    Abstract
    Im August 2006 feierte die Redaktion des Fachportals Pädagogik, der Virtuellen Fachbibliothek der Erziehungswissenschaft, das einjährige Bestehen ihres Angebots. Das Fachportal ist der erziehungswissenschaftliche Partner im Rahmen des disziplinübergreifenden Wissenschaftsportals vascoda und wird vom Informationszentrum (IZ) Bildung des Deutschen Instituts für Internationale Pädagogische Forschung (DIPF) in Frankfurt am Main getragen. Aufbau und Entwicklung des Fachportals werden von der Deutschen Forschungsgemeinschaft nach aktuellem Stand bis 2008 gefördert. Seit der Freischaltung im Jahr 2005 konnten seine Informationsangebote erheblich ausgeweitet und in den Zugriffsmöglichkeiten sichtlich optimiert werden. Im Fokus der Darstellung stehen in erster Linie die Angebote an sich, weniger die oft kleinschrittige Funktionsweise der einzelnen Funktionalitäten.

    Abstract
    As digital libraries become a major source of information for many people, we need to know more about how people seek and retrieve information in digital environments. Quite commonly, users with a problem-at-hand and associated question-in-mind repeatedly search a literature for answers, and seek information in stages over extended periods from a variety of digital information resources. The process of repeatedly searching over time in relation to a specific, but possibly an evolving information problem (including changes or shifts in a variety of variables), is called the successive search phenomenon. The study outlined in this paper is currently investigating this new and little explored line of inquiry for information retrieval, Web searching, and digital libraries. The purpose of the research project is to investigate the nature, manifestations, and behavior of successive searching by users in digital environments, and to derive criteria for use in the design of information retrieval interfaces and systems supporting successive searching behavior. This study includes two related projects. The first project is based in the School of Library and Information Sciences at the University of North Texas and is funded by a National Science Foundation POWRE Grant <http://www.nsf.gov/cgi-bin/show?award=9753277>. The second project is based at the Department of Information Studies at the University of Sheffield (UK) and is funded by a grant from the British Library <http://www.shef. ac.uk/~is/research/imrg/uncerty.html> Research and Innovation Center. The broad objectives of each project are to examine the nature and extent of successive search episodes in digital environments by real users over time. The specific aim of the current project is twofold: * To characterize progressive changes and shifts that occur in: user situational context; user information problem; uncertainty reduction; user cognitive styles; cognitive and affective states of the user, and consequently in their queries; and * To characterize related changes over time in the type and use of information resources and search strategies particularly related to given capabilities of IR systems, and IR search engines, and examine changes in users' relevance judgments and criteria, and characterize their differences. The study is an observational, longitudinal data collection in the U.S. and U.K. Three questionnaires are used to collect data: reference, client post search and searcher post search questionnaires. Each successive search episode with a search intermediary for textual materials on the DIALOG Information Service is audiotaped and search transaction logs are recorded. Quantitative analysis includes statistical analysis using Likert scale data from the questionnaires and log-linear analysis of sequential data. Qualitative methods include: content analysis, structuring taxonomies; and diagrams to describe shifts and transitions within and between each search episode. Outcomes of the study are the development of appropriate model(s) for IR interactions in successive search episodes and the derivation of a set of design criteria for interfaces and systems supporting successive searching.

