    Abstract
    This study examines the differences between Scopus and Web of Science in the citation counting, citation ranking, and h-index of 22 top human-computer interaction (HCI) researchers from EQUATOR - a large British Interdisciplinary Research Collaboration project. Results indicate that Scopus provides significantly more coverage of HCI literature than Web of Science, primarily due to coverage of relevant ACM and IEEE peer-reviewed conference proceedings. No significant differences exist between the two databases if citations in journals only are compared. Although broader coverage of the literature does not significantly alter the relative citation ranking of individual researchers, Scopus helps distinguish between the researchers in a more nuanced fashion than Web of Science in both citation counting and h-index. Scopus also generates significantly different maps of citation networks of individual scholars than those generated by Web of Science. The study also presents a comparison of h-index scores based on Google Scholar with those based on the union of Scopus and Web of Science. The study concludes that Scopus can be used as a sole data source for citation-based research and evaluation in HCI, especially when citations in conference proceedings are sought, and that researchers should manually calculate h scores instead of relying on system calculations.

    Abstract
    By Internet resources Zhang means any electronic file accessible by any Internet protocol. Their usage is determined by an examination of the citations to such sources in a nine-year sample of four print and four electronic LIS journals, by a survey of editors of these journals, and by a survey of scholars with "in press" papers in these journals. Citations were gathered from Social Science Citation Index and manually classed as e-sources by the format used. All authors with "in press" papers were asked about their use and opinion of Internet sources and for any suggestions for improvement. Use of electronic sources is heavy and access is very high. Access and ability explain most usage while satisfaction was not significant. Citation of e-journals increases over the eight years. Authors report under citation of e-journals in favor of print equivalents. Traditional reasons are given for citing and not citing, but additional reasons are also present for e-journals.

    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.

    Abstracts and indexes have been migrating from print to digital for over 2 decades but original full text records, both text and image, are available in a variety of media. Producers of fully electronic journals are planning to index their content rather than rely on full text browsing, even with more powerful search engines. Reviews UMI's ProQuest on CD-ROM, a combination of HW Wilson Applied Science and Technology Abstracts (AST) and full text images of the original articles. The product is currently for DOS with a Windows version planned. Discusses searching and problems

    Abstract
    In 1997 a survey was held in the Netherlands by the Innovatie Wetenschappelijke Informatievoorziening (Innovation in Scientific Information Services) Steering Group to establish how much use students and research workers make of the Internet. 84% of respondents reported it useful for email communication, whilst 49% used it for consulting web documents. However, only 27% of respondents used it to consult electronic journals. A majority of respondents asked for greater assistance from library staff

    Abstract
    The proliferation of electronic databases and reduced library collections require researchers to be familiar with an increasing range of bibliographical resources. To assist users in searching multiple databases the PICA network in the Netherlands has developed PiCarta as a single information source. The servie enables users to access bibliographical databases and electronic journals using Boolean logic, fuzzy operators, and subject weighting. The system is, however, dependent upon indexing methods used in original sources

    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
    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
    Describes the INSPEC database, claimed to be the world's largest English language bibliographic database, as well as the most comprehensive available for physics, electronics and computing. Traces the development of 'Science Abstracts' from its 1st issue published in Jan 1898 which contained 110 abstracts: 1.423 were included during this initial year. Examines subsequent growth and development, emphasizing the commitment to quality, extension of the Physics coverage, the CD-ROM database and the total of 5,75 million records included at the end of 1997. Current growth is 300.000 records per year, from over 4.000 journals and serials, plus 2.000 conference proceedings and other materials

    Abstract
    Reviews the exponential growth of Internet resources leading to the emergence of hundreds of Internet directories to organize those resources. Based upon their format, content, and characteristics, these Internet directories are categorized into 8 groups. From one of these groups. 'Subject directories published in professional journals' all published Internet directories are identified and listed in detail. Using Paradox-For-Windows, a comprehensive database of more than 350 of these directories was developed. Analyzes and interprets the data contained in the database and reviews the strengths and weaknesses of print Internet subject directories as compared to online directories and other search engines

    Abstract
    The paper is based an the database "E-journals Library" ("Elektronische Zeitschriftenbibliothek" - EZB). http://www.bibliothek.uni-regensburg.de/ezeit/. This database was developed by the University Library of Regensburg to offer a user-friendly interface independent of publishers' websites (like ScienceDirect). The main criterion for the service is real usage, not descriptive cataloging. The system is a web-based service, a dedicated system, outside the traditional catalogue. What are the functions of such a dedicated system? If we want to bring users to our digital libraries we should ask what they want from such a library and which service we should offer. 1. Content: as much as possible and highly relevant content. 2. Tools to search and browse for the content wanted. Browsing in a digital library is comparable to browsing in a reading room. 3. The digital library should have a clear profile of content. If these criteria coincide, the usage can be high. In the case of EZB it will be 4,000,000 users this year. The service is growing steadily, corresponding to the increasing supply of electronic jounals and the increasing acceptance of digital publications. When I compare such a dedicated system with a reading room, I want to say: "There are different functions necessary compared to a collection of printed books. The EZB is not merely a catalogue; it has the functions of a virtual reading room, which are quite different from an OPAC. Another question is: what is necessary to present electronic journals? This material is different from monographs, which are normally highly specialized. The purpose of this paper is to show the different methods of access which are offered to the user and which methods are used most.
