    Abstract
    Bilal, in this third part of her Yahooligans! study looks at children's performance with self-generated search tasks, as compared to previously assigned search tasks looking for differences in success, cognitive behavior, physical behavior, and task preference. Lotus ScreenCam was used to record interactions and post search interviews to record impressions. The subjects, the same 22 seventh grade children in the previous studies, generated topics of interest that were mediated with the researcher into more specific topics where necessary. Fifteen usable sessions form the basis of the study. Eleven children were successful in finding information, a rate of 73% compared to 69% in assigned research questions, and 50% in assigned fact-finding questions. Eighty-seven percent began using one or two keyword searches. Spelling was a problem. Successful children made fewer keyword searches and the number of search moves averaged 5.5 as compared to 2.4 on the research oriented task and 3.49 on the factual. Backtracking and looping were common. The self-generated task was preferred by 47% of the subjects.

    Abstract
    Nach Einführungen zu Jugend und Internet, Medienkompetenz und Lernen durch Medien, wird im praktischen Teil eine schriftliche Umfrage unter 90 Schülern eines Gymnasiums und einer Gesamtschule über deren Internetnutzung für schulische Zwecke analysiert. Suchpraxis, Einbindung des Internets in den schulischen Alltag, Unterschiede bei Geschlechtern und Schulformen werden besonders untersucht. Die Auswertung ergibt selbstbewußte Grundeinstellung der Schüler zum Internet, eher privat als schulisch genutzt, geschätzt wegen Schnelligkeit, Informationsmenge und Spaßfaktor bei Fixierung auf die Suchmaschine Google. Die Schüler geben sich meistens mit den gefundenen Ergebnissen zufrieden, stellen deren Qualität nicht weiter in Frage.

    Abstract
    Meho and Tibbo show that the Ellis model of information seeking applies to a web environment by way of a replication of his study in this case using behavior of social science faculty studying stateless nations, a group diverse in skills, origins, and research specialities. Data were collected by way of e-mail interviews. Material on stateless nations was limited to papers in English on social science topics published between 1998 and 2000. Of these 251 had 212 unique authors identified as academic scholars and had sufficient information to provide e-mail addresses. Of the 139 whose addresses were located, 9 who were physically close were reserved for face to face interviews, and of the remainder 60 agreed to participate and responded to the 25 open ended question interview. Follow up questions generated a 75% response. Of the possible face to face interviews five agreed to participate and provided 26 thousand words as opposed to 69 thousand by the 45 e-mail participants. The activities of the Ellis model are confirmed but four additional activities are also identified. These are accessing, i.e. finding the material identified in indirect sources of information; networking, or the maintaining of close contacts with a wide range of colleagues and other human sources; verifying, i.e. checking the accuracy of new information; and information managing, the filing and organizing of collected information. All activities are grouped into four stages searching, accessing, processing, and ending.

    Abstract
    A survey of 4,032 youth in grades 5 through 12 was conducted to determine the impact youth's use of the Internet was having on their use of the public library. Results indicated that 100% of the youth had access to the Internet from one or more locations, and that although one quarter of the youth accessed the Internet at the public library, the public library was the least frequently used source of Internet access. For youth without Internet access at home, the public library was also the least used alternate source of access. Approximately 69% of the youth reported that they had visited a public library during the school year. Having Internet access at home did not affect whether or not youth visited the library however, Internet access at home appears to have affected the frequency with which youth visit the library. Youth without Internet access at home visited the library more frequently, whereas youth with Internet access at home visited the library less frequently. Use of the Internet also appeared to have diminished youth's need to use the public library as a source of personal information however, use of the Internet appeared not to have affected their use of the public library for school work or for recreation. Among youth, use of both the Internet and the public library appear to be complementary activities.

    Abstract
    Der Artikel betrachtet anhand einer Studie zum Benutzerverhalten bei der Online-Katalogrecherche den gegenwärtigen Stellenwert und das zukünftige Potential der Web-OPACs. Dabei werden zunächst die Ergebnisse einer quantitativen Logfile-Analyse sowie qualitativer Benutzertests erörtert, bevor aktuelle Entwicklungen der Webtechnologie, die unter den Schlagworten Web 2.0 und Web 3.0 propagiert werden, im Zusammenhang mit der Online-Recherche und der Entwicklung neuartiger Suchverfahren kurz diskutiert werden.

    Abstract
    Gegenstand der empirischen Forschungsarbeit sind dargestellte wie empfundene Gefühle bei Videos. Sind Nutzer in der Lage, solche Gefühle derart konsistent zu erschließen, dass man deren Angaben für ein emotionales Videoretrieval gebrauchen kann? Wir arbeiten mit einem kontrollierten Vokabular für neun tionen (Liebe, Freude, Spaß, Überraschung, Sehnsucht, Trauer, Ärger, Ekel und Angst), einem Schieberegler zur Einstellung der jeweiligen Intensität des Gefühls und mit dem Ansatz der broad Folksonomy, lassen also unterschiedliche Nutzer die Videos taggen. Versuchspersonen bekamen insgesamt 20 Videos (bearbeitete Filme aus YouTube) vorgelegt, deren Emotionen sie indexieren sollten. Wir erhielten Angaben von 776 Probanden und entsprechend 279.360 Schiebereglereinstellungen. Die Konsistenz der Nutzervoten ist sehr hoch; die Tags führen zu stabilen Verteilungen der Emotionen für die einzelnen Videos. Die endgültige Form der Verteilungen wird schon bei relativ wenigen Nutzern (unter 100) erreicht. Es ist möglich, im Sinne der Power Tags die jeweils für ein Dokument zentralen Gefühle (soweit überhaupt vorhanden) zu separieren und für das emotionale Information Retrieval (EmIR) aufzubereiten.

    Abstract
    Anfang 1994 eröffnete die SWB-Verbundzentrale einen TELNET-Recherchezugang für Endnutzer zur SWB-Datenbank. Damit bot sich zugleich die Möglichkeit, ein Feedback über die Recherchebedürfnisse und -strategien von Endnutzern zu erhalten: zum einen durch eine statistische Erfassung der Nutzerrecherchen über einen Zeitraum von 7 Monaten, zum anderen durch auswertung von E-Mail- Nachrichten der Endnutzer mit Stellungnahmen zur angebotenen Rechercheschnittstelle. Die Ergebnisse der Untersuchung werden unter dem Gesichtspunkt vorgestellt, welche Vorgaben sich aus ihnen für die Gestaltung einer geplanten WWW-Recherche-Oberfläche für die SWB-Verbunddatenbank ableiten lassen

    Abstract
    Usability evaluations and observations of users shopping at Amazon.com (http://www.amazon.com) revealed some interesting user behaviors. The mixed behavior patterns were leveraged to create an interface for an e-commerce product. The author describes some design practices for providing a scoped search interface for an e-commerce site.
