    Abstract
    Das gezielte Suchen im Internet findet in erster Linie mit Hilfe der Suchmaschinen statt. Daneben gibt es aber bereits eine Fülle von strukturierten Informationsangeboten, aufbereiteten Listen und Sammelstellen, die als Clearinghouse, Subject Gateway, Subject Tree oder Resource Pages bezeichnet werden. Solche intellektuell erstellten Übersichten geben in der Regel bereits Hinweise zu Inhalt und fachlichem Niveau der Quelle. Da die Art und Weise der Aufbereitung bei den Sammelstellen sehr unterschiedlich funktioniert, ist die Kenntnis ihrer Erschließungskriterien für ein erfolgreiches Retrieval unverzichtbar

    Abstract
    Die enorme Menge an im Internet verfügbaren Daten und die gleichzeitig fehlende Möglichkeit einer zentralen Koordination der Inhalte haben dazu geführt, daß zahlreiche Dienste für die Suche und den Nachweis von Internetressourcen (im folgenden Suchdienste genannt) entstanden sind. Gegenwärtig existieren Hunderte von Suchdiensten mit großen Unterschieden in der Arbeitsweise, dem Umfang und den angebotenen Funktionalitäten. Die Zahl der großen, globalen Suchdienste ist zwar in den letzten Jahren relativ konstant geblieben, doch sind gerade diese Dienste durch ständige Veränderungen gekennzeichnet. Sie bieten immer mehr Retrievalfunktionen an und erweitern den Umfang an Zusatzangeboten, die über die reine Suche in einer Datenbank hinausgehen, ständig. Dies führt dazu, daß Informationssuchende Schwierigkeiten bei der Auswahl der für ihre Fragestellung passenden Dienste haben. Besonders gelegentlichen Nutzern von Internet-Suchdiensten fällt es schwer, sich einen Überblick zu verschaffen und Dienste differenziert zu einzusetzen

    Abstract
    Kompetenter Überblick über die verschiedenen Werkzeuge, die für die Informationssuche im Netz zur Verfügung stehen. Er beschränkt sich nicht nur auf die übliche Beschreibung von Yahoo, Altavista & Co., sondern geht auf alle wichtigen Informationsquellen im Internet und den Onlinediensten ein. So beschäftigt sich der Autor auch mit der Recherche im Usenet oder in Mailinglisten und erläutert die unterschiedlichen Newsquellen in Compuserve, AOL und T-Online

    Evaluates the performance of 8 major Internet search engines in answering 21 real reference questions and 5 made up subject questions. Reports on the retrieval and relevancy ranking abilities of the search engines. Concludes that the search engines did not produce good results for the reference questions unlike for the subject questions. The best engines are identified by type of questions, with Infoseek best for the subject questions, and OpenText best for refrence questions

    Abstract
    Reports on research into the information-seeking habits of primary schoolchildren conducted under operational conditions. Three workstations with Internet access were installed in a grade-six classroom in suburban Montreal. After a short introductory training session for the entire group followed by short individual sessions for each student, 53 students, working in small groups, used these workstations over a six-week period to seek information on the Web of relevance to a class project assigned by their teacher. The project dealt with the Winter Olympic Games (recently completed at that time). The student objective was to locate relevant information for a poster and an oral presentation on one of the sports represented at the Games. All screen activity was directly captured on videotape and group conversations at the workstation were audiotaped. Demographic and computer literacy information was gathered in a questionnaire. This paper presents a map of the information-seeking landscape based upon an analysis of the descriptive statistics gathered from the Web searches. It reveals that the novice users favored browsing over analytic search strategies, although they did show some sophistication in the construction of the latter. Online help was ignored. The children demonstrated a very high level of interactivity with the interface at the expense of thinking, planning and evaluating. This is a preliminary analysis of data which will subsequently be expanded by the inclusion of qualitative data

