    Abstract
    Using the Arts & Humanities Citation Index (A&HCI) 2008, we apply mapping techniques previously developed for mapping journal structures in the Science and Social Sciences Citation Indices. Citation relations among the 110,718 records were aggregated at the level of 1,157 journals specific to the A&HCI, and the journal structures are questioned on whether a cognitive structure can be reconstructed and visualized. Both cosine-normalization (bottom up) and factor analysis (top down) suggest a division into approximately 12 subsets. The relations among these subsets are explored using various visualization techniques. However, we were not able to retrieve this structure using the Institute for Scientific Information Subject Categories, including the 25 categories that are specific to the A&HCI. We discuss options for validation such as against the categories of the Humanities Indicators of the American Academy of Arts and Sciences, the panel structure of the European Reference Index for the Humanities, and compare our results with the curriculum organization of the Humanities Section of the College of Letters and Sciences of the University of California at Los Angeles as an example of institutional organization.

    Abstract
    Despite the development of huge healthcare Web sites and powerful search engines, many searchers end their searches prematurely with incomplete information. Recent studies suggest that users often retrieve incomplete information because of the complex scatter of relevant facts about a topic across Web pages. However, little is understood about regularities underlying such information scatter. To probe regularities within the scatter of facts across Web pages, this article presents the results of two analyses: (a) a cluster analysis of Web pages that reveals the existence of three page clusters that vary in information density and (b) a content analysis that suggests the role each of the above-mentioned page clusters play in providing comprehensive information. These results provide implications for the design of Web sites, search tools, and training to help users find comprehensive information about a topic and for a hypothesis describing the underlying mechanisms causing the scatter. We conclude by briefly discussing how the analysis of information scatter, at the granularity of facts, complements existing theories of information-seeking behavior.

    Abstract
    Informationsdienste werden heutzutage von großen Teilen der Bevölkerung im Berufs- wie im Privatleben genutzt. Es ist ein wichtiges informationswissenschaftliches Thema, Informationsdienste adäquat zu beschreiben und ihre Qualität zu bewerten. Unser Information Service Evaluation (ISE) Modell führt unterschiedliche Traditionen der Evaluations- sowie der Technologieakzeptanzforschung zusammen und besteht aus fünf Dimensionen: Qualität des Informationsdienstes, Nutzer, Informationsakzeptanz, Informationsumfeld und Zeit. Der Überblicks­artikel erläutert diese Dimension und bietet einen Einblick in ein flexibel handhabbares und umfassendes holistisches Modell der Beschreibung und Bewertung von Informationsdiensten.

    Abstract
    This study analyzes the search behavior of Dutch-speaking nursing students with a nonnative knowledge of English who searched for information in MEDLINE/PubMed about a specific theme in nursing. We examine whether and to what extent their search efficiency is affected by their language skills. Our task-oriented approach focuses on three stages of the information retrieval process: need articulation, query formulation, and relevance judgment. The test participants completed a pretest questionnaire, which gave us information about their overall experience with the search system and their self-reported computer and language skills. The students were briefly introduced to the use of PubMed and MeSH (medical subject headings) before they conducted their keyword-driven subject search. We assessed the search results in terms of recall and precision, and also analyzed the search process. After the search task, a satisfaction survey and a language test were completed. We conclude that language skills have an impact on the search results. We hypothesize that language support might improve the efficiency of searches conducted by Dutch-speaking users of PubMed.

    Abstract
    Hundreds of scholarly studies have investigated various aspects of Wikipedia. Although a number of literature reviews have provided overviews of this vast body of research, none has specifically focused on the readers of Wikipedia and issues concerning its readership. In this systematic literature review, we review 99 studies to synthesize current knowledge regarding the readership of Wikipedia and provide an analysis of research methods employed. The scholarly research has found that Wikipedia is popular not only for lighter topics such as entertainment but also for more serious topics such as health and legal information. Scholars, librarians, and students are common users, and Wikipedia provides a unique opportunity for educating students in digital literacy. We conclude with a summary of key findings, implications for researchers, and implications for the Wikipedia community.

