    Abstract
    Most information systems share a common assumption: information seeking is discrete. Such an assumption neither reflects real-life information seeking processes nor conforms to the perspective of phenomenology, "life is a journey constituted by continuous acquisition of knowledge." Thus, this study develops and validates a theoretical model that explains successive search experience for essentially the same information problem. The proposed model is called Multiple Information Seeking Episodes (MISE), which consists of four dimensions: problematic situation, information problem, information seeking process, episodes. Eight modes of multiple information seeking episodes are identified and specified with properties of the four dimensions of MISE. The results partially validate MISE by finding that the original MISE model is highly accurate, but less sufficient in characterizing successive searches; all factors in the MISE model are empirically confirmed, but new factors are identified as weIl. The revised MISE model is shifted from the user-centered to the interaction-centered perspective, taking into account factors of searcher, system, search activity, search context, information attainment, and information use activities.

    Abstract
    In this paper results of a field study into the need for research information of different user groups are presented: scientists, policy makers and policy researchers, industry and media. Main questions of semi-structured interviews were: what kind of research information users need, what kind of research information resources are used and which information resources are missing at the moment. User groups are missing for a diversity of reasons the overview of research, experts and institutes in the different scientific fields. Especially for the accessibility and transparency of the scientific world these overviews are reported to be needed. Neither Google nor any of the research institutes or policy research organisations are able to present surveys for different science fields at the moment. Giving users the possibility to search, browse and navigate through accessible and more specialised layers of research information might give answers to different user groups simultaneously.

    Abstract
    This article marries the study of serious leisure pursuits with library and information science's (LIS) interest in people's everyday use, need, seeking, and sharing of information. Using a qualitative approach, the role of information as a phenomenon was examined in relation to the leisure activity of hobbyist collecting. In the process, a model and a typology for these collectors were developed. We find that the information needs and information seeking of hobbyist collectors is best represented as an interrelationship between information and object needs, information sources, and interactions between collectors and their publics. Our model of the role of information in a particular domain of hobbyist collecting moves away from the idea of one individual seeking information from formal systems and shifts towards a model that takes seriously the social milieu of a community. This collecting community represents a layer of a social system with complex interactions and specialized information needs that vary across collector types. Only the serious collectors habitually engage in information seeking and, occasionally, in information dissemination, in the traditional sense, yet information flows through the community and serves as a critical resource for sustaining individual and communal collecting activities.

    Abstract
    The role of a modern librarian has become more and more demanding in the information age. One of the new challenges for the information specialists is what's usually called "the teaching librarian", meaning that the librarian or information specialist should be able to teach at least basic practical searching skills to the patrons in need for relevant information. Query Performance Analyser (QPA) is a tool for analysing and comparing the performance of individual queries. It has been developed in the department of information studies at the University of Tampere. It can be used in user training to demonstrate the characteristics of IR systems and different searching strategies. Usually users can't get any feedback about the effectiveness of their queries and therefore may have difficulties to perceive the actual fectiveness of a query formulated, or the effect changes between queries. QPA provides a instant visual feedback about the performance of a given query and gives the user a possibility to compare the effectiveness of multiple queries and the performance of different query formulation strategies. QPA is based on predefined search topics. They all contain a corpus of documents that are relevant to the given topic. The purpose of this paper is to give a brief insight to the infrastructure of QPA, the basic :Functionality of the QPA-based game, and to its implementation in IR education.

    Abstract
    The purpose of this entry is to present and analyze the relationship between learning and information seeking. The analysis draws on research studies on information seeking set in educational contexts and is framed in theories of learning, mainly constructivism. Themes of the entry are based on five dimensions of the relationship between learning and information seeking: 1) seeking information for learning purposes; 2) learning information seeking; 3) teaching information seeking; 4) learning from information; and 5) reshaping conditions for information seeking and learning through information and communications technologies (ICTs). Conclusions are that the fields of learning and information seeking draw nearer to one another partly due to educational ideas based in constructivism and partly due to the development of digital tools that reshape conditions for learning in postmodern society. This development contributes to the transformation of the professional role of librarians, implying an emphasis on the pedagogical aspects of the profession. Future prospects for information seeking research and practice linked to learning may involve strengthened interests in the cognitive authority and expertise of information as well as information sharing through communicative interaction.

    Abstract
    Collaborative information behavior is an essential aspect of organizational work; however, we have very limited understanding of this behavior. Most models of information behavior focus on the individual seeker of information. In this paper, we report the results from two empirical studies that investigate aspects of collaborative information behavior in organizational settings. From these studies, we found that collaborative information behavior differs from individual information behavior with respect to how individuals interact with each other, the complexity of the information need, and the role of information technology. There are specific triggers for transitioning from individual to collaborative information behavior, including lack of domain expertise. The information retrieval technologies used affect collaborative information behavior by acting as important supporting mechanisms. From these results and prior work, we develop a model of collaborative information behavior along the axes of participant behavior, situational elements, and contextual triggers. We also present characteristics of collaborative information system including search, chat, and sharing. We discuss implications for the design of collaborative information retrieval systems and directions for future work.

    Abstract
    Information seeking is a fluid and situation dependent activity where a seeker's actions are influenced by access to information, perceived quality (or information fit) and trust in the information source. All of these factors combined create an ever-changing information-seeking environment. Generally, traditional models and survey methodologies capture a "snapshot in time" of a particular information-seeking activity, but fail to capture the multivalent influences of things such as chance, frequency of encounters, strength of source or the introduction of new or multiple influencers. Using the tool of fuzzy control systems, a new conceptual model is introduced that not only diagrams the influences on the information seeker, but also provides a framework to devise (or refine existing) communications strategies.

