    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
    This qualitative investigation is situated in the field of information seeking and use, and decision-making theory provided a framework for the study. In a naturalistic setting and across a range of curriculum areas, it investigated the behavior of secondary school students undertaking information search tasks. Research questions focused on students' criteria for assessing the relevance and reliability of information. Thirty-seven students between 14 and 17 years of age from a southeastern Australian school participated. The study collected data from journals; interviews, including video-stimulated recall interviews; think-aloud reports; video screen captures; and questionnaires. Data analysis culminated in grounded theory. Initial judgments of an item's relevance were based on comprehensibility, completeness of source, whether the item needed to be purchased, whether video sources were suitable, and whether factual or opinionative material met students' needs. Participants preferred information that provided topic overviews, information that linked to prior knowledge, and sources that treated topics in acceptable depth and were structured to facilitate accessibility. Students derived clues about reliability from URLs and considered the reputation of sources. The ability of an item to corroborate prior knowledge, its graphic design, its style of writing, and the perceived authority of its creators influenced participants' decisions about reliability.

    Abstract
    In conjunction with the American Society for Information Science and Technology's (ASIST) annual meeting in fall 2001, the Special Interest Group an Information Needs, Seeking, and Use (SIG USE) sponsored a research symposium an "Effective Methods for Studying Information Seeking and Use." The symposium was intended to address the SIG's goal of promoting studies of human information behavior by focusing an the research methods that can most effectively be used to study information needs, information seeking, information use, and other human information behaviors. The symposium included the presentation of six refereed articles, which were revised based an the discussion at the symposium and are included here. The six articles describe the application of a variety of research methods, singly or in combination. Some of the methods are most appropriate for studying individuals and their interactions with information, while others can be applied to studying group behaviors. The studies were conducted in a variety of settings, from a Web-searching laboratory to an archive, from hospitals to the great outdoors (i.e., forest and river sites). Each method or set of methods was applied to a particular user group, including young children, teenagers, and adults. Each article makes a unique contribution to our repertoire of research methods, as briefly reviewed here.

    Abstract
    The development of visual retrieval methods requires information about user interaction with images, including their description and categorization. This article presents the development of a categorization model for magazine images based on two user studies. In Study 1, we elicited 10 main classes of magazine image categorization criteria through sorting tasks with nonexpert and expert users (N=30). Multivariate methods, namely, multidimensional scaling and hierarchical clustering, were used to analyze similarity data. Content analysis of category names gave rise to classes that were synthesized into a categorization framework. The framework was evaluated in Study 2 by experts (N=24) who categorized another set of images consistent with the framework and found it to be useful in the task. Based on the evaluation study the framework was solidified into a model for categorizing magazine imagery. Connections between classes were analyzed both from the original sorting data and from the evaluation study and included into the final model. The model is a practical categorization tool that may be used in workplaces, such as magazine editorial offices. It may also serve to guide the development of computational methods for image understanding, selection of concepts for automatic detection, and approaches to support browsing and exploratory image search.

    Abstract
    This article reports the findings of a qualitative research study that examined professional image users' knowledge of, and interest in using, content-based image retrieval (CBIR) systems in an attempt to clarify when and where CBIR methods might be applied. The research sought to determine the differences in the perceived usefulness of CBIR technologies among image user groups from several domains and explicate the reasons given regarding the utility of CBIR systems for their professional tasks. Twenty participants (archaeologists, architects, art historians, and artists), individuals who rely on images of cultural materials in the performance of their work, took part in the study. The findings of the study reveal that interest in CBIR methods varied among the different professional user communities. Individuals who showed an interest in these systems were primarily those concerned with the formal characteristics (i.e., color, shape, composition, and texture) of the images being sought. In contrast, those participants who expressed a strong interest in images of known items, images illustrating themes, and/or items from specific locations believe concept-based searches to be the most direct route. These image users did not see a practical application for CBIR systems in their current work routines.

