    Abstract
    Structured document retrieval makes use of document components as the basis of the retrieval process, rather than complete documents. The inherent relationships between these components make it vital to support users' natural browsing behaviour in order to offer effective and efficient access to structured documents. This paper examines the concept of best entry points, which are document components from which the user can browse to obtain optimal access to relevant document components. It investigates at the types of best entry points in structured document retrieval, and their usage and effectiveness in real information search tasks.

    Abstract
    Evaluates 2 design ideas concerning information retrieval systems (IRS) for professionals with the aim of supporting a professional's document handling and to facilitate the evolution of the IRS, allowing it to be modified in a straightforward and flexible way as new requirements arise. Illustrates the viability of those design ideas through a case study concerning the development of a prototype legal IRS based on a leading body of Danish lwas. Important facilities in the prototype include a dynamic thesaurus, a dynamic classification structure and personal notes. The prototype is built using a relational database, not inverted files as in the majority of IRS

    Abstract
    Multimedia retrieval is a complex and to some extent still unexplored area. Based on a full year of e-mail requests addressed to a large film archive this study analyses what types of information needs real users have and how these needs are expressed. The findings include that the requesters make use of a broad range of need attributes in specifying their information needs. These attributes relate to the production, content, subject, context and screening of films. However, a few attributes - especially title, production year and director - account for the majority of the attribute instances. Further, as much as 43 per cent of the requests contain no information about the context that gives rise to the request. The current indexing of the archived material is restricted to production-related attributes, and access to the material is, thus, frequently dependent on the archivists' extensive knowledge of the archived material and films in general.

    Abstract
    Experimentation is the process of trying something out to discover what happens. It is a widespread information practice, yet often bypassed in information-behavior research. This article argues that experimentation complements prior knowledge, documents, and people as an important fourth class of information sources. Relative to the other classes, the distinguishing characteristics of experimentation are that it is a personal-as opposed to interpersonal-source and that it provides "backtalk." When the information seeker tries something out and then attends to the resulting situation, it is as though the materials of the situation talk back: They provide the information seeker with a situated and direct experience of the consequences of the tried-out options. In this way, experimentation involves obtaining information by creating it. It also involves turning material and behavioral processes into information interactions. Thereby, information seeking by experimentation is important to practical information literacy and extends information-behavior research with new insights on the interrelations between creating and seeking information.

    Abstract
    Since common ground is pivotal to collaboration, this paper proposes to define collaborative information seeking as the combined activity of information seeking and collaborative grounding. While information-seeking activities are necessary for collaborating actors to acquire new information, the activities involved in information seeking are often performed by varying subgroups of actors. Consequently, collaborative grounding is necessary to share information among collaborating actors and, thereby, establish and maintain the common ground necessary for their collaborative work. By focusing on the collaborative level, collaborative information seeking aims to avoid both individual reductionism and group reductionism, while at the same time recognizing that only some information and understanding need be shared.

    Abstract
    Collaborative information seeking is integral to many professional activities. In hospital work, the medication process encompasses continual seeking for information and collaborative grounding of information. This study investigates breakdowns in collaborative information seeking through analyses of the use of the electronic medication record adopted in a Danish healthcare region and of the reports of 5 years of medication incidents at Danish hospitals. The results show that breakdowns in collaborative information seeking is a major source of medication incidents, that most of these breakdowns are breakdowns in collaborative grounding rather than information seeking, that the medication incidents mainly concern breakdowns in the use of records as opposed to oral communication, that the breakdowns span multiple degrees of separation between clinicians, and that the electronic medication record has introduced risks of new kinds of breakdown in collaborative information seeking. In working to prevent and recover from breakdowns in the seeking and sharing of information a focus on collaborative information seeking will point toward collaborative, organizational, and systemic reasons for breakdown and areas for improvement, rather than toward individual error.

