    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
    Hypothesizing that workplace significantly affects information-seeking patterns, this study compared accessibility and use of information sources among 233 Israeli computer scientists and software engineers, employed in industry and academy, using a mail questionnaire, which yielded a usable reply rate of 33%. The two groups were found to differ significantly in age, education, seniority, and type of research they performed (basic vs. applied). Printed textbooks, professional journals, and oral discussions with colleagues or experts in the organization were common to both groups, topping almost all lists of accessibility and use. For most information sources, however, the two groups differed significantly and consistently. Printed professional journals as weIl as printed and electronic conference or meeting papers were consistently more accessible and more often used by the academy group, while the industry group reported greater access to and more frequent use of electronic textbooks and trade or promotional literature. In regard to handbooks and standards, in-house technical reports (printed), government technical reports (Internet), librarians and technical specialists (Internet), and oral discussions with supervisors, no significant differences in accessibility were found, but their use by the industry group was much higher. In both groups, accessibility was only partly related to use, and more so among the academy than the industry group.

    Abstract
    Unsere Medienwelt ist vom Nebeneinander verschiedener Ausgabeformen derselben Inhalte geprägt. Es herrscht jedoch Mangel an Untersuchungen, welche die "usability" von Printmedien mit der von Online-Medien direkt vergleichen. Im Rahmen eines Projektseminars am Institut fürBibliothekswissenschaft der Humboldt- Universität Berlin wurde die Usability von gedruckten und von Online-Informationsmitteln anhand heuristischer Kriterien verglichen. Als Benutzungsaspekte bündelndes und messbares Kriterium wurde der Zeitbedarf zur Beantwortung einfacher Testaufgaben ermittelt, die sowohl anhand der Print- als auch anhand der Online-Version je eines Versandhauskatalogs und eines Vorlesungsverzeichnisses zu beantworten waren. Die Prognosen sowie die Ergebnisse dreier Gruppen (Bibliothekswissenschaft-Studenten, Informatik-Studenten und Laien) wurden verglichen. Der Zeitbedarf für die Nutzung der Printmedien wurde von den Bibliothekswissenschaft- und Informatik-Studenten zu hoch prognostiziert, für Online-Medien zu niedrig. Der tatsächliche Zeitbedarf bewegte sich in ähnlicher Größenordnung bei beiden Versionen des Vorlesungsverzeichnisses. Bei der Nutzung des Versandhauskatalogs hingegen war der Zeitbedarf online doppelt so hoch wie beim Printmedium. Zusätzlich war bei Nutzung der Online-Version die Hälfte der Antworten falsch. Der Grad an subjektiver Unsicherheit über die Richtigkeit der Antworten wurde, damit übereinstimmend, bei der Online-Version deutlich höher eingeschätzt als beim Printmedium. Die Testergebnisse derdrei Gruppen unterschieden sich beim Versandhauskatalog nur wenig. Die Ergebnisse werden als Hinweis auf schlechten Entwicklungsstand der Usability von Online-Medien gedeutet. Die Usabilityvon konventionellen Medien scheint von "computernahen" Nutzern unterschätzt zu werden. Bei der Nutzung von Online-Medien wird in derLiteratur oft hohe subjektive Unsicherheit über die Angemessenheit oder Richtigkeit der Suchresultate berichtet, die hier bestätigt wird und zugleich mit einem hohen Anteil objektiv falscher Antworten korrespondiert. Es wird dafür plädiert in die Usability-Forschung konventionelle Medien einzubeziehen und stärker interdisziplinär vorzugehen.

    Abstract
    Die Arbeit untersucht die Usability von Online-Wörterbüchern und elektronischen Sprachportalen und soll eine Brücke zwischen der Usability von Websites hinsichtlich softwareergonomischer Normen und Konventionen und Wörterbüchern in elektronischer Form schlagen. Die einzige Usability-Methode, mit der es möglich ist, konkrete und empirisch belegte Aussagen darüber zu treffen, wie potentielle Nutzer ein Online-Wörterbuch verwenden und welche Probleme dabei festgestellt werden, ist ein Usability- Test mit realen Benutzern. Als Untersuchungsgegenstand dient das Online-Wortschatz-Informationssystem Deutsch (Owid), die Base lexicale du français (BLF) und das elektronische Lernerwörterbuch Deutsch-Italienisch (Eldit). Die Arbeit setzt sich aus vier verschiedenen empirischen Studien zusammen. Da ein Usability-Test immer nur einen Ausschnitt an Funktionalitäten aus einem gesamten System widerspiegeln kann, wurden mithilfe einer empirischen Fragebogen-Studie zunächst die für den Benutzer wichtigsten und am meisten verwendeten Funktionen eines Online-Wörterbuchs identifiziert und als Grundlage für den Test gewählt. Eine anschließende heuristische Evaluation trug potentielle Usability-Probleme der drei Online- Wörterbücher zusammen und stellte die Grundlage für die Thesenstellung des Usability-Tests dar. Der Test setzte sich aus zwei empirischen Teilen zusammen: Einem Aufgabenteil, den die Testperson für jedes der drei Online-Wörterbüchern einzeln bearbeiten und dabei die Testmethode des lauten Denkens anwenden musste und einem Post-Test- Fragebogen, der direkt nach dem Bearbeiten des jeweiligen Aufgabenkatalogs ausgefüllt wurde. Der gesamte Test wurde mit Morae, einer Software u. a. für Software- und Website- Usability-Tests, durchgeführt und ausgewertet.

