    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
    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
    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
    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.

    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.