    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
    Analyses the technical features of the 5 main search fields of the OPAC run by Bologna University's interlibrary centre (CIB), part of the National Library Service (SBN). The CIB links about 100 academic and civil library collections on the humanities, social sciences, and science subjects. With the aid of Home Page / Helpline displays, examines how OPAC search procedures are carried out by author, title, subject, ISBN, or single library. Also explains the data filtering methods used. The CIB will soon broaden its OPAC search strategies by adopting the Florence University library OPAC research structure

    Abstract
    Presents a recently composite view of several user studies in information retrieval. Contains personal conclusions and speculations based on these studies, rather than formal statistical results, which so often are not comparable from 1 experiment to another. Suggests a taxonomy of user characteristics for such studies, in order to make results comparable. Discusses methods and effects of user training, then manner of expression of a query or information need, conduct of a search, use of the system command language or its equivalent, analysis by the user of retrieved information, and user satisfaction with outcome. Concludes with suggestions for system design and experimental methodology

    Abstract
    Hundreds of scholarly studies have investigated various aspects of Wikipedia. Although a number of literature reviews have provided overviews of this vast body of research, none has specifically focused on the readers of Wikipedia and issues concerning its readership. In this systematic literature review, we review 99 studies to synthesize current knowledge regarding the readership of Wikipedia and provide an analysis of research methods employed. The scholarly research has found that Wikipedia is popular not only for lighter topics such as entertainment but also for more serious topics such as health and legal information. Scholars, librarians, and students are common users, and Wikipedia provides a unique opportunity for educating students in digital literacy. We conclude with a summary of key findings, implications for researchers, and implications for the Wikipedia community.

    Abstract
    Reports results of the Information Access Project, funded by King's College London and the British Library, Research and Development Department, set up to examine the effects of information technology, the electronic library and the Internet on the information seeking behaviour and research behaviour of academics in higher education. The project studied a team of theoretical physicists over 2 years using a qualitative, context situation, user centred methodology. Electronic resources, primarily electronic bulletin boards and electronic mail, were used to access information in 80% of the 48 research projects, ususally in conjunction with traditional methods. Discusses the changes in information activity, changed boundaries and speeding up of the work of the research community; increased visibility for researchers; formalization of the preprint process; replacement of formal with informal peer review; improved access to more current information; and the demise in the use of libraries. Drawbacks reported include: limitations of electronic mail communication; information overload; limitations of reliance on single information sources in terms of their focus; and the reduction in creative active information seeking. The main electronic information source for the high energy physicists, used in the study, was the High Energy Physics Theory (HEPTH) pre-print bulletin board: a service designed to provide rapid access to written research information available before it is published in periodical form

    Abstract
    We present the first systematic study of the influence of time on user judgements for rankings and relevance grades of web search engine results. The goal of this study is to evaluate the change in user assessment of search results and explore how users' judgements change. To this end, we conducted a large-scale user study with 86 participants who evaluated 2 different queries and 4 diverse result sets twice with an interval of 2 months. To analyze the results we investigate whether 2 types of patterns of user behavior from the theory of categorical thinking hold for the case of evaluation of search results: (a) coarseness and (b) locality. To quantify these patterns we devised 2 new measures of change in user judgements and distinguish between local (when users swap between close ranks and relevance values) and nonlocal changes. Two types of judgements were considered in this study: (a) relevance on a 4-point scale, and (b) ranking on a 10-point scale without ties. We found that users tend to change their judgements of the results over time in about 50% of cases for relevance and in 85% of cases for ranking. However, the majority of these changes were local.

