    Abstract
    The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized

    Abstract
    All types of information can be referenced to a geographic place. Maps, aerial photographs, and remote sensing images are spatially georeferenced. Other forms of information such as books, articles, research papers, pieces of music, and art are often linked to a geographic location through place names (geographic names). A gazetteer (a dictionary of geographic names) that is spatially referenced itself provides the bridge between these two types of georeferencing. With a georeferenced gazetteer translation service, a user can start with a geographic name and find information that is described with either geographic names or with geospatial coordinates. Use of this powerful indirect geospatially referencing tool can be applied as a common approach to libraries, bibliographic files, data centers, web resources, and museum and specimen collections and can be particular useful across language barriers since latitude and longitude coordinates are universally understood. The Alexandria Digital Library has implemented a gazetteer component for its georeferenced digital library. This experience resulted in the creation of a Gazetteer Content Standard, a Feature Type Thesaurus, and an operational interactive gazetteer service. This paper describes the development of these components and illustrates the use of this tool in a georeferenced digital library. It also relates progress in working with Federal agencies and others toward developing shareable gazetteer data through Digital Gazetteer Information Exchange programs

    Abstract
    Purpose Wikipedia has the lofty goal of compiling all human knowledge. The purpose of the present study is to map the structure of the Traditional Chinese Medicine (TCM) knowledge domain on Wikipedia, to identify patterns of knowledge representation on Wikipedia and to test the applicability of author bibliographic coupling analysis, an effective method for mapping knowledge domains represented in published scholarly documents, for Wikipedia data. Design/methodology/approach We adapted and followed the well-established procedures and techniques for author bibliographic coupling analysis (ABCA). Instead of bibliographic data from a citation database, we used all articles on TCM downloaded from the English version of Wikipedia as our dataset. An author bibliographic coupling network was calculated and then factor analyzed using SPSS. Factor analysis results were visualized. Factors were labeled upon manual examination of articles that authors who load primarily in each factor have significantly contributed references to. Clear factors were interpreted as topics. Findings Seven TCM topic areas are represented on Wikipedia, among which Acupuncture-related practices, Falun Gong and Herbal Medicine attracted the most significant contributors to TCM. Acupuncture and Qi Gong have the most connections to the TCM knowledge domain and also serve as bridges for other topics to connect to the domain. Herbal medicine is weakly linked to and non-herbal medicine is isolated from the rest of the TCM knowledge domain. It appears that specific topics are represented well on Wikipedia but their conceptual connections are not. ABCA is effective for mapping knowledge domains on Wikipedia but document-based bibliographic coupling analysis is not. Originality/value Given the prominent position of Wikipedia for both information users and for researchers on knowledge organization and information retrieval, it is important to study how well knowledge is represented and structured on Wikipedia. Such studies appear largely missing although studies from different perspectives both about Wikipedia and using Wikipedia as data are abundant. Author bibliographic coupling analysis is effective for mapping knowledge domains represented in published scholarly documents but has never been applied to mapping knowledge domains represented on Wikipedia.

    Abstract
    Many researchers in medical and life sciences commonly use the PubMed online search engine (http://www.pubmed.gov) to access the MEDLINE bibliographic database. The researchers' strategies were investigated as a function of their knowledge of the content area. Sixteen life science researchers with no experience in neuroscience and 16 neuroscience researchers of matched professional experience performed five bibliographic search tasks about neuroscience topics. Objective measures and concomitant verbal protocols were used to assess behavior and performance. Whatever their knowledge of PubMed, neuroscientists could find adequate references within the allotted time period. Despite their lack of knowledge in neuroscience, life scientists could select adequate references with the same efficiency. However, differences were observed in the way neuroscientists and life scientists proceeded. For instance, life scientists took more time to read the task instructions and opened more abstracts while selecting their answers. These data suggest that regular use of online databases combined with graduate-level expertise in a broad scientific field like biology can compensate for the absence of knowledge in the specific domain in which references are sought. The large inter-individual variability in performance within both groups implies that beyond domain knowledge, individual cognitive abilities are the main determinants of bibliographic search performance.

