    Abstract
    Das Web 2.0 hat einen Paradigmenwechsel im Umgang mit Informationen und damit eng verbunden im Wissenserwerb eingeleitet. Theoretisch gesehen hat jeder offenen Zugang zu vielfältigen Informationen und kann gleichzeitig selbst Inhalte beisteuern - z.B. in Sozialen Netzwerken, in Weblogs oder Wikis - und Websites oder andere Dokumente (Videos, Slideshows o.ä.) veröffentlichen und mit anderen Nutzern teilen. Dieser Demokratisierungsprozess von Wissensproduktion, -kommunikation und -erwerb ist allerdings nicht frei von Kontroversen. Das verstärkte Nebeneinander von sachlich richtiger und relevanter Information einerseits und Belanglosigkeiten andererseits ruft auch Gegner auf den Plan. Sie sprechen von einem Information Overkill und befürchten den Niedergang der klassischen Bildung. Führen freie Wissenszugänge im Netz tatsächlich zu weniger Bildung? Was macht eine Website zu einer zuverlässigen und vertrauenswürdigen Quelle? Wie können aus der Fülle von Webressourcen die qualitativ hochwertigen herausgefiltert werden? Welchen Beitrag kann dabei Social Software leisten? Welches sind die Konstituenten einer Informationskompetenz 2.0, über die User verfügen sollten, um mit vorgefundenen Ressourcen adäquat umgehen zu können? Und inwiefern sind Bibliotheken - die sich ja zunehmend als Teaching Libraries verstehen - hier gefordert? Auf diese Fragen versucht das vorliegende Buch Antworten zu geben. Der Fokus liegt auf dem Umgang mit Wissensressourcen im Web 2.0, wobei ebenso theoretische wie praktische Implikationen berücksichtigt und ausgewählte Evaluierungsansätze hinsichtlich ihrer praktischen Anwendbarkeit für die User diskutiert werden.

    Abstract
    In this paper we present results from an investigation of religious information searching based on analyzing log files from a large general-purpose search engine. From approximately 15 million queries, we identified 124,422 that were part of 60,759 user sessions. We present a method for categorizing queries based on related terms and show differences in search patterns between religious searches and web searching more generally. We also investigate the search patterns found in queries related to 5 religions: Christianity, Hinduism, Islam, Buddhism, and Judaism. Different search patterns are found to emerge. Results from this study complement existing studies of religious information searching and provide a level of detailed analysis not reported to date. We show, for example, that sessions involving religion-related queries tend to last longer, that the lengths of religion-related queries are greater, and that the number of unique URLs clicked is higher when compared to all queries. The results of the study can serve to provide information on what this large population of users is actually searching for.

    Abstract
    Purpose - The purpose of this paper is to examine the role of information literacy (IL) and digital literacy under the circumstances and challenges of the Web 2.0 environment. Design/methodology/approach - Desk research was done in order acquire a picture about the nature of the Web 2.0 and Library 2.0 in regard to their influence on literacy requirements. The hypothesis that differential literacies have to be offered to diverging groups of users, similarly to traditional library services that cater for different user needs depending on the type of the given library was tested. Findings - Professional goals characterize first of all different groups of professionals, teaching staff and researchers, as well as students. Thus, their need in information is different from that of other categories of users. Consequently, they require literacies similar to services traditionally offered by academic and special libraries. Amateur content is more compatible with the mission of public libraries and it is more suitable for Web 2.0 and Library 2.0 applications. Research limitations/implications - New principles of IL are outlined in this paper which will help practitioners in designing goal-oriented IL education. Practical implications - The practical implications need to be studied in the course of further research. Originality/value - The findings represent a small but valuable asset to the discussion about new approaches towards IL education.

    Abstract
    In Zeiten zunehmend wissensintensiver Berufsbilder besteht eine große Herausforderung heutiger Unternehmen darin, die zur Unterstützung organisatorischen Handelns erforderliche Information effizient und effektiv zur Verfügung zu stellen. Eine Grundlage für die Entwicklung einer adäquaten Informationsumgebung legt dabei das umfassende Verständnis des Kontexts und Verhaltens von Mitarbeitern im Umgang mit Information. Beides unterliegt jedoch einem steten Wandel und stellt hohe Anforderungen an die Flexibilität von Arbeitsplatzkonzepten und der Gestaltung von Informationsumgebungen. In diesem Artikel wird daher die aktuelle Bedeutung und Entwicklung informationswissenschaftlicher Ansätze zur Modellierung von Informationssuchverhalten, deren Methoden, sowie zentrale Konzepte und Erkenntnisse vorgestellt. Anschließend wird die Bedeutung dieser Modelle für den Arbeitsplatz-Kontext in Zeiten zunehmend wissensintensiver Tätigkeiten untersucht. Anhand der Wandlung des primär informativ genutzten Internet zu einem partizipativen Social Web wird daraufhin erörtert, welche neuen Entwicklungen es in der Erforschung des Nutzerkontexts zu berücksichtigen gilt. Die beispielhafte Betrachtung aktueller Forschungsergebnisse auf diesem Gebiet mündet in einer Diskussion weiteren Forschungsbedarfs.

