    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
    This article describes an approach for linking geographically distributed collections of metadata so that they are searchable as a single collection. We describe the infrastructure, which uses standard Internet protocols such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP), to distribute queries, return results, and exchange index information. We discuss the advantages of using linked collections of authoritative metadata as an alternative to using a keyword indexing search-engine for resource discovery. We examine other architectures that use metadata for resource discovery, such as Dienst/NCSTRL, the AHDS HTTP/Z39.50 Gateway, and the ROADS initiative. Finally, we discuss research issues and future directions of the project. The Internet Scout Project, which is funded by the National Science Foundation and is located in the Computer Sciences Department at the University of Wisconsin-Madison, is charged with assisting the higher education community in resource discovery on the Internet. To that end, the Scout Report and subsequent subject-specific Scout Reports were developed to guide the U.S. higher education community to research-quality resources. The Scout Report Signpost utilizes the content from the Scout Reports as the basis of a metadata collection. Signpost consists of more than 2000 cataloged Internet sites using established standards such as Library of Congress subject headings and abbreviated call letters, and emerging standards such as the Dublin Core (DC). This searchable and browseable collection is free and freely accessible, as are all of the Internet Scout Project's services.
    As well developed as both the Scout Reports and Signpost are, they cannot capture the wealth of high-quality content that is available on the Internet. An obvious next step toward increasing the usefulness of our own collection and its value to our customer base is to partner with other high-quality content providers who have developed similar collections and to develop a single, virtual collection. Project Isaac (working title) is the Internet Scout Project's latest resource discovery effort. Project Isaac involves the development of a research testbed that allows experimentation with protocols and algorithms for creating, maintaining, indexing and searching distributed collections of metadata. Project Isaac's infrastructure uses standard Internet protocols, such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP) to distribute queries, return results, and exchange index or centroid information. The overall goal is to support a single-search interface to geographically distributed and independently maintained metadata collections.

    Abstract
    Specifically designed for core units in library automation and information systems, this long awaited new text gives students a comprehensive overview of one of the most critical areas of library operations. Produced by two internationally known scholars, Thomas Kochtanek and Joseph Matthews, this book will enable students to take the lead in managing an immense diversity of information resources and at the same time handle the complexities that information technology brings to the library. Giving important insight into library information systems-from the historical background to the latest technological trends and developments-the book is organized into 14 chapters, each presenting helpful information on such topics as systems design, types of systems, coverage of standards and standards organizations, technology axioms, system selection and implementation, usability of systems, library information systems management, technology trends, digital libraries, and more. New to the acclaimed Library and Information Science Text Series, this book will prove an indispensable resource to students preparing for a career in today's ever-evolving library environment. Complete with charts and illustrations, chapter summaries, suggested print and electronic resources, a glossary of terms, and an index, this text will be of central importance to libraries and library schools everywhere.

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