    Abstract
    Account of a limited experimental study at the Bibliothèque Publique d'Informations (BPI), the Paris multimedia public library, to establish a methodology for investigating user interactions with new technology. A wide range of materials are available at the BPI, including CD-ROMs and the Internet. Preliminary observations indicate that users do not follow the pattern dictated by the machine, but take approaches based on their own experience and skills. Setbacks are generally interpreted as defects in the software, not personla failure to master the system. Large scale qualitative abservation, using research methods from the social sciences, would establish a knowledge base for developing user skills to exploit multimedia resources more fully

    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
    Eye movement data can provide an in-depth view of human reasoning and the decision-making process, and modern information retrieval (IR) research can benefit from the analysis of this type of data. The aim of this research was to examine the relationship between relevance criteria use and visual behavior in the context of predictive relevance judgments. To address this objective, a multimethod research design was employed that involved observation of participants' eye movements, talk-aloud protocols, and postsearch interviews. Specifically, the results reported in this article came from the analysis of 281 predictive relevance judgments made by 24 participants using the Google search engine. We present a novel stepwise methodological framework for the analysis of relevance judgments and eye movements on the Web and show new patterns of relevance criteria use during predictive relevance judgment. For example, the findings showed an effect of ranking order and surrogate components (Title, Summary, and URL) on the use of relevance criteria. Also, differences were observed in the cognitive effort spent between very relevant and not relevant judgments. We conclude with the implications of this study for IR research.

    Abstract
    The study reported here investigated the query expansion behavior of end-users interacting with a thesaurus-enhanced search system on the Web. Two groups, namely academic staff and postgraduate students, were recruited into this study. Data were collected from 90 searches performed by 30 users using the OVID interface to the CAB abstracts database. Data-gathering techniques included questionnaires, screen capturing software, and interviews. The results presented here relate to issues of search-topic and search-term characteristics, number and types of expanded queries, usefulness of thesaurus terms, and behavioral differences between academic staff and postgraduate students in their interaction. The key conclusions drawn were that (a) academic staff chose more narrow and synonymous terms than did postgraduate students, who generally selected broader and related terms; (b) topic complexity affected users' interaction with the thesaurus in that complex topics required more query expansion and search term selection; (c) users' prior topic-search experience appeared to have a significant effect on their selection and evaluation of thesaurus terms; (d) in 50% of the searches where additional terms were suggested from the thesaurus, users stated that they had not been aware of the terms at the beginning of the search; this observation was particularly noticeable in the case of postgraduate students.

    Abstract
    Discusses the necessity of providing new methods of research into user information retrieval behaviour. Notes that the user using the catalogue via the Internet and communicating exclusively with the computer system, disappears from the librarian's direct view. Implementing adequate software facilities in some sense broadens research prospects and improves its quality. Describes research carried out at the Jagiellonian Library, Poland, into the extent of use of OPAC retrieval facilities, throught the application of software that records all information retrieval commands

    Abstract
    ADEPT is a 5-year project whose goals are to develop, deploy, and evaluate inquiry learning capabilities for the Alexandria Digital Library, an extant digital library of primary sources in geography. We interviewed nine geography faculty members who teach undergraduate courses about their information seeking for research and teaching and their use of information resources in teaching. These data were supplemented by interviews with four faculty members from another ADEPT study about the nature of knowledge in geography. Among our key findings are that geography faculty are more likely to encounter useful teaching resources while seeking research resources than vice versa, although the influence goes in both directions. Their greatest information needs are for research data, maps, and images. They desire better searching by concept or theme, in addition to searching by location and place name. They make extensive use of their own research resources in their teaching. Among the implications for functionality and architecture of geographic digital libraries for educational use are that personal digital libraries are essential, because individual faculty members have personalized approaches to selecting, collecting, and organizing teaching resources. Digital library services for research and teaching should include the ability to import content from common office software and to store content in standard formats that can be exported to other applications. Digital library services can facilitate sharing among faculty but cannot overcome barriers such as intellectual property rights, access to proprietary research data, or the desire of individuals to maintain control over their own resources. Faculty use of primary and secondary resources needs to be better understood if we are to design successful digital libraries for research and teaching.
