    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
    As an important support tool in science research, specialized information systems are rapidly changing their character. The potential for improvement compared with today's usual systems is enormous. This fact will be demonstrated by means of two problem complexes: - WWW search engines, which were developed without any government grants, are increasingly dominating the scene. Does the WWW displace information centers with their high quality databases? What are the results we can get nowadays using general WWW search engines? - In addition to the WWW and specialized databases, scientists now use WWW library catalogues of digital libraries, which combine the catalogues from an entire region or a country. At the same time, however, they are faced with highly decentralized heterogeneous databases which contain the widest range of textual sources and data, e.g. from surveys. One consequence is the presence of serious inconsistencies in quality, relevance and content analysis. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content development processes via a visual user interface without inconsistencies in content development, for example, seriously impairing the quality of the search results, e. g. when phrasing their search inquiry in the terminology to which they are accustomed
