    Abstract
    Wikimedia Deutschland hat rund 150 hauptamtliche Mitarbeitende. Von den Erlösen aber kauft sich niemand eine Yacht. Ein Gastbeitrag. Online-Plattformen dominieren in vielen Bereichen unser Leben. Wie wir einkaufen, wie wir miteinander kommunizieren, wie wir Informationen sammeln - all das wird von einigen wenigen kommerziellen Plattformen mitbestimmt. Längst drängt sich der Eindruck auf, das Netz sei durchkommerzialisiert. Dabei gibt es sie noch: einige wenige Projekte im Netz, die nicht auf Profit ausgerichtet sind, sondern dem Gemeinwohl zugutekommen.

    Abstract
    The growing number of networked information resources and services offers unprecedented opportunities for delivering high quality information to the computer desktop of a wide range of individuals. However, currently there is a reliance on a database retrieval model, in which endusers use keywords to search large collections of automatically indexed resources in order to find needed information. As an alternative to the database retrieval model, this paper outlines the classical digital library model, which is derived from traditional practices of library and information science professionals. These practices include the selection and organization of information resources for local populations of users and the integration of advanced information retrieval tools, such as databases and the Internet into these collections. To evaluate this model, library and information professionals and endusers involved with primary care medicine were asked to respond to a series of questions comparing their experiences with a digital library developed for the primary care population to their experiences with general Internet use. Preliminary results are reported

    Abstract
    Thomson ISI has announced the Century of Science initiative. Currently, Web of Science coverage extends to 1945. The Century of Science initiative will expand the Web of Science to include bibliographic data from the highest impact scientific literature published between 1944 and 1900, adding nearly 850,000 articles from approximately 200 journals. The jour-nals have been carefully selected by the Thomson ISI editorial team, based an such criteria as citation patterns, geographic origin, and meaningful balance across scientific disciplines. The Century of Science initiative will extend through 2004, with the new material available to customers in 2005. Using the historical data that will be available, researchers will be able to track published research concepts retrospectively back to the beginning of the 20th century and consequently develop a greater understanding of prior developments. Currently, Web of Science indexes approximately 8,500 scholarly journals, providing users with complete bibliographic data, searchable author abstracts, and cited references. Web of Science is a key component of ISI Web of Knowledge, the single Web environment from which researchers can access, analyze, and manage information. Thomson ISI (http: //www.thomsonisi.com) is a business of Thomson Scientific, part of The Thomson Corp.

    Abstract
    In the case of health information the quality and authenticity of the digital information have always been a matter of major concern for health and information professionals. This paper seeks to explore these concerns from the consumers' perspective. It addresses issues around the consumers' trust of health information. An online questionnaire was used to gather the data. Over a period of three weeks more than 1,300 people responded to the online questionnaire produced by The British Life and Internet Project: 81 per cent or 997 of the respondents were from the UK. A major finding was that half the respondents believed only some or even none of the health information found on the web and 45 per cent said that they had found misleading health information. This was found to be truer for respondents who surfed around. Thus respondents who used five or more sites to inform them were more likely to have found misleading information. Finally, data are presented to show that data collected from another independent study, conducted on behalf of the Department of Health, come to many of the same conclusions.

    Abstract
    The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an "edit'' button. The open nature of the Wikipedia has been key to its success, but has a flip side: if anyone can edit, how can readers know whether to trust its content? To help answer this question, we have developed a reputation system for Wikipedia authors, and a trust system for Wikipedia text. Authors gain reputation when their contributions are long-lived, and they lose reputation when their contributions are undone in short order. Each word in the Wikipedia is assigned a value of trust that depends on the reputation of its author, as well as on the reputation of the authors that subsequently revised the text where the word appears. To validate our algorithms, we show that reputation and trust have good predictive value: higher-reputation authors are more likely to give lasting contributions, and higher-trust text is less likely to be edited. The trust can be visualized via an intuitive coloring of the text background. The coloring provides an effective way of spotting attempts to tamper with Wikipedia information. A trust-colored version of the entire English Wikipedia can be browsed at http://trust.cse.ucsc.edu/

    Abstract
    Currently, web document repositories have been collaboratively created and edited. One of these repositories, Wikipedia, is facing an important problem: assessing the quality of Wikipedia. Existing approaches exploit techniques such as statistical models or machine leaning algorithms to assess Wikipedia article quality. However, existing models do not provide satisfactory results. Furthermore, these models fail to adopt a comprehensive feature framework. In this article, we conduct an extensive survey of previous studies and summarize a comprehensive feature framework, including text statistics, writing style, readability, article structure, network, and editing history. Selected state-of-the-art deep-learning models, including the convolutional neural network (CNN), deep neural network (DNN), long short-term memory (LSTMs) network, CNN-LSTMs, bidirectional LSTMs, and stacked LSTMs, are applied to assess the quality of Wikipedia. A detailed comparison of deep-learning models is conducted with regard to different aspects: classification performance and training performance. We include an importance analysis of different features and feature sets to determine which features or feature sets are most effective in distinguishing Wikipedia article quality. This extensive experiment validates the effectiveness of the proposed model.