    Abstract
    This article focuses on the relevance judgments made by health information users who use the Web. Health information users were conceptualized as motivated information users concerned about how an environmental issue affects their health. Users identified their own environmental health interests and conducted a Web search of a particular environmental health Web site. Users were asked to identify (by highlighting with a mouse) the criteria they use to assess relevance in both Web search engine surrogates and full-text Web documents. Content analysis of document criteria highlighted by users identified the criteria these users relied on most often. Key criteria identified included (in order of frequency of appearance) research, topic, scope, data, influence, affiliation, Web characteristics, and authority/ person. A power-law distribution of criteria was observed (a few criteria represented most of the highlighted regions, with a long tail of occasionally used criteria). Implications of this work are that information retrieval (IR) systems should be tailored in terms of users' tendencies to rely on certain document criteria, and that relevance research should combine methods to gather richer, contextualized data. Metadata for IR systems, such as that used in search engine surrogates, could be improved by taking into account actual usage of relevance criteria. Such metadata should be user-centered (based on data from users, as in this study) and contextappropriate (fit to users' situations and tasks).

    Abstract
    This paper highlights some of the significant findings from author's PhD: "Factors affecting the end-use of electronic databases in public libraries." Public libraries have a wide range of different types of users who, unlike academic or special library users, are not necessarily information-trained (see Coles, 1998). Whereas the academic, special library user may have specific information needs that can be met by electronic sources, public library users do not necessarily have such specific information needs that can easily be identified and met. Most user surveys have tended to concentrate on the searching and retrieval aspect of information seeking behaviour, whereas this study's user survey focused more on how people perceived and related to Information and Communication Technologies (ICTs). It was not how people searched a particular electronic source, in this case CD-ROM, that was of prime interest but rather whether or not people actually used them at all and the reasons why people did or did not use electronic media. There were several reasons the study looked at CD-ROM specifically. Firstly, CD-ROM is a well established technology, most people should be familiar with CD-ROM/multimedia. Secondly, CD-ROM was, at the start of the study, the only open access electronic media widely available in public libraries. As well as examining why public library users chose to use electronic sources, the paper looks at the types of CD-ROM databases used both in the library and in general Also examined are what sort of searches users carried out. Where appropriate some of the problems inherent in studying end-users in public libraries and the difficulty in getting reliable data, are discussed. Several methods were used to collect the data. I wished to avoid limiting research to a small sample of library sites, the aim was to be as broad in scope as possible. There were two main groups of people 1 wished to look at: non-users as well as CD-ROM users

    Abstract
    Recently, the importance of application of multiple, qualitative methods has been emphasised in the field of information seeking and retrieval research. (See Fidel 1993; Vakkari 1997). One of the earliest and most ambitious attempts to apply multiple methods was the research project on information needs and information services in local authority social services departments. (Wilson & Streatfield 1977; Wilson, et al., 1979; Wilson 1981). In studies on information needs and seeking qualitative methods have gained a leading position in the 1990's (Vakkari 1997: 451). Indisputably, this is the case when looking at recent information needs, seeking and use research carried out by Algon (1997), Ellen (1998), Barry (1995), Byström (1997), Iivonen (1996), Kirk (1997), Kuhlthau (1993), Solomon (1997) and Sonnenwald and Lievrouw (1996). Furthermore, though the approach of the study is qualitative the application of quantitative techniques is not necessarily excluded. In methodological literature attention is paid to integrating qualitative and quantitative techniques. These methods are not opposite but they complement to each other. In a qualitative study various methods can be combined. Triangulation can be seen in two ways: firstly, to ascertain the validity of research; secondly, to employ the methods that are appropriate to the subject investigated. Application of triangulation in the former way aims at the full, 'objective' picture of the subject studied, while the picture obtained in the latter way is like a kaleidoscope. Thus the ultimate reason for triangulating is to gain deeper understanding of the phenomenon studied.

    Abstract
    The history of user evaluation of reference service is traced and related to other methods of reference evaluation, including librarian self report of success, behavioral guidelines, and ubobtrusive observation. The evidence to be derived from presently available user evaluations is considered in the light of criteria for a reference evaluation instrument. Concludes that reference success cannot be explained by any one group of factors, and that the best evaluation will utilize many methods
