    Abstract
    Special classifications have been somewhat neglected in KO compared to general classifications. The methodology of constructing special classifications is important, however, also for the methodology of constructing general classification schemes. The methodology of constructing special classifications can be regarded as one among about a dozen approaches to domain analysis. The methodology of (special) classification in LIS has been dominated by the rationalistic facet-analytic tradition, which, however, neglects the question of the empirical basis of classification. The empirical basis is much better grasped by, for example, bibliometric methods. Even the combination of rational and empirical methods is insufficient. This presentation will provide evidence for the necessity of historical and pragmatic methods for the methodology of classification and will point to the necessity of analyzing "paradigms". The presentation covers the methods of constructing classifications from Ranganathan to the design of ontologies in computer science and further to the recent "paradigm shift" in classification research. 1. Introduction Classification of a subject field is one among about eleven approaches to analyzing a domain that are specific for information science and in my opinion define the special competencies of information specialists (Hjoerland, 2002a). Classification and knowledge organization are commonly regarded as core qualifications of librarians and information specialists. Seen from this perspective one expects a firm methodological basis for the field. This paper tries to explore the state-of-the-art conceming the methodology of classification. 2. Classification: Science or non-science? As it is part of the curriculum at universities and subject in scientific journals and conferences like ISKO, orte expects classification/knowledge organization to be a scientific or scholarly activity and a scientific field. However, very often when information specialists classify or index documents and when they revise classification system, the methods seem to be rather ad hoc. Research libraries or scientific databases may employ people with adequate subject knowledge. When information scientists construct or evaluate systems, they very often elicit the knowledge from "experts" (Hjorland, 2002b, p. 260). Mostly no specific arguments are provided for the specific decisions in these processes.

    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    A subject gateway, in the context of network-based resource access, can be defined as some facility that allows easier access to network-based resources in a defined subject area. The simplest types of subject gateways are sets of Web pages containing lists of links to resources. Some gateways index their lists of links and provide a simple search facility. More advanced gateways offer a much enhanced service via a system consisting of a resource database and various indexes, which can be searched and/or browsed through a Web-based interface. Each entry in the database contains information about a network-based resource, such as a Web page, Web site, mailing list or document. Entries are usually created by a cataloguer manually identifying a suitable resource, describing the resource using a template, and submitting the template to the database for indexing. Subject gateways are also known as subject-based information gateways (SBIGs), subject-based gateways, subject index gateways, virtual libraries, clearing houses, subject trees, pathfinders and other variations thereof. This paper describes the characteristics of some of the subject gateways currently accessible through the Web, and compares them to automatic "vacuum cleaner" type search engines, such as AltaVista. The application of WHOIS++, centroids, query routing, and forward knowledge to searching several of these subject gateways simultaneously is outlined. The paper concludes with looking at some of the issues facing subject gateway development in the near future. The paper touches on many of the issues mentioned in a previous paper in D-Lib Magazine, especially regarding resource-discovery related initiatives and services.

Damit ist BASE nach Google Scholar die größte Suchmaschine für wissenschaftliche, frei im Internet verfügbare Dokumente. Für über 30 Mio. Dokumente, die in BASE zu finden sind, können wir aufgrund von Informationen in den Metadaten einen Open-Access-Status ausweisen, insgesamt schätzen wir den Open-Access-Anteil derzeit auf 60%. Über ein Boosting-Verfahren werden Nachweise zu Open-Access-Dokumenten bevorzugt angezeigt, ebenso ist ein gezieltes Suchen unter Berücksichtigung verschiedener Lizenz- und Rechteangaben möglich. Der BASE-Index steht über verschiedene Schnittstellen zahlreichen anderen kommerziellen und nicht-kommerziellen Discovery-Systemen, Suchmaschinen, Datenbankanbietern, Fachbibliotheken und Entwicklern zur Nachnutzung zur Verfügung. BASE trägt damit wesentlich zur Nutzung von Inhalten auf Dokumentservern bei. Weitere Informationen: https://www.base-search.net/