    Abstract
    Purpose The purpose of this paper is to investigate how four international students at a Danish university cope with their study-related and everyday information needs, behaviorally as well as affectively, and how their information seeking blends with their cross-cultural adaptation. Design/methodology/approach Each of the four participants contributed ten diaries and took part in three interviews during the first semester of their stay. Findings International students' information needs and seeking behavior are shaped by their host university but also by cross-cultural, personal and situational issues. While the cross-cultural issues set international students apart from domestic students, the personal and situational issues create individual differences that call for more individually tailored support. The studied international students lacked information about both study-related and everyday issues. These two types of issues were intertwined and experienced as equally stressful. However, study-related information needs were more important, whereas everyday information needs were more difficult to resolve. In addition, participants tended to feel on their own when it came to finding needed information, but studying abroad also had elements of personal growth in meeting life's challenges. Research limitations/implications More participants are needed to investigate how international students' information seeking evolves over time. Originality/value This study contributes detailed information about international students' study-related and everyday information seeking during their first semester abroad. The study has implications for everyday-life studies of international students' information behavior and the international classroom in general.

    Abstract
    Makerspaces are places for construction and creative expression using tools such as 3D printers, laser cutters, and sewing machines. In this study, we investigate how makers obtain information for their makerspace projects. The study focuses on four sources of information: people, documents, experimentation, and prior knowledge. On the basis of interviews with 13 makers, we analyze their use of these information sources in relation to different knowledge areas, creative-process stages, and relevance criteria. Our main findings are that (a) experimentation is a prime source of information, (b) ease and pleasure are the dominant relevance criteria, (c) process and situation receive little attention, and (d) information sources vary across process stages. Specifically, experimentation is the dominant information source during the construction stage. In addition, the relevance criteria show that the makers turn to people because it is pleasurable, to documents because it is easy, and to experimentation because it results in quality products. These results emphasize the importance of experimentation and suggest that it warrants closer attention in studies of the information behavior of makers and, more broadly, creative professionals.

    Abstract
    Expertise seeking is the activity of selecting people as sources for consultation about an information need. This review of 72 expertise-seeking papers shows that across a range of tasks and contexts people, in particular work-group colleagues and other strong ties, are among the most frequently used sources. Studies repeatedly show the influence of the social network - of friendships and personal dislikes - on the expertise-seeking network of organisations. In addition, people are no less prominent than documentary sources, in work contexts as well as daily-life contexts. The relative influence of source quality and source accessibility on source selection varies across studies. Overall, expertise seekers appear to aim for sufficient quality, composed of reliability and relevance, while also attending to accessibility, composed of access to the source and access to the source information. Earlier claims that seekers disregard quality to minimise effort receive little support. Source selection is also affected by task-related, seeker-related, and contextual factors. For example, task complexity has been found to increase the use of information sources whereas task importance has been found to amplify the influence of quality on source selection. Finally, the reviewed studies identify a number of barriers to expertise seeking.

    Abstract
    Purpose Information seeking is often performed in collaborative contexts. The research into such collaborative information seeking (CIS) has been proceeding since the 1990s but lacks methodological discussions. The purpose of this paper is to analyze and discuss methodological issues in existing CIS studies. Design/methodology/approach The authors systematically review 69 empirical CIS studies. Findings The review shows that the most common methods of data collection are lab experiments (43 percent), observation (19 percent) and surveys (16 percent), that the most common methods of data analysis are description (33 percent), statistical testing (29 percent) and content analysis (19 percent) and that CIS studies involve a fairly even mix of novice, intermediate and specialist participants. However, the authors also find that CIS research is dominated by exploratory studies, leaves it largely unexplored in what ways the findings of a study may be specific to the particular study setting, appears to assign primacy to precision at the expense of generalizability, struggles with investigating how CIS activities extend over time and provides data about behavior to a larger extent than about reasons, experiences and especially outcomes. Research limitations/implications The major implication of this review is its identification of the need for a shared model to which individual CIS studies can contribute in a cumulative manner. To support the development of such a model, the authors discuss a model of the core CIS process and a model of the factors that trigger CIS. Originality/value This study assesses the current state of CIS research, provides guidance for future CIS studies and aims to inspire further methodological discussion.
