    Abstract
    Der Aufbau der Europäischen Digitalen Bibliothek wurde im Herbst 2007 auf soliden Grund gestellt: Mit der European Digital Library Foundation steht eine geschäftsfähige Organisation als Trägerin der Europäischen Digitalen Bibliothek zur Verfügung. Sie fungiert zunächst als Steuerungsgremium für das EU-finanzierte Projekt EDLnet und übernimmt sukzessive die Aufgaben, die für den Aufbau und die Weiterentwicklung der Europäischen Digitalen Bibliothek notwendig sind. Die Gründungsmitglieder sind zehn europäische Dachorganisationen aus den Bereichen Bibliothek, Archiv, audiovisuelle Sammlungen und Museen. Vorstandsmitglieder sind die Vorsitzende Elisabeth Niggemann (CENL) die Vize-Vorsitzende Martine de Boisdeffre (EURBICA), der Schatzmeister Edwin van Huis (FIAT) sowie Wim van Drimmelen, der Generaldirektor der Koninklijke Bibliotheek, der Nationalbibliothek der Niederlande, welche die Europäische Digitale Bibliothek hostet. Der Prototyp für die Europäische Digitale Bibliothek wird im Rahmen des EDLnet-Projekts entwickelt. Die erste Version des Prototyps wurde auf der internationalen Konferenz »One more step towards the European Digital Library« vorgestellt, die am 31. Januar und 1. Februar 2008 in der Deutschen Nationalbibliothek (DNB) in Frankfurt am Main stattfand. Die endgültige Version des Prototyps wird im November 2008 von der EU-Kommissarin für Informationsgesellschaft und Medien, Viviane Reding, in Paris vorgestellt werden. Dieser Prototyp wird direkten Zugang zu mindestens zwei Mio. digitalisierten Büchern, Fotografien, Karten, Tonaufzeichnungen, Filmaufnahmen und Archivalien aus Bibliotheken, Archiven, audiovisuellen Sammlungen und Museen Europas bieten.
    Content
    Darin u.a. "Interoperabilität als Kernstück - Technische und semantische Interoperabilität bilden somit das Kernstück für das Funktionieren der Europäischen Digitalen Bibliothek. Doch bevor Wege gefunden werden können, wie etwas funktionieren kann, muss zunächst einmal festgelegt werden, was funktionieren soll. Hierfür sind die Nutzeranforderungen das Maß aller Dinge, weshalb sich ein ganzes Arbeitspaket in EDLnet mit der Nutzersicht, den Nutzeranforderungen und der Nutzbarkeit der Europäischen Digitalen Bibliothek befasst, Anforderungen formuliert und diese im Arbeitspaket »Interoperabilität« umgesetzt werden. Für die Entscheidung, welche Inhalte wie präsentiert werden, sind jedoch nicht allein technische und semantische Fragestellungen zu klären, sondern auch ein Geschäftsmodell zu entwickeln, das festlegt, was die beteiligten Institutionen und Organisationen in welcher Form zu welchen Bedingungen zur Europäischen Digitalen Bibliothek beitragen. Auch das Geschäftsmodell wird Auswirkungen auf technische und semantische Interoperabilität haben und liefert die daraus abgeleiteten Anforderungen zur Umsetzung an das entsprechende Arbeitspaket. Im EDLnet-Projekt ist somit ein ständiger Arbeitskreislauf installiert, in welchem die Anforderungen an die Europäische Digitale Bibliothek formuliert, an das Interoperabilitäts-Arbeitspaket weitergegeben und dort umgesetzt werden. Diese Lösung wird wiederum an die Arbeitspakete »Nutzersicht« und »Geschäftsmodell« zurückgemeldet, getestet, kommentiert und für die Kommentare wiederum technische Lösungen gesucht. Dies ist eine Form des »rapid prototyping«, das hier zur Anwendung kommt, d. h. die Funktionalitäten werden schrittweise gemäß des Feedbacks der zukünftigen Nutzer sowie der Projektpartner erweitert und gleichzeitig wird der Prototyp stets lauffähig gehalten und bis zur Produktreife weiterentwickelt. Hierdurch verspricht man sich ein schnelles Ergebnis bei geringem Risiko einer Fehlentwicklung durch das ständige Feedback."

    Abstract
    Die »Düsseldorfer Virtuelle Bibliothek« (DVB) war nicht nur die erste, sondern in den Neunzigerjahren des vergangenen Jahrhunderts auch die größte wissenschaftliche virtuelle Universalbibliothek im deutschsprachigen Internet. Die beim Aufbau und der Pflege gesammelten Erfahrungen könnten auch für die derzeit entstehenden Virtuellen Fachbibliotheken von Nutzen sein, wie Thomas Hilberer im folgenden Beitrag erklärt.

    Abstract
    The current subject gateways have evolved over time when the discipline of Internet resource discovery was in its infancy. This is reflected by the lack of well-established, light-weight, deployable, easy-to-use, standards for metadata and information retrieval. We provide an introduction to the architecture, standards and software solutions in use by subject gateways, and to the issues that must be addressed to support future subject gateways

    Abstract
    Purpose - To investigate ways of demonstrating how portal implementations positively alter user information retrieval behaviour. Design/methodology/approach - An opinion piece reflecting on existing evidence about the nature of portal implementations, which extrapolates trends in user behaviour on the basis of these reflections. Findings - Although portal technologies probably do offer a way for libraries to create information tools that can compete with "one-stop shop" Internet search engines, there are likely difficulties in their pattern of usage which will have to be detected by effective quality measurement techniques. Research limitations/implications - An expression of opinion about the possible pitfalls of using portals to optimise users' information retrieval activity. Practical implications - This opinion piece gives some clear and practical guidelines for the evaluation of the success of library portal implementations. Originality/value - This editorial points out that, because the portal can be defined as a deliberate clone of a typical successful Internet search engine and may be presented to the naïve user in the same terms, the danger is that library portals might also clone the same information habits as Internet search engines, because of their ease of use. In trying to produce a tool that can meet Google on its own terms but with better content, we might reproduce some of the same educational disbenefits as Google: quality information retrieval is not purely a function of content, it is also a function of the user's perceptions and information habits.