    Abstract
    Im Januar 2004 wurde das EU-Projekt »The European Library (TEL)« erfolgreich beendet: Die Errichtung einer virtuellen europäischen Nationalbibliothek hat sich als machbar erwiesen. Die Arbeit im TEL-Projekt wurde im Februar 2001 aufgenommen und konzentrierte sich auf folgende Schwerpunkte: - Untersuchung der Möglichkeiten, Vereinbarungen mit Verlegern über die europaweite Bereitstellung elektronischer Publikationen über die Nationalbibliotheken zu erzielen, - Herstellen eines Konsenses unter den beteiligten Partnern über das angestrebte gemeinsame Serviceangebot sowie die Erstellung eines für alle akzeptablen Geschäftsmodells für die Entwicklung, das Management und die Finanzierung dieses Serviceangebots, - Erstellung eines abgestimmten, für weitere Entwicklungen offenen Metadaten-Modells für das geplante Serviceangebot, - Entwicklung und Test einer technischen Umgebung, welche den integrierten Zugang zu den Daten der Partner sowohl über Z39.50 als auch über einen zentralen, XML-basierten Index ermöglicht. Die Ergebnisse des TEL-Projektes sind ein Geschäftsmodell, ein Metadatenmodell sowie eine technische Lösung für die Integration von Daten, auf welche über Z39.50 oder über einen zentralen, XML-basierten Index zugegriffen werden kann. Aufgrund dieser Ergebnisse beschlossen die TEL-Partner (die Nationalbibliotheken von Deutschland, Finnland, Großbritannien, Italien, der Niederlande, Portugal, Slowenien und der Schweiz sowie das Istituto Centrale per il Catalogo Unico delle Biblioteche Italia ne e per le Informazioni Bibliografiche ICCU), nach Beendigung der Projektphase TEL als kostenloses Webangebot der europäischen Nationalbibliotheken aufzubauen. Alle Projektpartner erklärten sich bereit, sich an der Umsetzung und Startfinanzierung zu beteiligen. Langfristig ist die Beteiligung aller in der Konferenz der Europäischen Nationalbibliothekare (CENL) vertretenen Nationalbibliotheken geplant. Das TEL-Projekt ist aus der Idee der Weiterentwicklung von Gabriel entstanden, dem Webservice der CENL-Bibliotheken. Im Jahre 1994 beschlossen die Direktorinnen und Direktoren der europäischen Nationalbibliotheken die Einrichtung eines gemeinsamen Online-Forums, um einen schnelleren und einfacheren Austausch über neue Entwicklungen und Aktivitäten in europäischen Bibliotheken zu ermöglichen. Die Idee wurde bald ausgeweitet, sodass nicht nur ein Forum für alle CENL-Mitglieder, sondern auch ein Informationsangebot über CENL, ihre Mitgliedsbibliotheken und deren OnlineDienste als »single point of access« geplant wurde. Die Nationalbibliotheken von Deutschland, Finnland, Frankreich, Großbritannien und den Niederlanden übernahmen die Entwicklung eines prototypischen Webangebots, das sie »Gabriel - Gateway and Bridge to Europe's National Libraries« nannten. Gabriel bietet Informationen auf drei Ebenen: auf der europäischen Ebene über Kooperationsprojekte und internationale Veranstaltungen, auf nationaler Ebene Beschreibungen der Bibliotheken, ihrer Funktionen und ihrer Sammlungen und schließlich auf individueller Ebene die Dienstleistungsangebote der einzelnen Bibliotheken.

    Abstract
    Library and Archives Canada (LAC) has capitalized on the Dewey Decimal Classification (DDC) potential for organizing Web resources in two projects. Since 1995, LAC has been providing a service that offers links to authoritative Web resources about Canada categorized according to the DDC via its Web site. More recently, LAC has partnered with the federal government Department of Canadian Heritage to manage Web content related to Canadian culture in a DDC-based subject tree. Although the DDC works well to organize a broadly-based collection, challenges have been encountered in adapting it for a specific subject domain.

    Abstract
    This paper presents the approach and first results of the classification mapping process in the EU project Renardus. The outcome in Renardus is a cross-browsing feature based an the Dewey Decimal Classification (DDC) and improved subject searching across distributed and heterogeneous European subject gateways. The paper presents the project's initial experiences and decisions, e.g. an investigation of the use of classification systems by Renardus partners' gateways, general mapping approaches and issues, the definition of mapping relationships and some information an technical solutions and the mapping tool. There is also a demonstration of the use of the mapping information in Renardus and the presentation of several features that have been implemented to aid end-user navigation in a large and deep browsing structure like the DDC. Classification mapping for crossbrowsing is a labour intensive and complex effort which at the moment raises many open questions and leaves many more future potential work tasks than completed useful solutions.

    "1. The EU projeet Renardus Renardus is a project funded by the European Commission as part of the Information Society Technologies (IST) programme, part of the European Union's 5th Framework Programme. Partners in Renardus include national libraries, research centres and subject gateway services from Denmark, Finland, Germany, The Netherlands, Sweden and the UK, co-ordinated by the National Library of the Netherlands. The project aims to develop a Web-based service to enable searching and browsing across a range of distributed European-based information services designed for the academic and research communities - and in particular those services known as subject gateways. These gateways are services that provide access to Internet resources. They tend to be selective with regard to the resources they give access to, and are usually based an the manual creation of descriptive metadata. Services typically provide users with both search and browse facilities, and offen offer hierarchical browse structures based an subject classification schemes (Koch & Day, 1997). Predecessor projects like the EU project DESIRE have already developed solutions for the description of individual resources and for automatic classification at the level of an individual subject gateway using established classification systems. Renardus intends to develop a service that can cross-search and cross-browse a number of distributed subject gateways through the use of a common metadata profile and by the mapping all locally-used classification schemes to a common scheme. A thorough review of existing data models (Becker, et al., 2000) was used as the basis for the agreement of a minimum set of Dublin Core-based metadata elements that could be utilised as a common data model. A comprehensive mapping effort from the individual gateways' metadata element sets and content encoding schemes to the common profile has taken place. This provides the infrastructure for interoperability between all participating databases and thus is the necessary prerequisite for cross-searching."
