    Abstract
    The Europeana, the European digital library web-service, is being developed in the framework of the EU-funded network EDLnet. The demo version of this webservice was shown at an international conference at the German National Library in Frankfurt on 1 February 2008, the prototype will be launched in November 2008. In November 2007 the EDL Foundation was established to provide cross-domain multilingual access to Europe's cultural heritage. It will facilitate formal agreement across museums, archives, audio-visual archives and libraries on how to cooperate in the delivery and sustainability of a joint portal and will provide a legal framework for use by the EU for funding purposes and as a springboard for future governance. The European Commission is supporting the process towards the Europeana with a set of projects centering on The European Library. This webservice created by the European national libraries is seen as one of the major building blocks of the Europeana.

    Noch nie zuvor war es so leicht, an wissenschaftliche Fachinformation von hoher Qualität zu kommen: Unter www.vascoda.de haben 37 leistungsstarke deutsche Bibliotheken, Forschungsinstitute und Informationseinrichtungen ein fächerübergreifendes Internet-Portal eingerichtet. Es wird als zentrale Anlaufstelle große Mengen an wissenschaftlicher Literatur und Fachinformation online für die Öffentlichkeit zugänglich machen. vascoda bündelt als übergeordnetes Wissenschaftsportal die in Deutschland vorhandenen, mit öffentlichen Mitteln aufgebauten Informationsdienstleistungen unter einer einheitlichen Zugangsoberfläche. Die Suchmaske ist genauso einfach zu handhaben wie die Internet-Suchmaschine Google. Ihre Benutzung ist unentgeltlich. Alle angebotenen Informationen stammen aus geprüften Quellen. Ein Großteil davon ist kostenlos zu beziehen. Es werden aber auch kostenpflichtige Informationen, zum Beispiel aus Verlagsangeboten und kommerziellen Datenbanken, verfügbar gemacht. Um einen schnellen Zugriff auch auf diese Veröffentlichungen zu gewährleisten, soll möglichst viel Information im Einzelverkauf nach Aufruf, dem sogenannten "Pay-per-View"-Verfahren, bereitgestellt werden. Auch vorhandene Abonnements von elektronischen Zeitschriften können weiterhin so genutzt werden, wie es mit dem Verlag oder Informationsanbieter vereinbart ist. Das Bundesministerium für Bildung und Forschung (BMBF) und die Deutsche Forschungsgemeinschaft (DFG) fördern den Aufbau von vascoda gemeinsam. Die Förderer und die an der Informationsallianz beteiligten Partner betrachten das Portal als Grundstein der "Digitalen Bibliothek Deutschland", die sich an den Bedürfnissen der Benutzer orientiert. Zur Zeit sind 23 virtuelle Fachbibliotheken (ViFas), die vier großen Informationsverbünde EconDoc (Wirtschaft), Getlnfo (Naturwissenschaft und Technik), infoconnex (Pädagogik, Sozialwissenschaften, Psychologie und Medizin) sowie die Elektronische Zeitschriftenbibliothek (EZB) in vascoda eingebunden. ViFas - virtuelle Fachbibliotheken - sind Anlaufstellen im Web, die einen Überblick über das fachspezifische Informationsangebot zu bestimmten wissenschaftlichen Fachgebieten geben. Sie wurden in den letzten Jahren mit Unterstützung der DFG aufgebaut, um qualitativ hochwertige Internetquellen, aber auch gedruckte Publikationen - über die Einbindung von Bibliothekskatalogen - leicht zugänglich zu machen. Informationsverbünde bieten ebenfalls Unterstützung bei der Informationssuche. Sie bündeln auf fachlicher Ebene alle Formen relevanter Informationen, um dem Benutzer einen umfassenden Zugang zu ermöglichen. Dabei ist das Angebot von elektronischen Dokumenten in ihrem vollen Wortlaut (Volltext) von zentraler Bedeutung. Das heißt, die gewünschte Information kann sofort im Anschluss an die Suche online auf den eigenen Computer heruntergeladen und ausgedruckt werden.

    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
    Libraries have always been an inspiration for the standards and technologies developed by semantic web activities. However, except for the Dublin Core specification, semantic web and social networking technologies have not been widely adopted and further developed by major digital library initiatives and projects. Yet semantic technologies offer a new level of flexibility, interoperability, and relationships for digital repositories. Kruk and McDaniel present semantic web-related aspects of current digital library activities, and introduce their functionality; they show examples ranging from general architectural descriptions to detailed usages of specific ontologies, and thus stimulate the awareness of researchers, engineers, and potential users of those technologies. Their presentation is completed by chapters on existing prototype systems such as JeromeDL, BRICKS, and Greenstone, as well as a look into the possible future of semantic digital libraries. This book is aimed at researchers and graduate students in areas like digital libraries, the semantic web, social networks, and information retrieval. This audience will benefit from detailed descriptions of both today's possibilities and also the shortcomings of applying semantic web technologies to large digital repositories of often unstructured data.