    Abstract
    The OCLC Authority File is one of the most underused and underrated yet most powerful tool for answering reference questions. It provides the benefits of no cost searching, access to a wealth of biographical and geographical information online, increased staff productivity by reducing research time, multiple cross reference access points, and documenting sources used to verify the information. The flexible searching protocol and the consolidation in one record of both the authorized and all variant forms for personal, corporate, and geographical names, subject headings, and uniform titles (created by the Library of Congress and the National Coordinated Cataloguing Operations (NACO)) mean that searchers need know only one of the forms to retrieve the established heading

    Abstract
    Reviews the main features of Computer Select: a CD-ROM database from Ziff Communications, Co., New York, which provides the full text of over 60 computer periodicals and is designed to enable users of information on software and suppliers, of the type found in 'PC magazine', but which is difficult to find by browsing printed copies of such periodicals. A librarian's perspective is provided by the critical comments of Kathrin Hoover, corporate librarian of Electronic Data Systems, Texas. Concludes that the annual subscription of $ 700,- is high and there are some desirable feature lacking, but rates Computer Select as unparalleled as a tool for finding information rapidly

    Abstract
    The proliferation of electronic information sources has added new dimensions to building library reference collections. As reference librarians select titles for their collections, they must also choose the most appropriate medium. For some information the choices include print, microforms, CD-ROM databases, online hosts, or locally mounted databases. Factors involved in the selection of the appropriate medium include database costs, licensing agreements, hardware/software requirements, retrieval modes, system capabilities and information transfer. Integrating the new services into existing structures so that library users can derive the maximum benefit from the availability of the databases is a primary concern

    Abstract
    Considers the issue of point of use user training for users of CD-ROM databases including consideration of whether any such instruction should be provided; whether only minimal instruction should be provided; how library or user type may influence levels of service; and how to balance the reference desk demands in the age of proliferating CD-ROM databases. Concludes that it is unrealistic to expect to place a definite time limit on point of use user training for CD-ROMs, apart from eliminating it altogether. Recognition of the need to balance CD-ROM point of use training with other reference services should help libraries to come closer to the ideal of a prioritized library service

    Abstract
    Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths

    Abstract
    The multimedia CD-ROM database, Compton's interactive encyclopedia, by Compton's NewMedia, incorporates virtual workspace: a new user interface that is based on Windows and enables searchers to research large amounts of data ba acting as a Windows shell to turn the boundaries of a computer screen into a nearly infinite working display. Users can extract information from a database and place it in a window on the computer screen's 'desktop' and the desktop can be scanned with a mouse, like a magnifying glass, moving from window to window. Notes other features of the database including: the SmarTrieve retrieval engine and the AudioVisual Interleave enhanced sound and animation capability

    Abstract
    Describes the development of Encarta: a multimedia CD-ROM based encyclopaedia database, designed to work with the Microsoft Windows 3.1 operating system, and based on the text of the 29 volume Funk and Wagnalls New Encyclopedia. Encarta contains over 14.000 media elements: including more than 5.000 photographs, scores of illustrations, maps and over 100 animations. Many computer science and pop culture articles have been added to the original text. A major feature is the inclusion of over 7 hours of high quality 16 bit sound with examples of music from around the world, foreign language samples, nature and wild animal sounds, literary readings and speeches, and jazz and classical music samples. For a thorough review of this database see the review article in this issue: CD-ROM world 8(1993) no.6, S.51-55

    Abstract
    Contribution to an issue devoted to the weeding and maintenance of reference collections. Little has been published about weeding reference collections until the past few years and little of that has been empirical research. Reviews the literature on the subject with emphasis on use of the material as a condition for deselection. The University of Wisconsin, Eau Claire Library has collected data for 5 years; Uses this data to show that even in well weeded collections, which previously depended upon subjective methods, empirical data will prove beneficial. Proper reference collection management requires more than subjective judgments. Empirical data may provide a number of surprises. Data collection is being made easier by automation.

    Abstract
    Illustrates how a public library reference service that aims to utilise all types of information resources, both traditional and electronic, increases the options available to users but at the same time risks the emergence of 'Chaotic' situations, arising from inadequate training of the librarian; damage to or misuse of equipment by users; breaches of copyright; or the unforeseen hidden costs involved in Internet based resources. Discusses the 2 levels of training needed by electronic reference librarians; the essential knowledge they require; the pros and cons of reference service fee charging; and the problem of finding the right balance between CD-ROM and Internet resources

    Abstract
    In grauer Vorzeit, also vor etwa 5 Jahren, kostete eine gute Enzyklopädie noch Tausende. Inzwischen sind die ledernen Boliden hierzulande zwar noch nicht billiger geworden, aber wohlfeile Silberscheiben übernehmen Marktanzteile. Wird der Wissensdurst für hundert Mark wirklich schlechter gelöscht als für fünftausend? Oder sind die gedruckten Schwarten bloß noch repräsentatives Accessoire für den Bildungsprotz?

    Abstract
    1997 saw fierce competition among the publishers of print, CD-ROM and online telephone directories in the USA. Considers whether it is worth buying any white pages CD-ROM now that such information is freely available over the Internet. compares 3 versions of the white pages information based on American Business Information (ABI) data: American Directory Assistance (Http://www.lookupusa.com); InfoSpace (http://www.infospace.com); and the 7-disc CD-ROM database PhoneSearch 3.0. Concludes that for casual use such as looking up names, the Web databases are much more efficient. The CD-ROM version may be better for those who regularly want to compile mailing lists and phone lists to target a district
