    Abstract
    Die Notwendigkeit des professionellen Einsatzes von empirischen Methoden als Grundvoraussetzung für den Entwurf und die Gestaltung von Informationsdiensten, Informationsprodukten und Informationssystemen ist seit den frühen sechzigerfahren in der Informationsarbeit erkannt worden. Anfänglich wurde - ausgedrückt durch die Bezeichnung "Benutzerforschung" oder "fachliche Rezipientenforschung" -versucht, den Informationsbedarfvon unterschiedlichen Benutzergruppen (im Rahmen einer Typologie der Benutzer von Informationssystemen) zu messen und aufgrund dieser Daten zu Einschätzungen von Art, Menge, Umfang und Tiefe von Informationsbedürfnissen zu gelangen. "Benutzerforschung sollte den Lebensweg von Informationsprodukten beziehungsweise Informationsdiensten begleiten. Sie kann erste Anregungen geben, sie liefert Entscheidungshilfen im Planungsstadium und kontrolliert dann, ob, wo und wie sich der geplante Erfolg tatsächlich eingestellt hat." In den siebziger und achtziger Jahren traten dann Fragestellungen in den Vordergrund, die den allgemeinen Nutzen der Information und besonders der Strukturen und Prozesse der Informationsvermittlung empirisch zu beschreiben versuchten. Darüber hinaus wurden mit dem in den siebziger Jahren dann vollzogenen Einsatz der Informationsund Kommunikationstechnologien in den Bibliotheken und Informationsstellen Fragestellungen wichtig, die unter dem Begriff "Kommunikationsanalysen" etwa die Ansätze der Informationsbedarfsmessung mit der empirischen Analyse des Einsatzes von Informations- und Kommunikationstechnologien verbanden. Ein weiteres Einsatzfeld empirischer Untersuchungen ergab sich aus dem langsamen Entstehen eines Marktes für elektronische Informationsprodukte, wodurch sowohl empirische Marktforschungsstrategien als auch empirische Marketingansätze in die Informationsarbeit hineingetragen wurden. Schließlich traten Untersuchungen der Benutzerfreundlichkeit von Informationssystemen und ihrer Bedienbarkeit sowie dann die allgemeinen Kriterien der Softwareergonomie hinzu. Ferner werden seit den 90er Jahren durch die Nutzung des Internets als Angebotsmedium Aspekte der Kundenorientierung und Fragen der empirischen Nutzungsforschung und der Bedienungsfreundlichkeit (Usability) zunehmend wichtiger. Dementsprechend haben sich auch die Begrifflichkeiten für die Benutzerforschung in Bibliotheken gewandelt: Von Benutzung, Benutzerbedürfnisse, Benutzerforschung, Benutzerfreundlichkeit über Benutzerorientierung, Benutzerzufriedenheit, Benchmarking, Qualitätsmanagement, Bibliotheksmarketing hin zu Kundenorientierung, Kundenzufriedenheit, Service. Hinsichtlich der Internet-Angebote kamen dann Aspekte des Benutzerverhaltens und der Bedienungsfreundlichkeit der Software bzw der Benutzerschnittstellen hinzu. Allen Konzepten ist gemeinsam, dass sie im weitesten Sinne den Prozess der gesellschaftlichen Informationsvermittlung auf einer übergreifenden Ebene verstehbar machen: Aus der Sicht des Nutzers von Information, aus der Sicht manifester und latenter Informationsbedürfnisse, aus der Sicht technisch unterstützter fachlicher Informationsund Kommunikationsprozesse der Information und Dokumentation oder aus der Sicht technischer und ästhetischer Gestaltung. Diese hier grob unterschiedenen Ansätze werden nun unter dem Begriff Informationsanalyse zusammengefasst.

    Abstract
    This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web

    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
    Several previous studies have measured differences in the information search success of novices and experts. However, the definitions of novices and experts have varied greatly between the studies, and so have the measures used for search success. Instead of dividing the searchers into different groups based on their expertise, we chose to model search success with task completion speed, TCS. Towards this goal, 22 participants performed three fact-finding tasks and two broader tasks in an observational user study. In our model, there were two variables related to the Web experience of the participants. Other variables included, for example, the speed of query iteration, the length of the queries, the proportion of precise queries, and the speed of evaluating result documents. Our results showed that the variables related to Web experience had expected effects on TCS. The increase in the years of Web use was related to improvement in TCS in the broader tasks, whereas the less frequent Web use was related to a decrease in TCS in the fact-finding tasks. Other variables having significant effects on TCS in either of the task types were the speed of composing queries, the average number of query terms per query, the proportion of precise queries, and the participants' own evaluation of their search skills. In addition to the statistical models, we present several qualitative findings of the participants' search strategies. These results give valuable insight into the successful strategies in Web search beyond the previous knowledge of the expert-novice differences.

    "Als Generation @ werden Kinder und Jugendliche in der Öffentlichkeit bereits gefeiert, insbesondere Marketing und Werbung schwärmen vom geschickten, unermüdlichen Surfen im WWW, von kinderleichter Handhabung des Equipments, spielerischem Edutainment und spannenden Verlockungen des digitalen Lernens, und zwar schon für die Kleinsten ab dem Kindergartenalter. Mehrheit noch offline Imposant sind auch die quantitativen Daten zur Haushaltsausstattung und PC- beziehungsweise Internetnutzung, vor allem ihre Wachstumsraten, die die Studie von Christine Feil und Co-Autoren referiert und miteinander abgleicht. Susanne Richter (S. 18) hingegen weiß nichts von ihrer Existenz, zumal Angaben aus kommerziellen Kontexten meist zu Obertreibungen neigen. Seriöser sind die Angaben des so genannten Medienpädagogischen Forschungsverbundes Südwest, der seit 1999 die Studie »Kinder und Medien« (»KIM-Studie«) durchführt, 2003 zum vierten Mal. Danach hatten 57 Prozent der bundesdeutschen Haushalte mit 6- bis 13-jährigen Kinder Internet zu Hause (Feil S. 15),42 Prozent der 6-bis 13-Jährigen besuchen hin und wieder das Internet, nur etwa gut zwölf Prozent sind täglich oder mehrmals in der Woche nach Schätzungen durchschnittlich zwischen einer halben und einer Stunde im Netz, werden aber von kommerzieller Seite bereits als »Heavy User« apostrophiert (Feil S. 18). Etwa bei zehn, elf Jahren lag 2003/2004 das Einstiegsalter für das Internet, bei Mädchen und bei Kindern aus niedrigeren Einkommens- und Sozialschichten etwas später. Offenbar haben die inzwischen - auch schon im Primarbereich - gut ausgestatten Schulen noch »kaum kompensatorische Wirkung im Sinne gleicher Zugangschancen für alle Kinder« entfaltet, »sondern allenfalls den Anteil der Kinder mit Sowohl-als-auch-Zugang« erhöht (Feil S. 21). So zeichnen sich tendenziell zwar jeweils steigende Beteiligungen ab, aber »die Mehrheit der Kinder« ist noch »offline«. Und der Zugang der Kinder zum Netz allein »gibt weder Aufschluss über ihre Nutzungskompetenzen noch über die Bedeutung der Kommunikationsund Informationsfunktion des Internets für Kinder« (Feil S. 30), so die sicherlich stimmige Ausgangsthese.
