- Abstract
- This study grew out of a need for better research based understanding of information seeking and use in a specific context. Several researchers in library and information studies (LIS) pointed out the predominance of research on information needs and information seeking and expressed a need for the study of information use (i.a. Kuhlthau 1993; Vakkari 1997; Wilson 1981). The role of context for information seeking behaviour has been stressed (i.a. Dervin 1997; Wilson 1981, 1994). The complex process of information seeking and use in learning contexts needs further exploration, according to i.a. Kuhlthau (1993). My research project investigated how students used information and what they learnt from the information they retrieved and used for an assignment. The aim of the project was to study information seeking through an explorative investigation of the interaction between information seeking and use and learning outcomes.

- Abstract
- In this paper results of a field study into the need for research information of different user groups are presented: scientists, policy makers and policy researchers, industry and media. Main questions of semi-structured interviews were: what kind of research information users need, what kind of research information resources are used and which information resources are missing at the moment. User groups are missing for a diversity of reasons the overview of research, experts and institutes in the different scientific fields. Especially for the accessibility and transparency of the scientific world these overviews are reported to be needed. Neither Google nor any of the research institutes or policy research organisations are able to present surveys for different science fields at the moment. Giving users the possibility to search, browse and navigate through accessible and more specialised layers of research information might give answers to different user groups simultaneously.

- Abstract
- In information needs, seeking and use (INSU) research, individuals have most commonly been perceived as users (e.g., Kuhlthau, 1991; Dervin & Nilan, 1986; Dervin, 1989; Belkin, 1980). The concept user originates from the user of libraries and other information services and information systems. Over the years the scope of the concept has become wider and it is nowadays often understood in the sense of seekers of information (e.g., Wilson, 1981; Marchionini, 1995) and users of information (e.g., Streatfield, 1983). Nevertheless, the concept has remained ambiguous by being on the one hand universal and on the other hand extremely specific. The purpose of this paper is to map and evaluate views on people whose information behaviour has been in one way or another the core of our research area. The goal is to shed some light on various relationships between the different aspects of doers in INSU studies. The paper is inspired by Dervin's (1997) analysis of context where she identified among other themes the nature of subject by contrasting a `transcendental individual' with a `decentered subject', and Talja's (1997) presentation about constituting `information' and `user' from the discourse analytic viewpoint as opposed to the cognitive viewpoint. Instead of the metatheoretical approach applied by Dervin and Talja, a more concrete approach is valid in the present analysis where no direct arguments for or against the underlying metatheories are itemised. The focus is on doers in INSU studies leaving other, even closely-related concepts (i.e., information, information seeking, knowledge etc.), outside the scope of the paper.

- Abstract
- Browsing is considered to be unstructured and human-driven, although not a cognitively intensive process. It is conducted using systems that facilitate considerable user-system interactivity. Cued by the content, people immerse themselves in a topic of interest and meander from topic to topic while concurrently recognising interesting and informative information en route. They seem to seek and gather information in a purposeless, illogical and indiscriminate manner. Typical examples of these ostensibly random acts are scanning a non-fiction book, examining the morning newspaper, perusing the contents of a business report and scavenging the World Wide Web. Often the result is the acquisition of new information, the rejection or confirmation of an idea, or the genesis of new, perhaps not-wholly-formed thoughts about a topic. Noteworthy about this approach is that people explore information without having consciously structured queries or explicit goals. This form of passive information interaction behaviour is defined as acquiring and gathering information while scanning an information space without a specific goal in mind (Waterworth & Chignell, 1991; Toms, 1997), and for the purposes of this study, is called browsing. Traditionally, browsing is thought of in two ways: as a physical process - the action taken when one scans a list, a document, or a set of linked information nodes (e.g., Fox & Palay, 1979; Thompson & Croft, 1989; Ellis, 1989), and as a conceptual process, information seeking when the goal is ill-defined (e.g., Cove & Walsh, 1987). Browsing is also combined with searching in an integrated information-seeking process for retrieving information (e.g., Ellis, 1989; Belkin, Marchetti & Cool, 1993; Marchionini, 1995; Chang, 1995). Each of these cases focuses primarily on seeking information when the objective ranges from fuzzy to explicit.

- 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 goal of this study is to understand whether providing a search intermediary familiar with a problem domain and its topical structure would support a user's Web searching tasks, especially complicated tasks with multifaceted topics, and whether the order of searching tasks or system usage influences their successful completion. This study investigates the effect of two factors, the interaction mode and the display layout, on the three main measures of the user's Web searching behaviors: effectiveness, efficiency, and usability. Two interaction modes are compared, mediation via a domain-specific document collection versus nonmediated search, and two display layouts, a combination of browsing-supporting hierarchic display and ranked list of results versus the simple linear list of search results. The results are analyzed in the Flow theory point of view; they were analyzed by order of the tasks and system usage order. The findings of this study contribute to a better understanding of how the mediation system and/or the combined display support a Web information user.

- Abstract
- School library media specialists do not know which search strategies are most appropriate for the new full-text CD-ROM databases. Reports an experiment conducted to examine the effectiveness of 2 search strategies - analytical and browse strategies - for information seeking and use among high school students using an electronic full-text ancyclopedia for the search task. The experiment sought to determine whether: a short training session in a particular information strategy allows an information seeker to form an adequate mental model of the search task; and a simple 'browse' model compare favourably with a more 'analytical' model for information seeking in a full-text online environment. Both strategies proved effective for finding relevant information yet each demonstrated distinct advantages and disadvantages. Recommends that as new technologies are introduced, school library media specialists should conduct careful observations and controlled comparisons of how students use these systems
