    Abstract
    The objective of the European Library (TEL) project [TEL] was to set up a co-operative framework and specify a system for integrated access to the major collections of the European national libraries. This has been achieved by successfully applying a new approach for search and retrieval via URLs (SRU) [ZiNG] combined with a new metadata paradigm. One aim of the TEL approach is to have a low barrier of entry into TEL, and this has driven our choice for the technical solution described here. The solution comprises portal and client functionality running completely in the browser, resulting in a low implementation barrier and maximum scalability, as well as giving users control over the search interface and what collections to search. In this article we will describe, step by step, the development of both the search and retrieval architecture and the metadata infrastructure in the European Library project. We will show that SRU is a good alternative to the Z39.50 protocol and can be implemented without losing investments in current Z39.50 implementations. The metadata model being used by TEL is a Dublin Core Application Profile, and we have taken into account that functional requirements will change over time and therefore the metadata model will need to be able to evolve in a controlled way. We make this possible by means of a central metadata registry containing all characteristics of the metadata in TEL. Finally, we provide two scenarios to show how the TEL concept can be developed and extended, with applications capable of increasing their functionality by "learning" new metadata or protocol options.

    Abstract
    The National Science Foundation's (NSF) National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL) program seeks to create, develop, and sustain a national digital library supporting science, mathematics, engineering, and technology (SMET) education at all levels -- preK-12, undergraduate, graduate, and life-long learning. The resulting virtual institution is expected to catalyze and support continual improvements in the quality of science, mathematics, engineering, and technology (SMET) education in both formal and informal settings. The vision for this program has been explored through a series of workshops over the past several years and documented in accompanying reports and monographs. (See [1-7, 10, 12, and 13].) These efforts have led to a characterization of the digital library as a learning environments and resources network for science, mathematics, engineering, and technology education, that is: * designed to meet the needs of learners, in both individual and collaborative settings; * constructed to enable dynamic use of a broad array of materials for learning primarily in digital format; and * managed actively to promote reliable anytime, anywhere access to quality collections and services, available both within and without the network. Underlying the NSDL program are several working assumptions. First, while there is currently no lack of "great piles of content" on the Web, there is an urgent need for "piles of great content". The difficulties in discovering and verifying the authority of appropriate Web-based material are certainly well known, yet there are many examples of learning resources of great promise available (particularly those exploiting the power of multiple media), with more added every day. The breadth and interconnectedness of the Web are simultaneously a great strength and shortcoming. Second, the "unit" or granularity of educational content can and will shrink, affording the opportunity for users to become creators and vice versa, as learning objects are reused, repackaged, and repurposed. To be sure, this scenario cannot take place without serious attention to intellectual property and digital rights management concerns. But new models and technologies are being explored (see a number of recent articles in the January issue of D-Lib Magazine). Third, there is a need for an "organizational infrastructure" that facilitates connections between distributed users and distributed content, as alluded to in the third bullet above. Finally, while much of the ongoing use of the library is envisioned to be "free" in the sense of the public good, there is an opportunity and a need to consider multiple alternative models of sustainability, particularly in the area of services offered by the digital library. More details about the NSDL program including information about proposal deadlines and current awards may be found at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl>.

    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.