    Abstract
    Keeping up to date with research developments is a central activity of academic researchers, but researchers face difficulties in managing the rapid growth of available scientific information. This study examined how researchers stay up to date, using the information journey model as a framework for analysis and investigating which dimensions influence information behaviors. We designed a 2-round study involving semistructured interviews and prototype testing with 61 researchers with 3 levels of seniority (PhD student to professor). Data were analyzed following a semistructured qualitative approach. Five key dimensions that influence information behaviors were identified: level of seniority, information sources, state of the project, level of familiarity, and how well defined the relevant community is. These dimensions are interrelated and their values determine the flow of the information journey. Across all levels of professional expertise, researchers used similar hard (formal) sources to access content, while soft (interpersonal) sources were used to filter information. An important "pain point" that future information tools should address is helping researchers filter information at the point of need.

    Abstract
    Information und Wissen werden seit dem späten 20. Jahrhundert als Produkt bzw. Dienstleistung erkannt, für deren Vermittlung ein Managementprozess notwendig ist. In der heutigen schnelllebigen Zeit nimmt die Bedeutung der Ressource Wissen kontinuierlich zu, weil Wandlungsprozesse sowie Änderungen des Marktes einen akuten Handlungsbedarf bedingen. Effiziente Vernetzung und Neukombination von Information und Wissen sind Voraussetzung für erfolgreiche Umgestaltung. Diese Prozesse finden sowohl im privatwirtschaftlichen Umfeld als auch im öffentlichen Sektor statt. Insbesondere Bibliotheken sehen sich durch den verstärkten Gebrauch des Internets mit der Herausforderung konfrontiert, ihr traditionelles Berufsbild als Informations- und Wissensvermittler an die neuen Technologien, vor allem die des Web 2.0 und des Semantic Web, anzupassen. Dies erfordert eine Weiterentwicklung der innerbetrieblichen Prozesse und die Berücksichtigung neuer technischer Entwicklungen. Die Bereitstellung neuer technischer Systeme allein ist nicht ausreichend, sondern die Systeme müssen durch die Mitarbeitenden kompetent genutzt werden können. So formuliert es Wawra: "Alle sind sich - jedenfalls scheint es so - darin einig, dass die Leistungen des modernen wissenschaftlichen und öffentlichen Bibliothekswesens kaum mehr in der geforderten Qualität zu erbringen sind, wenn die Träger dieser Prozesse - die Mitarbeiterinnen und Mitarbeiter - nicht über die dafür notwendigen Qualifikationen verfügen:"

    Abstract
    Eine Recherche im Web kann für die journalistische Recherche zielführend sein. Es müssen jedoch einige Dinge beachtet werden. So eignet sich etwa die Wikipedia mehr als Rechercheeinstieg denn als Allheilmittel. Auch sollten über die Universalsuchmaschinen hinaus die erweiterte Suche und Spezialsuchmaschinen genutzt werden. Es empfiehlt sich das Anlegen eines Rechercheprotokolls zur Unterstützung einer systematischen Recherche. Auch das Verifizieren von Quellen ist notwendig. Dieser Text bietet nach einigen - negativen wie positiven - Beispielen zu den genannten Punkten Empfehlungen für den journalistischen Umgang mit Suchmaschinen, anderen Suchwerkzeugen sowie Hinweise für strukturierte Internet-Recherchen.

    Abstract
    Large amounts of health-related information of different types are available on the web. In addition to authoritative health information sites maintained by government health departments and healthcare institutions, there are many social media sites carrying user-contributed information. This study sought to identify the types of drug information available on consumer-contributed drug review sites when compared with authoritative drug information websites. Content analysis was performed on the information available for nine drugs on three authoritative sites (RxList, eMC, and PDRhealth) as well as three drug review sites (WebMD, RateADrug, and PatientsLikeMe). The types of information found on authoritative sites but rarely on drug review sites include pharmacology, special population considerations, contraindications, and drug interactions. Types of information found only on drug review sites include drug efficacy, drug resistance experienced by long-term users, cost of drug in relation to insurance coverage, availability of generic forms, comparison with other similar drugs and with other versions of the drug, difficulty in using the drug, and advice on coping with side effects. Drug efficacy ratings by users were found to be different across the three sites. Side effects were vividly described in context, with user assessment of severity based on discomfort and effect on their lives.