    Abstract
    Das Internet entwickelt sich zunehmend zu einem Medium, das prinzipiell jedem Informationen aus allen Bereichen zugänglich macht, egal, ob es sich um Themen wie Recycling, Fussballbundesliga, Geldanlage oder Urlaubsreisen handelt. Durch die Fülle der zu durchsuchenden Daten übersteigt der Zeitaufwand für die Prüfung und Auswertung der Daten jedoch häufig den eigentlichen Nutzen der gesuchten Information. Genau hier setzt dieses Buch an, indem es systematisch die wichtigsten Hilfsmittel für die Informationssuche im Internet auf ihre Leistungsfähigkeit und Eignung bei der Suche beschreibt und bewertet. Außerdem werden Strategien zur richtigen Kombination von Suchhilfsmitteln vermittelt, Tips zur schnellen Beurteilung der gefundenen Informationen gegeben und Möglichkeiten beschrieben, wie man als Informationsanbieter im Internet gefunden werden kann

    Abstract
    The paper presents findings from a study of how knowledge workers use the Web to seek external information as part of their daily work. Thirty four users from seven companies took part in the study. Participants were mainly IT specialists, managers, and research/marketing/consulting staff working in organizations that included a large utility company, a major bank, and a consulting firm. Participants answered a detailed questionnaire and were interviewed individually in order to understand their information needs and information seeking preferences. A custom-developed WebTracker Software application was installed an each of their workplace PCs, and participants' Web-use activities were then recorded continuously during two-week periods. The WebTracker recorded how participants used the browser to seek information an the Web: it logged menu choices, button bar selections, and keystroke actions, allowing browsing and searching sequences to be reconstructed. In a second round of personal Interviews, participants recalled critical incidents of using information from the Web.Data from the two Interviews and the WebTracker logs constituted the database for analysis. Sixty one significant episodes of Information seeking were identified. A model was developed to describe the common repertoires of Information seeking that were observed. On one axis of the model, episodes were plotted according to the four scanning modes identified by Aguilar (1967), Weick and Daft (1983): undirected viewing, conditioned viewing, informal search, and formal search. Each mode is characterized by its own Information needs and Information seeking strategies. On the other axis of the model, episodes were plotted according to the occurence of one or more of the six categories of information seeking behaviors identified by Ellis (1989, 1990): starting, chaining, browsing, differentiating, monitoring, and extracting. The study suggests that a behavioral framework that relates motivations (Aguilar) and moves (Ellis) may be helpful in analysing patterns of Web-based Information seeking

    Abstract
    Dieses Buch bietet einen sehr guten Überblick, wie man sich Informationen schnell und effizient verschaffen kann. Neben Suchmaschinen werden auch Mailing-Listen und Newsgroups (Diskussionforen) vorgestellt. Es wird anschaulich beschrieben, wie sie gegliedert sind und wie man daran teilnehmen kann. Rund die Hälfte des Buches beschäftigt sich mit Spezialrecherchen, wie etwa die Suche nach Software, Personen oder Jobs. Im Kapitel 'Quellen für Aus- und Fortbildung' findet man neben der 'Free Internet Encyclopdedia' und den 'Online Dictionaries' viele weitere nützliche Adressen. Obwohl sich das Buch primär an Profis richtet, ist es auch für Einsteiger geeignet. Die Recherchestrategien werden allgemein verständlich erklärt

    Abstract
    Selten wurde ein Dienst so stark diskutiert wie 'RealNames', da sowohl seine Suchwörter als auch die darauf aufsetzenden Links auf Homepages verkauft werden. Machen wir uns doch nichts vor: Das WWW ist ein kommerzielles Unternehmen, die Dienstleistungen müssen finanziert werden. Und warum soll nicht ein Privatunternehmen mit Inhaltserschließung Gewinne erzielen? RealNames mit seinem 'Internet Keyword System' ist eine interessante Idee, das Retrieval nach Homepages zielgenau durchzuführen. Was bringt RealNames den Nutzern? Wann sollte jemand, der Sites im WWW unterhält, Suchwörter und Links bei RealNames abonnieren (und was kostet das)? Im Oktober 1999 haben wir RealNames genauer angeschaut. Analysiert wurde das gezielte Retrieval nach Homepages bei AltaVista, Fireball und bei RealNames.com

    Abstract
    Despite development of the WWW searchers still experience difficulties following links between sites and cannot be sure that a site contains the required information. 3 software programs developed to guide users through the maze of hyperlinks are: Dynamic diagrams, the Hyperbolic tree, and the Brain. in contrast to the other programs which operate on webservers and display hyperlinks in diagrammatic form the Brain is installed on individual PCs and can be customised to meet users' requirements