    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.

    Abstract
    Purpose - The paper aims to argue that digital library retrieval should be based on semantic representations and propose a semantic infrastructure for digital libraries. Design/methodology/approach - The approach taken is formal model based on subject representation for digital libraries. Findings - Search engines and search techniques have fallen short of user expectations as they do not give context based retrieval. Deploying semantic web technologies would lead to efficient and more precise representation of digital library content and hence better retrieval. Though digital libraries often have metadata of information resources which can be accessed through OAI-PMH, much remains to be accomplished in making digital libraries semantic web compliant. This paper presents a semantic infrastructure for digital libraries, that will go a long way in providing them and web based information services with products highly customised to users needs. Research limitations/implications - Here only a model for semantic infrastructure is proposed. This model is proposed after studying current user-centric, top-down models adopted in digital library service architectures. Originality/value - This paper gives a generic model for building semantic infrastructure for digital libraries. Faceted ontologies for digital libraries is just one approach. But the same may be adopted by groups working with different approaches in building ontologies to realise efficient retrieval in digital libraries.

    Abstract
    Digital Libraries currently face the challenge of integrating many different types of research information (e.g. publications, primary data, expert's profiles, institutional profiles, project information etc.) according to their scientific users' needs. To date no general, integrated model for knowledge organization and retrieval in Digital Libraries exists. This causes the problem of structural and semantic heterogeneity due to the wide range of metadata standards, indexing vocabularies and indexing approaches used for different types of information. The research presented in this paper focuses on areas in which activities are being undertaken in the field of Digital Libraries in order to treat semantic interoperability problems. We present a model for the integrated retrieval of factual and textual data which combines multiple approaches to semantic interoperability und sets them into context. Embedded in the research cycle, traditional content indexing methods for publications meet the newer, but rarely used ontology-based approaches which seem to be better suited for representing complex information like the one contained in survey data. The benefits of our model are (1) easy re-use of available knowledge organisation systems and (2) reduced efforts for domain modelling with ontologies.

    Abstract
    The Electronic Cultural Atlas Initiative was formed to encourage scholarly communication and the sharing of data among researchers who emphasize the relationships between place, time, and topic in the study of culture and history. In an effort to develop better tools and practices, The Electronic Cultural Atlas Initiative has sponsored the collaborative development of software for downloading and editing geo-temporal data to create dynamic maps, a clearinghouse of shared datasets accessible through a map-based interface, projects on format and content standards for gazetteers and time period directories, studies to improve geo-temporal aspects in online catalogs, good practice guidelines for preparing e-publications with dynamic geo-temporal displays, and numerous international conferences. The Electronic Cultural Atlas Initiative (ECAI) grew out of discussions among an international group of scholars interested in religious history and area studies. It was established as a unit under the Dean of International and Area Studies at the University of California, Berkeley in 1997. ECAI's mission is to promote an international collaborative effort to transform humanities scholarship through use of the digital environment to share data and by placing greater emphasis on the notions of place and time. Professor Lewis Lancaster is the Director. Professor Michael Buckland, with a library and information studies background, joined the effort as Co-Director in 2000. Assistance from the Lilly Foundation, the California Digital Library (University of California), and other sources has enabled ECAI to nurture a community; to develop a catalog ("clearinghouse") of Internet-accessible georeferenced resources; to support the development of software for obtaining, editing, manipulating, and dynamically visualizing geo-temporally encoded data; and to undertake research and development projects as needs and resources determine. Several hundred scholars worldwide, from a wide range of disciplines, are informally affiliated with ECAI, all interested in shared use of historical and cultural data. The Academia Sinica (Taiwan), The British Library, and the Arts and Humanities Data Service (UK) are among the well-known affiliates. However, ECAI mainly comprises individual scholars and small teams working on their own small projects on a very wide range of cultural, social, and historical topics. Numerous specialist committees have been fostering standardization and collaboration by area and by themes such as trade-routes, cities, religion, and sacred sites.