    Abstract
    The user-centered approach to information retrieval emphasizes the importance of a user model in determining what information will be most useful to a particular user, given their context. Mediated search provides an opportunity to elaborate on this idea, as an intermediary's elicitations reveal what aspects of the user model they think are worth inquiring about. However, empirical evidence is divided over whether intermediaries actually work to develop a broadly conceived user model. Our research revisits the issue in a web research services setting, whose characteristics are expected to result in more thorough user modeling on the part of intermediaries. Our empirical study confirms that intermediaries engage in rich user modeling. While intermediaries behave differently across settings, our interpretation is that the underlying user model characteristics that intermediaries inquire about in our setting are applicable to other settings as well.

    Abstract
    Purpose - The purpose of this paper is to elaborate how source preference criteria are defined in the context of everyday projects that require the seeking of problem-specific information. More specifically, to find out how information seekers explain their preference criteria by characterizing the perceived strengths and weaknesses of diverse sources. Design/methodology/approach - The approach takes the form of qualitative content analysis of empirical data gathered by semi-structured interviews with 16 prospective home buyers in 2008. The source preference criteria were elicited by making use of the construct of information source horizon. Findings - Networked sources were favoured most strongly, followed by printed media, human sources and organizational sources. Content of information was the primary source preference criterion. Availability of information was a fairly important criterion, while user characteristics, usability of information and situational factors were fairly marginal in this regard. In the definition of the preference criteria, more emphasis was placed on the perceived strengths than weaknesses of sources. Positive qualities such as "provides updated information" were referred to particularly while judging the relevance of the networked sources. Negative qualities like "outdated information" were primarily associated with printed media and organizational sources. Research limitations/implications - The study is exploratory, drawing on a relatively small sample recruited through a web-based service. Thus, the findings cannot be generalized to prospective home buyers. Practical implications - Prospective home buyers tend to favour web-based information sources and services. They should provide the customers with detailed information about the property, including photos. Originality/value - The paper specifies the picture of user-defined relevance judgment in the context of everyday life information seeking.

    Abstract
    The advent and development of the Internet has changed students' pattern of information seeking behaviors. That is also the case in Iran. The current research was carried out by interviewing with and observing of 20 intermediate girl students to assess their information seeking behavior on the web environment through a qualitative approach. Findings indicate an acceptable level of access to the Internet and vast use of web search engines by the girl students in Tehran. However, students' knowledge of the concept and how search engines work and also about the methods and tools of retrieving information from electronic sources other than the search engines is poor. The study also shows that, compared to the Internet, the role of libraries and librarians are gradually diminishing in fulfilling the students' information needs. Authors recommend that school librarians can provide different instructional and information literacy programs to help students improve their information seeking behavior and their knowledge of the Internet.

    Abstract
    The quality of online health information for consumers has been a critical issue that concerns all stakeholders in healthcare. To gain an understanding of how quality is evaluated, this systematic review examined 165 articles in which researchers evaluated the quality of consumer-oriented health information on the web against predefined criteria. It was found that studies typically evaluated quality in relation to the substance and formality of content, as well as to the design of technological platforms. Attention to design, particularly interactivity, privacy, and social and cultural appropriateness is on the rise, which suggests the permeation of a user-centered perspective into the evaluation of health information systems, and a growing recognition of the need to study these systems from a social-technical perspective. Researchers used many preexisting instruments to facilitate evaluation of the formality of content; however, only a few were used in multiple studies, and their validity was questioned. The quality of content (i.e., accuracy and completeness) was always evaluated using proprietary instruments constructed based on medical guidelines or textbooks. The evaluation results revealed that the quality of health information varied across medical domains and across websites, and that the overall quality remained problematic. Future research is needed to examine the quality of user-generated content and to explore opportunities offered by emerging new media that can facilitate the consumer evaluation of health information.

