    Abstract
    Themenentdeckung und -verfolgung (topic detection and tracking; TDT) fasst unterschiedliche Dokumente zu einem Thema zusammen und bietet dem Nutzer zunächst das Thema und erst in einem zweiten Schritt die einzelnen Dokumente zur Anzeige an. TDT ist nützlich bei Nachrichten sowie bei Blog-Einträgen. Ein bekanntes Beispiel ist Google News. Der Artikel bespricht den Forschungsstand zu TDT und diskutiert den Einsatz von TDT bei News-Informationsdiensten wie z.B. Factiva oder LexisNexis. Dort ist TDT zweifach wichtig: Erstens ist es (analog zu Google News) bei Profildiensten einsetzbar, zweitens ist es möglich, Dokumente zum gleichen Thema in einen Ordner zu klassieren, um bei einer retrospektiven Recherche die Treffermenge geordnet nach unterschiedlichen Themen anzubieten (und dies ohne Nutzung einer Dokumentationssprache).

    Abstract
    To better understand how individuals and groups derive satisfaction from information, it is important to identify the information source preferences they apply in information seeking and decision making. Four informal propositions drove the structure and underlying logic of this study, forming a preliminary outline of a theory of information source preference profiles and their influence an information satisfaction. This study employed Social Judgment Analysis (SJA) to identify the information judgment preferences held by professional groups for six selected information sources: word of mouth, expert oral advice, Internet, print news, nonfiction books, and radio/television news. The research was designed as an hypotheses-generating exploratory study employing a purposive sample (n = 90) and generated four empirically supported, testable hypotheses about user satisfaction with information sources. The SJA judgment functions revealed the influences of volume and polarity (i.e., positive versus negative information) an information satisfaction. By advancing the understanding of how information source preferences can be identified empirically and their influence an information satisfaction, this research reflects a first, small step toward understanding "satisficing." Satisficing behaviors result in early termination of information search processes when individuals, facing incomplete information, are sufficiently satisfied to assume risks and execute decisions.

    Abstract
    Informal groups of professional workers are forming online communities to create and share information with each other. This paper offers an analysis of an online community of news reporters. Through participant observation in the group electronic discussion, and analysis of archival copies of the group conversation, the authors explore the ways in which this group requests and offers assistance to each other. The types of information created are examined and the temporal characteristics of the group are explored. The analysis revealed a vibrant online community of professionals who use the online communication medium to compliment professional face to face meetings and other forms of communication such as newsletters and journals.

    Abstract
    Pettigrew, Durrance, and Unruh report on data collected by survey, interview, field observation and focus groups concerning three communities recognized for community information networks in which the local public library played a leading role. The survey was posted for 73 days on the website of each network and yielded 197 responses providing insights on how the public uses CI systems, barriers encountered, and resulting benefits to users and communities. Responding users were diverse demographically, and sought a wide variety of information types. The information types were broader than previous CI studies with a strong emphasis on employment, volunteerism, social services, local history and genealogy, sale, exchange and donation of goods, news, and technical information. Barriers identified were technological, economic, geographic, search skill related, cognitive, and psychological, as well as a large class of information related barriers concerning the quality of the information provided, its accessibility, and security. Users are identified who browse the CI system with particular interest in discovering material of potential value to others. The systems are valued and used by the adult population and seem to strengthen existing communities while stimulating the formation of information communities.

    Abstract
    This article focuses an analysing students' information needs in terms of conceptual understanding of the topic they propose to study and its consequences for the search process and outcome. The research subjects were 22 undergraduates of psychology attending a seminar for preparing a research proposal for a small empirical study. They were asked to make searches in the PsycINFO database for their task in the beginning and end of the seminar. A pre- and postsearch interview was conducted in both sessions. The students were asked to think aloud in the sessions. This was recorded, as were the transaction logs. The results show that during the preparation of research proposals different features of the students' conceptual structure were connected to the search success. Students' ability to cover their conceptual construct by query terms was the major feature affecting search success during the whole process. In the beginning also the number of concepts and the proportion of subconcepts in the construct contributed indirectly via search tactics to retrieving partly useful references. Students' ability to extract new query terms from retrieved items improved search results.

    Abstract
    Wie müssen wir virtuelle Rundgänge und Online-Tutorials gestalten, damit sie ihre Zielgruppe auch wirklich erreichen? Worauf müssen wir bei einer guten Präsentation unseres OPACs achten? Was machen wir mit großen Schülergruppen? Diesen Fragen stellten sich insgesamt 22 Bibliothekarinnen und Bibliothekare in Münster und Köln während zweier Fortbildungsveranstaltungen des HBZ im Juni 2003. Ziel der jeweils zweitägigen Workshops, die in Zusammenarbeit mit der Adhoc-Arbeitsgruppe "Informationskompetenz" der AG der Universitätsbibliotheken im VBNW konzipiert wurden, waren Konzepte und erste Schritte zur Umsetzung von elektronischen Angeboten zur Vermittlung von Bibliotheksbzw. Informationskompetenz. Dem voraus ging die konstruktive Bewertung von bereits existierenden Materialien, die zum einen von den Teilnehmern aus ihren Bibliotheken mitgebracht wurden, zum anderen über Bibliotheks-Homepages abrufbar waren. Die Teilnehmer, die in ihren Bibliotheken bereits Benutzerschulungen konzipieren und durchführen, beschäftigten sich dabei in Gruppen u.a. mit den Themen - Virtuelle Rundgänge, - Online-Tutorials - Bibliothekseinführungen für Schüler und Erstsemester - Präsentationen von Online-Katalog und Methoden zur Literatursuche. Im Folgenden werden einige wesentliche und manchmal durchaus kontrovers diskutierte Ergebnisse und Thesen wiedergegeben, die sich aus der Arbeit der Teilnehmer ergeben haben. Sie erheben keinen Anspruch auf Ausgewogenheit oder Vollständigkeit, können aber als Anregungen und Diskussionsgrundlage für zukünftige Projekte dienen.