    Abstract
    Virtuelle Quellen zur Kunst-Erschließung und Recherchewar das Thema eines Workshops, der am 16. Oktober 2003 in der Sächsischen Landesbibliothek - Staats- und Universitätsbibliothek Dresden (SLUB) veranstaltet wurde. Anliegen war die Präsentation des DFG-geförderten Projektes ViFaArtVirtuelle Fachbibliothek Gegenwartskunst. Im Folgenden wird dieses Projekt näher vorgestellt. Schwerpunkt der Darstellung wird der hierbei entwickelte Katalog von Webseiten bzw. Internetquellen sein (Art-Guide). Die Auseinandersetzung mit Internetquellen und ihre Nutzung für die Informationsgewinnung ist auch für die Kunstwissenschaft zum aktuellen Thema geworden. Eine Hauptaufgabe des World Wide Web liegt neben dem schnellen und direkten Informationsaustausch in der Vermittlung von Information - einem Hauptanliegen wissenschaftlicher Bibliotheken überhaupt. Somit rückt die Problematik auch immer näher an den Aufgabenkreis von Bibliotheken heran. Es stellen sich Fragen wie: Welche Art von Informationen liegen im Web bereit, sind sie vertrauenswürdig, wie kann man sie nutzen und vor allem: wie sind sie zu finden? Seit 2000 wird an der SLUB eine Virtuelle Fachbibliothek zur Gegenwartskunst projektiert: ViFaArt. Das Projekt ist Partner von Vascoda, dem interdisziplinären Internetportal für wissenschaftliche Information in Deutschland. Unter http:// www.vascoda.de/sind Online- und Print-Informationen von derzeit über 20 Virtuellen Fachbibliotheken, 4 Informationsverbünden und der Elektronischen Zeitschriftenbibliothek (EZB) abrufbar. Anfang des nächsten Jahres wird auch ViFaArt den Katalog der Internetquellen (Art-Guide, vgl. unten) als Datenbank dort einbringen. Eine Metasuche über Vascoda wird dann also immer auch alle ArtGuide-Katalogisate berücksichtigen.

    Abstract
    Über international verfügbare Informationssammlungen wie Datenbanken oder Volltextsammlungen der Bildungsforschung zu informieren und Nutzern die Möglichkeit zu bieten, deren Qualität selbst zu bewerten, ist Aufgabe des im März 2008 begonnenen Projekts "Educational Resources Clearinghouse". Dazu soll auf der Basis semantischer Wiki-Technologien ein Meta-Informationssystem für Bildungsinformationen entwickelt werden. Das Projekt "Educational Resources Clearinghouse" wird im Rahmen des Pakts für Forschung und Innovation 2008 (www.pakt-fuer-forschung.de/) der Leibniz-Gemeinschaft (www.wgl.de/ ?nid=wet&nidap) gefördert und hat eine Laufzeit von zwei Jahren. Formale und inhaltliche Kriterien wie Art der Information, thematische Ausrichtung, Zugangsbedingungen/-restriktionen oder die Sprache, in der die Informationssammlung vorliegt, bilden den Kern der Beschreibungen der im "Educational Resources Clearinghouse" zusammengestellten Informationen. Aber Nutzer sollen sich nicht nur ein zuverlässiges Bild über derartige Sammlungen machen können - das Clearinghouse soll ihnen insbesondere auch als Ausgangspunkt für die kollektive Diskussion und Weiterentwicklung des Informationsangebots dienen. Im Sinne des so genannten "Kollaborativen Tagging" können sie Qualitätskriterien selbst benennen und deren Relevanz beurteilen. Die qualitative Beurteilung erfolgt also in einem offenen lnformations- und Kommunikationsraum. Mithilfe von Semantic MediaWiki, einer Erweiterung der MediaWiki-Software, werden die Beschreibungen und Beurteilungen der Informationssammlungen zu semantischen Analysen genutzt. Ziel ist es, die Informationen zueinander in Beziehung zu setzen und damit automatisch neues Wissen zu generieren. Das Projekt wird begleitend evaluiert: Mithilfe von Befragungen und Usability-Tests sollen die Akzeptanz des Wikis und das Nutzerverhalten überprüft werden. Darüber hinaus wird die nutzerorientierte Taxonomie (Folksonomy) mit Thesauri im Bildungswesen verglichen. Eine ausführlichere Darstellung des Projekts sowie eine Übersicht über alle Projekte der Bildungsinformation ist zu finden unter: www.dipf.de/bildungsinformation/projekte.htm.
