    Abstract
    An 2 biowissenschaftlichen Einrichtungen der Grundlagenforschung, dem Max-Delbrück-Centrum für Molekulare Medizin, Berlin-Buch und dem Leibniz-Institut für Neurobiologie, Magdeburg, wurden 1997 bzw. 1998 Nutzerbefragungen durchgeführt. Obwohl die untersuchten Gruppen beträchtliche Altersunterschiede aufwiesen, ergeben sich einheitliche Trends: für etwa 2/3 der Wissenschaftler ist gegenwärtig die Nutzung von Printmedien und elektronischen Informationsofferten gleichwertig, während etwa 15% der Befragten letzteren den Vorzug geben. Bei der Datenbanknutzung ist festzustellen, daß MEDLINE die überragende Position sowohl bei der CD-ROM als auch Online im Internet einnimmt

    Abstract
    Die Deutsche Forschungsgemeinschaft fördert in 23 Universitätsbibliotheken (Sondersammelgebieten), 47 Spezialbibliotheken und 3 zentralen Fachbibliotheken ein System der überregionalen Literatur- und Informationsversorgung. Dieses System kooperativer umfassender Sammlung weltweit vorhandener wissenschaftlicher Literatur sollte erstmals aus der Nutzerperspektive evaluiert werden. Es sollten Form und Umfang der tatsächlichen wie der potentiellen Nutzung sowie jetzige und zukünftige Bedarfe ermittelt werden, und zwar beispielhaft in den Fächern Anglistik, Betriebswirtschaft, Biologie, Geschichte und Maschinenbau. Das Projekt wurde 2002/2003 von der Universitäts- und Landesbibliothek Münster zusammen mit infas-Institut für angewandte Sozialwissenschaft GmbH durchgeführt. Diese Veröffentlichung zeigt den ersten Teil der Ergebnisse, die das Informationsverhalten von Wissenschaftlern und Wissenschaftlerinnen in den fünf Fächern betreffen.

    Abstract
    Previous empirical studies of searcher behaviour have drawn attention to a wide variety of factors that affect performance; for instance, the display of retrieved results can alter search strategies (Allen 1991, 1994), the information need type influences search behaviour, (Elkerton et al 1984, Marchionini 1995); while the task complexity, reflected in the information need can affect user's search behaviour (Large et al 1994). Furthermore, information source selection (Bassilli 1977), and the user's model of the system and domain impact on the search process (Michel 1994); while motivation (Solomon 1993, Jacobsen et al 1992) and the importance of the information need (Wendt 1969) also influence search duration and the effort a user will employ. Rouse and Rouse (1984) in a review of empirical studies, summarise a wide variety of variables that can effect searching behaviour, including payoff, costs of searching, resource available, amount of information sought, characteristics of the data and conflicts between documents. It appears that user behaviour is inconsistent in the search strategies adopted even for the same search need and system (Davidson 1977, Iivonen 1995). Theories of searcher behaviour have been proposed that provide explanations of aspects of end-user behaviour, such as the evolution of the user's information need and the problems of articulating a query, [Bates (1979, 1989), Markey and Atherton 1978], effective search strategies in browsing and goal directed searches [Marchionini 1995, Belkin (1987, 1993)], the linguistic problem of matching search terms with indexing terms or content of target documents through an expert intermediary (Ingwersen 1982) or cognitive aspects of IR (Kulthau 1984, Ingwersen 1996).

    Abstract
    The Alexandria Digital Library (ADL) is one of the 6 digital library projects funded by NSF, DARPA, and NASA. ADL's collection and services focus on information containing georeferences: maps, images, data sets, text and other information sources with links to geographic locations. During this study period, 3 different user interfaces were developed and tested by user groups. User feedback was collected through various formal and informal approaches and the results fed back into the design and implementation cycle. This article describes the evolution of the ADL system and the effect of user evaluation on that evolution. ADL is an ongoing project; user feedback and evaluation plans for the remainder of the project are described

    Abstract
    Digital libraries allow information access to be integrated into work processes rather than separated from them, but also have the potential to overwhelm users with excessive or irrelevant information, impairing their performance rather than improving it. With the opportunity to create new models of what a library is and how it can be used comes the challenge of improving our understanding of its patrons, their work, and the circumstances under which they perform it. In this article we offer an overview of our experiences using observational methods to learn about one class of users, expert clinicians treating patients in hospital settings. We describe the evolution of our understanding of the users and their informational tasks, and how this evolving understanding is guiding our efforts to create digital library technology. The multidisciplinary composition of our team has enriched our observations and improved the validity of our analysis and interpretations. The multiple observation methods we have employed, including "thinkaloud" scenarios in the laboratory, participant observation in the field, key Informant Interviews, and focus group sessions, have enabled us to enrich the data set, gain greater insight, and verify findings with informants. The relatively tight cycle of observation, analysis, development, and repeat observation has enabled us to iteratively and more rapidly refine our "user model" and "task model," improving, we hope, the usefulness of the technologies we are developing.

    Abstract
    The authors present a study of the real-life information needs of 59 McGill University undergraduates researching essay topics for either a history or psychology course, interviewed just after they had selected their essay topic. The interview's purpose was to transform the undergraduate's query from general topic terms, based an vague conceptions of their essay topic, to an information need-based query. To chart the transformation, the authors investigate N. J. Belkin, R. N. Oddy, and H. M. Brooks' Anomalous States of Knowledge (ASK) hypothesis (1982a, 1982b), which links the user's ASK to a relevant document set via a common code based an structural facets. In the present study an interoperable structural code based an eight essay styles is created, then notions of structural facets compatible with a highimpact essay structure are presented. The important findings of the study are: (a) the undergraduates' topic statements and terms derived from it do not constitute an effective information need statement because for most of the subjects in the study the topic terms conformed to a low-impact essay style; (b) essay style is an effective interoperable structural code for charting the evolution of the undergraduate's knowledge state from ASK to partial resolution of the ASK in an information need statement.

    Abstract
    This research draws on longitudinal network data from an online community to examine patterns of users' behavior and social interaction, and infer the processes underpinning dynamics of system use. The online community represents a prototypical example of a complex evolving social network in which connections between users are established over time by online messages. We study the evolution of a variety of properties since the inception of the system, including how users create, reciprocate, and deepen relationships with one another, variations in users' gregariousness and popularity, reachability and typical distances among users, and the degree of local redundancy in the system. Results indicate that the system is a small world characterized by the emergence, in its early stages, of a hub-dominated structure with heterogeneity in users' behavior. We investigate whether hubs are responsible for holding the system together and facilitating information flow, examine first-mover advantages underpinning users' ability to rise to system prominence, and uncover gender differences in users' gregariousness, popularity, and local redundancy. We discuss the implications of the results for research on system use and evolving social networks, and for a host of applications, including information diffusion, communities of practice, and the security and robustness of information systems.