    Abstract
    Controversy is a complex concept that has been attracting attention of scholars from diverse fields. In the era of Internet and social media, detecting controversy and controversial concepts by the means of automatic methods is especially important. Web searchers could be alerted when the contents they consume are controversial or when they attempt to acquire information on disputed topics. Presenting users with the indications and explanations of the controversy should offer them chance to see the "wider picture" rather than letting them obtain one-sided views. In this work we first introduce a formal model of controversy as the basis of computational approaches to detecting controversial concepts. Then we propose a classification based method for automatic detection of controversial articles and categories in Wikipedia. Next, we demonstrate how to use the obtained results for the estimation of the controversy level of search queries. The proposed method can be incorporated into search engines as a component responsible for detection of queries related to controversial topics. The method is independent of the search engine's retrieval and search results recommendation algorithms, and is therefore unaffected by a possible filter bubble. Our approach can be also applied in Wikipedia or other knowledge bases for supporting the detection of controversy and content maintenance. Finally, we believe that our results could be useful for social science researchers for understanding the complex nature of controversy and in fostering their studies.

    Abstract
    A naïve user seeking introductory information on a topic may perceive a domain as it is shown by the search results in a database; however, inconsistencies in indexing can misrepresent the full picture of the domain by including irrelevant documents or omitting relevant ones, sometimes inexplicably. A bibliometric analysis was conducted on the domain of ethics in knowledge organization in the World of Science (WoS) and Library, Information Science & Technology Abstracts (LISTA) databases to discern how it is being presented by search results in those databases and to attempt to determine why inconsistencies occurred.

    Abstract
    Patient portals have the potential to provide content that is specifically tailored to a patient's information needs based on diagnoses and other factors. In this work, we conducted a survey of 41 lung cancer patients at an outpatient lung cancer clinic at the medical center of the University of California, Los Angeles, to gain insight into these perceived information needs and opinions on the design of a portal to fulfill them. We found that patients requested access to information related to diagnosis and imaging, with more than half of the patients reporting that they did not anticipate an increase in anxiety due to access to medical record information via a portal. We also found that patient educational background did not lead to a significant difference in desires for explanations of reports and definitions of terms.

    Abstract
    Many information portals are adding social features with hopes of enhancing the overall user experience. Invitations to join and welcome pages that highlight these social features are expected to encourage use and participation. While this approach is widespread and seems plausible, the effect of providing and highlighting social features remains to be tested. We studied the effects of emphasizing social features on users' response to invitations, their decisions to join, their willingness to provide profile information, and their engagement with the portal's social features. The results of a quasi-experiment found no significant effect of social emphasis in invitations on receivers' responsiveness. However, users receiving invitations highlighting social benefits were less likely to join the portal and provide profile information. Social emphasis in the initial welcome page for the site also was found to have a significant effect on whether individuals joined the portal, how much profile information they provided and shared, and how much they engaged with social features on the site. Unexpectedly, users who were welcomed in a social manner were less likely to join and provided less profile information; they also were less likely to engage with social features of the portal. This suggests that even in online contexts where social activity is an increasingly common feature, highlighting the presence of social features may not always be the optimal presentation strategy.

    Abstract
    The rapid rise of Wikipedia as an information source has placed the traditional role of librarians as information gatekeepers and guardians under scrutiny with much of the professional literature suggesting that librarians are polarized over the issue of whether Wikipedia is a useful reference tool. This qualitative study examines the perceptions and behaviours of National Library Board (NLB) of Singapore librarians with regards to information seeking and usage of Wikipedia. It finds that instead of polarized attitudes, most librarians, although cautious about using Wikipedia in their professional capacity, hold a range of generally positive attitudes towards the online encyclopaedia, believing that it has a valid role to play in the information seeking of patrons today. This is heartening because it suggests the existence within the librarian population of attitudes that can be tapped to engage constructively with Wikipedia. Three of these in particular are briefly discussed at the end of the article: Wikipedia's ability to appeal to the socalled "digital natives," its role as a source of non-Western information, and its potential to enable a revitalization of the role of librarians as public intellectuals contributing to a democratic information commons.