    Abstract
    The following describes a number of technologies and exemplary service designs that foster better Internet finding tools in libraries and more cooperative and efficient effort in Internet resource collection building. Our library and partner institutions have been involved in this work for over a decade. The open source software and projects discussed represent appropriate technologies and sustainable strategies that will help Internet portals, digital libraries, virtual libraries and library catalogs-with-portal-like-capabilities (IPDVLCs) to scale better and to anticipate and meet the needs of scholarly and educational users.

    Abstract
    This article gives an overview of the design and organisation of DutchESS, a Dutch information subject gateway created as a national collaborative effort of the National Library and a number of academic libraries. The combined centralised and distributed model of DutchESS is discussed, as well as its selection policy, its metadata format, classification scheme and retrieval options. Also some options for future collaboration on an international level are explored

    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
    The German Internet Clearinghouse SocioGuide has changed to a database management system. Accordingly the metadata description scheme has become more detailed. The main information types are: institutions, persons, literature, tools, data sets, objects, topics, processes and services. Some of the description elements, such as title, resource identifier, and creator are universal, whereas others, such as primary/secondary information, and availability are specific to information type and cannot be generalized by referring to Dublin Core elements. The quality of Internet sources is indicated implicitly by characteristics, such as extent, restriction, or status. The SocioGuide is managed in DBClear, a generic system that can be adapted to different source types. It makes distributed input possible and contains workflow components.

    Since the 1960s, librarians have projected a vision of a digital library that offers seamless access to a vast world of scholarly information of all types. Until the 1990s, however, digital technologies lacked the power and capacity to deliver on the vision. During the 1990s, technology platforms, networking technologies, electronic resources, and the evolution of standards matured sufficiently to lay the foundation for the vision to be fulfilled. As this maturation was taking place, the rapid growth of electronic resources was based on numerous proprietary systems making access across such systems impossible. The scholars portal project is an effort to create a search and retrieval tool that will provide an interim solution to this problem until such time as those systems are built on a unified set of standards and data formats.

    Abstract
    This article describes the journey from the conception of and vision for a modern search-engine-based search environment to its technological realisation. In doing so, it takes up the thread of an earlier article on this subject, this time from a technical viewpoint. As well as presenting the conceptual considerations of the initial stages, this article will principally elucidate the technological aspects of this journey. The starting point for the deliberations about development of an academic search engine was the experience we gained through the generally successful project "Digital Library NRW", in which from 1998 to 2000-with Bielefeld University Library in overall charge-we designed a system model for an Internet-based library portal with an improved academic search environment at its core. At the heart of this system was a metasearch with an availability function, to which we added a user interface integrating all relevant source material for study and research. The deficiencies of this approach were felt soon after the system was launched in June 2001. There were problems with the stability and performance of the database retrieval system, with the integration of full-text documents and Internet pages, and with acceptance by users, because users are increasingly performing the searches themselves using search engines rather than going to the library for help in doing searches. Since a long list of problems are also encountered using commercial search engines for academic use (in particular the retrieval of academic information and long-term availability), the idea was born for a search engine configured specifically for academic use. We also hoped that with one single access point founded on improved search engine technology, we could access the heterogeneous academic resources of subject-based bibliographic databases, catalogues, electronic newspapers, document servers and academic web pages.

    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
    The paper gives a short overview of the history of use of UDC in Internet subject gateways (SGs) with an English interface, from 1993 to 2006. There were in total, nine quality controlled SGs that were functional for shorter or longer periods of time. Their typology and functionality is described. Quality SGs have evolved and the role of classification has changed accordingly from supporting subject organization on the interface and automatic categorization of resources, towards supporting a semantic linking, control and vocabulary mapping between different indexing systems in subject hubs and federated SGs. In this period, many SGs ceased to exist and little information remains available regarding their status. SGs currently using UDC, for some part of their resource organization, do not use a UDC subject hierarchy at the interface and its role in resource indexing has become more difficult to observe. Since 2000, UDC has become more prevalent in East European SGs, portals and hubs, which are outside the scope of this research. This paper is an attempt to provide a record on this particular application of UDC and to offer some consideration of the changes in requirements when it comes to the use of library classification in resource discovery.

    Abstract
    Clearinghouses - or subject gateways - are domain-specific collections of links to resources an the Internet. The links are described with metadata and structured according to a domain-specific subject hierarchy. Users access the information by searching in the metadata or by browsing the subject hierarchy. The standards for metadata vary across existing Clearinghouses and different technologies for storing and accessing the metadata are used. This makes it difficult to distribute the editorial or administrative work involved in maintaining a clearinghouse, or to exchange information with other systems. DBClear is a generic, platform-independent clearinghouse system, whose metadata schema can be adapted to different standards. The data is stored in a relational database. It includes a workflow component to Support distributed maintenance and automation modules for link checking and metadata extraction. The presentation of the clearinghouse an the Web can be modified to allow seamless integration into existing web sites.