    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
    Since their inception in the early 1960s the strength and unique aspect of the ISI citation indexes has been their ability to illustrate the conceptual relationships between scholarly documents. When authors create reference lists for their papers, they make explicit links between their own, current work and the prior work of others. The exact nature of these links may not be expressed in the references themselves, and the motivation behind them may vary (this has been the subject of much discussion over the years), but the links embodied in references do exist. Over the past 30+ years, technology has allowed ISI to make the presentation of citation searching increasingly accessible to users of our products. Citation searching and link tracking moved from being rather cumbersome in print, to being direct and efficient (albeit non-intuitive) online, to being somewhat more user-friendly in CD format. But it is the confluence of the hypertext link and development of Web browsers that has enabled us to present to users a new form of citation product -- the Web of Science -- that is intuitive and makes citation indexing conceptually accessible. A cited reference search begins with a known, important (or at least relevant) document used as the search term. The search allows one to identify subsequent articles that have cited that document. This feature adds the dimension of prospective searching to the usual retrospective searching that all bibliographic indexes provide. Citation indexing is a prime example of a concept before its time - important enough to be used in the meantime by those sufficiently motivated, but just waiting for the right technology to come along to expand its use. While it was possible to follow citation links in earlier citation index formats, this required a level of effort on the part of users that was often just too much to ask of the casual user. In the citation indexes as presented in the Web of Science, the relationship between citing and cited documents is evident to users, and a click of the mouse is all it takes to follow a citation link. Citation connections are established between the published papers being indexed from the 8,000+ journals ISI covers and the items their reference lists contain during the data capture process. It is the standardized capture of each of the references included with these documents that enables us to provide the citation searching feature in all the citation index formats, as well as both internal and external links in the Web of Science.

    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    CD-ROMs generate increased questions that require individual instruction, staff training and bibliographic instruction. Many libraries are moving away from CD-ROMs towards locally mounted databases and access to remote databases, but the variety and sheer number of CD-ROMs may guarantee their survival, especially in larger university libraries or special libraries. With increasing services and collections offered, quality reference service may decay. Discusses undergraduates and the learning process and improvements to service instruction and the reference service

    Abstract
    Presents a brief, critical review of LISA PLaus: the CD-ROM database version of LISA and which includes the database of Current Research in Library and Information Science (CRLIS). The review covers the DOS version only, as it appeared in the Summer 1996 CD-ROM, noting that the Windows version was planned for the future. Points to the way LISA has found its mark, if not its fortune, in LISA Plus and notes its strengths, including: ideal suitability for current awareness in library and information science (LIS); massive and convenient consolidation of the published LIS literature; and massive increase in coverage from 7.900 abstracts in 1993 to over 12.000 currently. Criticizes certain features of LISA Plus, notably: the OPTI-Ware search interface; the combination of 2 databases (LISA and CRLIS) in a single, searchable database; and certain unexpected effects caused by the building of the Subject and Free Text indexes. Points particularly to great lack of consistency in the indexes and the indexing (faults that were fully rectified by a complete overhaul of the data in Summer 1996). Notes that LISA Plus is the first port of call for both information researchers and information science students. The Windows version of LISA Plus was launched in Spring 1997

    Abstract
    In zunehmendem Maße finden sich medizinische Informationen ausschließlich im Internet und auf Multimediaprodukten. Dies erhöht die Notwendigkeit einer inhaltlichen Erschließung dieser Medien, die über die Möglichkeiten der Suchmaschinen hinausgeht. Momentan erschließen medizinische Bibliotheken die Neuen Medien mit den traditionellen Mitteln der klassischen Inhaltserschließung konventioneller Medien: systematische Erschließung mit Klassifikationen (NLM-Klassifikation), im Internet meist in der Form strukturierter Listen, und verbale Sacherschließung mit Fachthesaurl (meist MESH oder RSWK), im Internet ergänzt um standardisierte Metadaten (wie Dublin Core DC, Learning Object Data LOD, Platform for Internet Content Selection PICS). Dies geschieht mit großem Aufwand auch deshalb, um eine Kompatibilität der Erschließung und Suchbarkeit von konventionellen und Neuen Medien sicherzustellen, obwohl die Neuen Medien eher wenig und nur in einem bestimmten Kontext genutzt werden. Hängt die geringe Nutzung der Neuen Medien möglicherweise mit einer inadäquaten Evaluierung und Systematisierung zusammen? Vor- und Nachteile der Erschließung der Neuen Medien durch systematische und verbale Klassifikation werden dargestellt. Daraus werden Empfehlungen entwickelt, welchen Anforderungen Erschließungsinstrumente für Neue Medien genügen sollten und welche Konsequenzen sich daraus für die zukünftige Inhaltserschließung Neuer Medien im Sinne einer höheren Nutzbarkeit und Nutzung ergeben (kooperative Erschließung, Bildung von Kompetenzzentren, Entwicklung neuer Erschließungsinstrumente)

    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.