    Abstract
    Im Studiengang "Information Science & Engineering" der Hochschule Darmstadt untersuchten vier Studenten des vierten Semesters in der Lehrveranstaltung "Qualitätsbewertung von Informationsressourcen", betreut von Prof. Dr. Heide Gloystein, die Qualität von Online-Informationsressourcen anhand von standardisierten Suchanfragen zu einem festgelegten Thema. Die Suchergebnisse werden nach einem vorher definierten Bewertungskatalog untersucht. Die beispielhaft ausgewählten Informationsressourcen teilen sich in folgende Kategorien ein: Internet/Web 1.0, Datenbanken, Web 2.0, sowie Bibliografische Datenbanken/OPAC. Die Fachdatenbanken schneiden hierbei erwartungsgemäß am Besten ab. Weniger professionelle Informationsquellen, wie Web 2.0-Anwendungen sind ungeeignet als fachliche Informationsressource. Das Endergebnis wird zusammengefasst in einer Matrix präsentiert, die die Stärken und Schwächen der einzelnen Ressourcen durch einheitliche Bewertungskriterien vergleichbar machen.

    Abstract
    Wikipedia is increasingly an important source of information for many. Hence, it is important to develop an understanding of how it is situated within society and the wider roles it is called onto perform. This article argues that one of these roles is as a depository of collective memory. Building on the work of Pentzold, I present a case study of the English Wikipedia article on the Vietnam War to demonstrate that the article, or more accurately, its talk pages, provide a forum for the contestation of collective memory. I further argue that this function is one that should be supported by libraries as they position themselves within a rapidly changing digital world.

    Abstract
    Die Wikipedia ist sowohl hinsichtlich ihres Umfangs als auch hinsichtlich ihrer Nutzung die heute bedeutendste Enzyklopädie. Auch innerhalb der Wissenschaft spielt sie, vor allem als leicht zugänglicher Rechercheeinstieg, eine wichtige Rolle. In diesem Zusammenhang steht die Glaubwürdigkeit der Wikipedia immer wieder im Fokus, da ihre Inhalte nicht durch Fachexperten kontrolliert, sondern von jedermann ediert werden können. Jedoch ist innerhalb der Wikipediacommunity ein starkes Bemühen um Glaubwürdigkeit festzustellen. Anhand der Analyse ausgewählter Redaktionsprinzipien der Wikipedia und der Auswertung einer Fallstudie zur Erzeugung von Glaubwürdigkeit in der deutschsprachigen Wikipedia lassen sich Implikationen für Information Professionals ableiten. Besonders Bibliothekarinnen und Bibliothekare können durch ihren Zugang zu Literatur einerseits und mit ihren Recherchekenntnissen andererseits dabei helfen, die Glaubwürdigkeit der Wikipedia zu steigern.

    Abstract
    With the rise of Wikipedia as a first-stop source for scientific information, it is important to understand whether Wikipedia draws upon the research that scientists value most. Here we identify the 250 most heavily used journals in each of 26 research fields (4,721 journals, 19.4M articles) indexed by the Scopus database, and test whether topic, academic status, and accessibility make articles from these journals more or less likely to be referenced on Wikipedia. We find that a journal's academic status (impact factor) and accessibility (open access policy) both strongly increase the probability of it being referenced on Wikipedia. Controlling for field and impact factor, the odds that an open access journal is referenced on the English Wikipedia are 47% higher compared to paywall journals. These findings provide evidence is that a major consequence of open access policies is to significantly amplify the diffusion of science, through an intermediary like Wikipedia, to a broad audience.
