electronic mail communication; information overload; limitations of reliance on single information sources in terms of their focus; and the reduction in creative active information seeking. The main electronic information source for the high energy physicists, used in the study, was the High Energy Physics Theory (HEPTH) pre-print bulletin board: a service designed to provide rapid access to written research information available before it is published in periodical form

    Abstract
    This study focuses on the ways in which people define their source preferences in the context of seeking orienting information for nonwork purposes. The conceptual framework of the study combines ideas drawn from social phenomenology and information-seeking studies. The study utilizes Alfred Schutz's model describing the ways in which actors structure everyday knowledge into regions of decreasing relevance. It is assumed that this structuring based on the actor's interest at hand is also reflected in the ways in which an actor prefers information sources and channels. The concept of information source horizon is used to elicit articulations of source preferences. The empirical part of the study draws on interviews with 20 individuals active in environmental issues. Printed media (newspapers), the Internet, and broadcast media (radio, television) were preferred in seeking for orienting information. The major source preferences were content of information, and availability and accessibility. Usability of information sources, user characteristics such as media habits, and situational factors were mentioned less frequently as preference criteria.

    Abstract
    This paper is the second part of a two-part paper, which examines the transition to the electronic information era in academia. Seeks to establish from the published literature to what extent university researchers have accepted, and adapted to, the changes wrought in information activity by seemingly endless technological developments. Within the wider context of the impact of the changing information environment on each of the three clearly discernible components of academic research (the creation of knowledge and standards, the preservation of information, and the communication of knowledge and information to others), disciplinary-rooted differences in the conduct of research and their influence on information needs are identified, and the resulting inter- and intra-individual variations in researchers' information seeking behaviour are explored. Reviewing a large number of studies investigating the integration of electronic media into academic work, an attempt is made to paint the picture of academics' progressively harnessing the new technologies to scholarly information gathering endeavours, with the expressed hope of affording some insight into the directions and basic trends characterising the information activity of university faculty in an increasingly electronic environment.

    Abstract
    More complex contexts of information seeking require extensive thinking that involves an intellectual leap which carries the user `beyond the information given' (Bruner, 1973) to the construction of something `new'. According to Arnheim (1969) such thinking is directly affected by one's visual perception of the world and he argues that the most productive thinking results from this imagery. The application of visual or mental imagery to the relationships and structure in information seeking situations may be thought of as a constructive strategy for making meaning. This paper explores the use of mental imagery in the constructive process of information seeking. For the individual, the meaning of information is not inherent in the information itself but in his or her perception of it and how it fits into an image of the world or personal construct system (Boulding, 1961; Kelly, 1963). The use of imagery may facilitate a user's mental image of information and its relation to previously acquired knowledge and, thus, also facilitate new construction during the information seeking process. Mental imagery has been found to play an important role in creativity and problem solving. Shepard (1978) argues that some of the most creative thoughts and solutions which humans devise are those which are not confined to expression within linear verbal communication but rather spring from mental imagery that embraces a spatial approach to problem solving. Mental imagery is more concrete and visually constructive in nature than verbal methods of problem solving. This paper explores the role of imagery in the constructive tasks of problem solving and learning in the information seeking process.

    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.