    Abstract
    Key terms related to information searching and search models are defined. A historic context is provided to illustrate the evolution of the four main digital environments that users interact with in their search process to offer readers background information regarding the transition from manual information systems to computer-based information retrieval (IR) systems, as well as the transition from intermediary searching to end-user searching. Emphasis is placed on the review of different levels of information searching from search tactics/moves, search strategies, and usage patterns, to search models and associated factors in relation to task, user knowledge structure, IR system design, and social-organization context. Search models are further classified into two types, with one type illustrating information search process (ISP) and the other type emphasizing the factors that influence the process. In addition, unsolved problems and future research are discussed and suggested.

    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
    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
    In this issue we begin with Lamb, King and Kling who are interested in the effect of the industry environment on information gathering practices, particularly those involving information and communication technologies like online searching. They studied use of online services in 26 widely differing California firms operating in law, real estate, or biotechnology over a 17 month period. Data was gathered through semi-structured on-site interviews. Five influences on online usage were identified: interaction with regulatory agencies; demonstration of competence to clients; client expectations for timely, cost effective information; the possibility of shifting information responsibilities outside the organization; and the existence of industry wide infrastructures as information sources. The institutional and technical environment of a firm consistently circumscribes the domain in which choices of online resources are made by its employees. Firms the operate in highly technical and institutional environments have more incentive to gather information than do those in low tech unregulated industries.

    Abstract
    Pettigrew, Durrance, and Unruh report on data collected by survey, interview, field observation and focus groups concerning three communities recognized for community information networks in which the local public library played a leading role. The survey was posted for 73 days on the website of each network and yielded 197 responses providing insights on how the public uses CI systems, barriers encountered, and resulting benefits to users and communities. Responding users were diverse demographically, and sought a wide variety of information types. The information types were broader than previous CI studies with a strong emphasis on employment, volunteerism, social services, local history and genealogy, sale, exchange and donation of goods, news, and technical information. Barriers identified were technological, economic, geographic, search skill related, cognitive, and psychological, as well as a large class of information related barriers concerning the quality of the information provided, its accessibility, and security. Users are identified who browse the CI system with particular interest in discovering material of potential value to others. The systems are valued and used by the adult population and seem to strengthen existing communities while stimulating the formation of information communities.

    Abstract
    Auslöser für die Entstehung neuer Initiativen zur Reformierung des Systems wissenschaftlicher Kommunikation sind die Konflikte zwischen den beteiligten Akteuren in der Publikationskette, die sich im Übergang zum elektronischen Medium verschärfen. Von Vertretern des open access wird die zunehmende Beeinträchtigung des Zugangs zu Wissen und Information kritisiert. Peter Suber, Herausgeber des SPARC OPEN ACCESS-Newsletter, unterscheidet zwischen Preisbarrieren ("price barriers") und Zugänglichkeitsbarrieren ("permission barriers"), die den freien Umgang mit Wissen und Information zunehmend einschränken.

    Abstract
    Domain novice users in the beginning stages of researching a topic find themselves searching for information via information retrieval (IR) systems before they have identified their information need. Pre-Internet access technologies adapted by current IR systems poorly serve these domain novice users, whose behavior might be characterized as rudderless and without a compass. In this article we describe a conceptual design for an information retrieval system that incorporates standard information need identification classification and subject cataloging schemes, called the INIIReye System, and a study that tests the efficacy of the innovative part of the INIIReye System, called the Associative Index. The Associative Index helps the user put together his or her associative thoughts-Vannevar Bush's idea of associative indexing for his Memex machine that he never actually described. For the first time, data from the study reported here quantitatively supports the theoretical notion that the information seeker's information need is identified through transformation of his/her knowledge structure (i.e., the seeker's cognitive map or perspective an the task far which information is being sought).

    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
    Recent years have seen an explosion of interest in human information behavior in part attributable to the rapid development of the Internet and associated information technologies. Concomitantly there has been substantial growth in theoretic frames, research, and substantive models. However, these approaches have often been fragmentary, dependent on the goals of disparate disciplines that are interested in differing aspects of information behavior. They often have been rooted in the most rational of contexts, libraries, where individuals come with a defined problem, or information technology systems, that have their own inherent logic. Attempts to extend this work to everyday life contexts often run into disquieting findings related to the benefits of ignorance and the seeming irrationality of human information behavior. A broader view of our social world leads us to richer policy implications for our work. We live in exciting times, in an increasingly flattened world, where the ability for people to assimilate information they find into coherent personal strategies is perhaps the critical modern survival skill.

    Abstract
    Purpose - This study provides evidence on the actual information-seeking behaviour of students in a digital scholarly environment, not what they thought they did. It also compares student information-seeking behaviour with that of other academic communities, and, in some cases, for practitioners. Design/methodology/approach - Data were gathered as part of CIBER's ongoing Virtual Scholar programme. In particular log data from two digital journals libraries, Blackwell Synergy and OhioLINK, and one e-book collection (Oxford Scholarship Online) are utilized. Findings - The study showed a distinctive form of information-seeking behaviour associated with students and differences between them and other members of the academic community. For example, students constituted the biggest users in terms of sessions and pages viewed, and they were more likely to undertake longer online sessions. Undergraduates and postgraduates were the most likely users of library links to access scholarly databases, suggesting an important "hot link" role for libraries. Originality/value - Few studies have focused on the actual (rather than perceived) information-seeking behaviour of students. The study fills that gap.