    Abstract
    cibera als Fachinformationsportal zum spanischen und portugiesischen Sprach-und Kulturraum haben meine Kolleginnen und ich bereits in einem zweiteiligen Bibliotheksdienst-Artikel zur Jahreswende 2005/2006 ausführlich vorgestellt. Im vorliegenden Text geht es nun darum, wie die Staats- und Universitätsbibliothek Hamburg durch die Entwicklung und Umsetzung von Konzepten, die die ViFa in Richtung Web 2.0 erweitern, das Fachportal für die Wissenschaft und die interessierte Öffentlichkeit noch attraktiver gestaltet. "Mitmachweb", "Nutzer dort abholen, wo sie sind" und "Vernetzung mit der Fachcommunity" sind dabei nicht nur theoretische Stichworte, sondern in die Praxis umgesetzte Ziele einer modernen bibliothekarischen Informationsarbeit. Was erwartet Sie in diesem Artikel? Einleitend eine kurze Vorstellung von cibera, gefolgt von allgemeinen Vorüberlegungen, warum es für Virtuelle Fachbibliotheken (und sicher auch für verwandte bibliothekarische Informationsdienste) sinnvoll ist, sich mit dem Thema einer Web-2.0-Implementierung zu beschäftigen. Im Zentrum des Artikels steht dann ein Erfahrungsbericht aus der Praxis. Ein Ausblick darauf, was im Rahmen unserer Zielsetzung, cibera noch stärker mit der Fachcommunity zu vernetzen, im Verlauf des Jahres 2009 noch umgesetzt werden soll, schließt den Artikel ab. Falls Sie Interesse an detaillierteren Informationen haben sollten, hier eine wichtige Bemerkung vorneweg: Ich werde dieses Jahr am Bibliothekartag in Erfurt teilnehmen, sprechen Sie mich also im Vorfeld oder gerne auch vor Ort an, wenn Sie Fragen zu dem Thema Web 2.0 als Chance für die Virtuellen Fachbibliotheken haben.

    Abstract
    The Deutsche Forschungsgemeinschaft (DFG) is the central public funding organization for academic research in Germany. It is thus comparable to a research council or a national research foundation. According to its statutes, DFG's mandate is to serve science and the arts in all fields by supporting research projects carried out at universities and public research institutions in Germany, to promote cooperation between researchers, and to forge and support links between German academic science, industry and partners in foreign countries. In the fulfillment of its tasks, the DFG pays special attention to the education and support of young scientists and scholars. DFG's mandate and operations follow the principle of territoriality. This means that its funding activities are restricted, with very few exceptions, to individuals and institutions with permanent addresses in Germany. Fellowships are granted for work in other countries, but most fellowship programs are restricted to German citizens, with a few exceptions for permanent residents of Germany holding foreign passports.

    Abstract
    Digital libraries are here to stay, and the conversion of traditional to digital is inevitable. Appropriate care should be taken to develop systems and managerial skills as well. Globalisation of the digital concept will not be possible until we overcome the technological gap between developed and developing countries. Measures are needed to overcome the menace of computer viruses and also unauthorised use. Sufficient thought has not been given to attaining self-sustained growth. It is therefore essential to explore new avenues for funding, particularly since initial investment in digital libraries is high, as is maintenance.

    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.

    Abstract
    Librarians have long sought to select, evaluate, and organize information on the Internet. Efforts began with individual librarians sharing bookmark files of favorite sites and progressed to increasingly large, collaboratively produced general and subject/discipline-specific gateway Web sites or megasites. Megasites list major resources usually in a particular subject area or discipline. Library portals that review, evaluate, and sometimes rate and rank resources grew from some of these Web sites. Both megasites and portals serve as gateways to the Internet. Many portals have developed from relatively small static files into large, dynamically generated databases providing descriptive annotations of selected resources and are increasingly overseen as global projects with formal policies and procedures. Portals now provide increasingly complex and sophisticated browse and search capabilities with a multitude of access points, often including call numbers and subject headings. These are described and compared. Future trends such as increased collaboration among portals; automated location, selection, and cataloging of resources; integration of multiple resource types; and increased access to full-content and virtual library services are also discussed.

    Abstract
    Digital libraries have become one of the most important Web services for information seeking. One of their main drawbacks is their global approach: In general, there is just one interface for all users. One of the key elements in improving user satisfaction in digital libraries is personalization. When considering personalizing factors, cognitive styles have been proved to be one of the relevant parameters that affect information seeking. This justifies the introduction of cognitive style as one of the parameters of a Web personalized service. Nevertheless, this approach has one major drawback: Each user has to run a time-consuming test that determines his or her cognitive style. In this article, we present a study of how different classification systems can be used to automatically identify the cognitive style of a user using the set of interactions with a digital library. These classification systems can be used to automatically personalize, from a cognitive-style point of view, the interaction of the digital library and each of its users.

    Abstract
    Results of a project focusing on six Web-based collections in education. Our analysis of homegrown classification structures considers three dimensions. "Structure" is described through quantitative data (e.g. Number of main categories, Number of hierarchical levels, etc.). "Logic" concentrates on two aspects of the subdividing process: division principle, and type of hierarchical relation. "Semantics" relates to concepts and their representation in the form of terms. In our sample, the classification structures are hierarchical, not overly complex and not very specific. The choice, arrangement and sequence of classes are logical. Conceptual and terminological inconsistencies are due to significant gaps in conceptual coverage and lack of terminological control.