    Abstract
    The aim of this study was to measure the efficiency of the system by which scientists worldwide communicate results to each other, providing one measure of the degree to which the system, including all media, functions well. A randomly selected and representative sample of 246 active research scientists worldwide was surveyed. The main measure was the reported rate of "late finds": scientific literature that would have been useful to scientists' projects if it had been found at the beginning of these projects. The main result was that 46% of the sample reported late finds (±6.25%, p0.05). Among respondents from European Union countries or other countries classified as "high income" by the World Bank, 42% reported late finds. Among respondents from low- and middle-income countries, 56% reported late finds. The 42% rate in high-income countries in 2009 can be compared with results of earlier surveys by Martyn (1964a, b, 1987). These earlier surveys found a rate of 22% late finds in 1963-1964 and a rate of 27% in 1985-1986. Respondents were also queried about search habits, but this study failed to support any explanations for this increase in the rate of late finds. This study also permits a crude estimate of the cost in time and money of the increase in late finds.

    Abstract
    As new technologies and information delivery systems emerge, the way in which individuals search for information to support research, teaching, and creative activities is changing. To understand different aspects of researchers' information-seeking behavior, this article surveyed 2,063 academic researchers in natural science, engineering, and medical science from five research universities in the United States. A Web-based, in-depth questionnaire was designed to quantify researchers' information searching, information use, and information storage behaviors. Descriptive statistics are reported. Additionally, analysis of results is broken out by institutions to compare differences among universities. Significant findings are reported, with the biggest changes because of increased utilization of electronic methods for searching, sharing, and storing scholarly content, as well as for utilizing library services. Generally speaking, researchers in the five universities had similar information-seeking behavior, with small differences because of varying academic unit structures and myriad library services provided at the individual institutions.

    Abstract
    Purpose - The current study aims to review the different publications dealing with information literacy and the emerging trends reflected over the ten years, 1999-2009, in the Web of Science (WOS) database. Design/methodology/approach - The study presents both a statistical descriptive analysis of document type, subject areas, authors, source titles, publication years, languages, countries and keywords of publications extracted from the WOS database, as well as a thorough content analysis of keywords and abstracts extracted from the WOS database. Findings - The main results suggest that the term information literacy has various characteristics in an additional and interesting context: health and medicine. This finding may reflect a tendency of association between information literacy and health and medicine and stresses people's need for information literacy in this specific context. Originality/value - The current study emphasises the notion that information literacy is no longer an issue for librarians or educators only.

    Abstract
    This study presents and tests a research model of the outcomes of information literacy instruction (ILI) given to undergraduate business students. This model is based on expectation disconfirmation theory and insights garnered from a recent qualitative investigation of student learning outcomes from ILI given at three business schools. The model was tested through a web survey administered to 372 students. The model represents psychological, behavioral, and benefit outcomes as second-order molecular constructs. Results from a partial least squares (PLS) analysis reveal that expectation disconfirmation influences perceived quality and student satisfaction. These in turn affect student psychological outcomes. Further, psychological outcomes influence student behaviors, which in turn affect benefit outcomes. Based on the study's findings, several recommendations are made.

    Abstract
    The overall goal of this study is to explain how information literacy instruction (ILI) influences the adoption of online library resources (OLR) by business students. A theoretical model was developed that integrates research on ILI outcomes and technology adoption. To test this model, a web-based survey, which included both closed and open-ended questions, was administered to 337 business students. Findings indicate that the ILI received by students is beneficial in the initial or early stages of OLR use; however, students quickly reach a saturation point where more instruction contributes little, if anything, to the final outcome, such as reduced OLR anxiety and increased OLR self-efficacy. Rather, it is the independent, continuous use of OLR after receiving initial, formal ILI that creates continued positive effects. Importantly, OLR self-efficacy and anxiety were found to be important antecedents to OLR adoption. OLR anxiety also partially mediates the relationship between self-efficacy and perceived ease of use. Implications for theory and practice are discussed.

    Abstract
    Drawing on the ideas of process philosophy, this study elaborates the nature of information-seeking process by approaching them as temporal developments. To this end, a conceptual analysis was made by comparing key models which approach information seeking as stage-based and cyclic processes. The nature of such processes was scrutinized by devoting attention to two main aspects, that is, the temporal order in which the constituents of information seeking appear during the process, and the changes occurring in the constituents. Stage-based approaches draw on linear time concept by conceptualizing such processes as sets of consecutive activities progressing toward a final point. Cyclic approaches conceptualize information-seeking processes as sets of iterative activities which may be repeated. The findings suggest that stage-based and cyclic approaches should not be opposite approaches; rather, they complement each other. However, cyclic models emphasizing the importance of feedback loops have gained more popularity in the modeling of web searching, whereas the interest in the development of stage-based approaches has decreased since the 1990s.
