    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
    I started my professional career in library and information science because of my great interest in knowledge organization. The more experience I gained in the profession, the more I realized how crucial it is to understand which organization would be best for each group of users. This in turn requires an understanding of how users seek information. And so now my focus is an studying information seeking and searching behavior. Throughout the relatively long course of changing my focus, I followed Pauline Cochrane's writings. Now I can say that she has been among the first to have a "user-centered approach" to knowledge organization, and she has used the term three years before it became a mainstream phrase. The following is a short discussion about the usercentered approach which was presented in a workshop in 1997.

    Abstract
    This paper is the second part of a two-part paper, which examines the transition to the electronic information era in academia. Seeks to establish from the published literature to what extent university researchers have accepted, and adapted to, the changes wrought in information activity by seemingly endless technological developments. Within the wider context of the impact of the changing information environment on each of the three clearly discernible components of academic research (the creation of knowledge and standards, the preservation of information, and the communication of knowledge and information to others), disciplinary-rooted differences in the conduct of research and their influence on information needs are identified, and the resulting inter- and intra-individual variations in researchers' information seeking behaviour are explored. Reviewing a large number of studies investigating the integration of electronic media into academic work, an attempt is made to paint the picture of academics' progressively harnessing the new technologies to scholarly information gathering endeavours, with the expressed hope of affording some insight into the directions and basic trends characterising the information activity of university faculty in an increasingly electronic environment.

    Abstract
    Critiques of subject access standards in LIS literature have addressed biases of gender, sexuality, race, age, ability, ethnicity, language and religion as limits to the representation of diversity and to effective library service for diverse populations. The current study identifies and analyzes this literature as a basis for ameliorating systemic bias and to gather the existing literature for wider accessibility. The study analyzes five quantitative variables: standards discussed, categories of problems, marginalized groups and topics discussed, date, and basis of conclusions (research or experience). Textual analysis reveals that basic tenets of subject access-user-focused cataloguing, objectivity, and standardization-are problematized in the literature and may be the best starting point for future research. In practice, librarians can work to counteract systemic problems in the careful and equitable application of standards and their adaptation to local contexts.

    Abstract
    This study focuses on the task as a fundamental factor in the context of information seeking. The purpose of the study is to characterize kinds of tasks and to examine how different kinds of task give rise to different kinds of information-seeking behavior on the Web. For this, a model for information-seeking behavior was used employing dimensions of information-seeking strategies (ISS), which are based on several behavioral dimensions. The analysis of strategies was based on data collected through an experiment designed to observe users' behaviors. Three tasks were assigned to 30 graduate students and data were collected using questionnaires, search logs, and interviews. The qualitative and quantitative analysis of the data identified 14 distinct information-seeking strategies. The analysis showed significant differences in the frequencies and patterns of ISS employed between three tasks. The results of the study are intended to facilitate the development of task-based information-seeking models and to further suggest Web information system designs that support the user's diverse tasks.

    Abstract
    This article reviews studies, conducted between 1995 and 2000, on Web search behavior. These studies reported on children as well as on adults. Most of the studies on children described their interaction with the Web. Research on adult searchers focused on describing search patterns, and many studies investigated effects of selected factors on search behavior, including information organization and presentation, type of search task, Web experience, cognitive abilities, and affective states. What distinguishes the research on adult searchers is the use of multiple data-gathering methods. The research on Web search behavior reflects researchers' commitment to examine users in their information environment and exhibits rigor in design and data analysis. However, many studies lack external validity. Implications of this body of research are discussed.

    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 results of a small qualitative study of gay and lesbian information users suggest that facet analysis as it is increasingly practised in the field of information architecture provides a promising avenue for improving information access to gay and lesbian information resources. Findings indicated that gay and lesbian information users have an acute sense of categorization grounded in the need to identify gay-positive physical and social spaces, and in their finely-honed practices of detecting gay "facets" to general information themes. They are also, however, very flexible and adaptable in their application of gay-related facet values, which suggests that browsing systems will have to be designed with considerable care.
    Content
    1. Introduction The title of this paper is taken from a TV show which has gained considerable popularity in North America: A Queer Eye for the Straight Guy, in which a group of gay men subject a helpless straight male to a complete fashion makeover. In facet analysis, this would probably be seen as an "operation upon" something, and the Bliss Bibliographic Classification would place it roughly two-thirds of the way along its facet order, after "types" and "materials," but before "space" and "time." But the link between gay communities and facet analysis extends beyond the facetious title. As Web-based information resources for gay and lesbian users continue to grow, Web sites that cater to, or at least refrain from discriminating against gay and lesbian users are faced with a daunting challenge when trying to organize these diverse resources in a way that facilitates congenial browsing. And principles of faceted classification, with their emphasis an clear and consistent principles of subdivision and their care in defining the order of subdivisions, offer an important opportunity to use time-honoured classification principles to serve the growing needs of these communities. If faceted organization schemes are to work, however, we need to know more about gay and lesbian users, and how they categorize themselves and their information sources. This paper presents the results of an effort to learn more.

    Abstract
    This article presents an overview of some of the methodology used in a project that examined children's understanding of library information and how those perspectives change in the first 5 years of formal schooling. Because our understanding of information is reflected in the manner in which we classify, or typify, that information in order to view the library collection from a child's perspective children were invited to shelve (i.e., classify) terms representative of library books and then to label those categories. The resulting shelf categories help us to see library information from a child's perspective. Data collection using group dialog, visual imagery, narrative, cooperative learning techniques, and hands-on manipulatives is described for one session of a project in which children used induction to form concepts related to knowledge organization in a hypothetical library. Analysis for this session included use of hierarchical clustering and multidimensional scaling to examine and compare children's constructions for qualitative differences an several grade levels. Following the description of data collection methods and analysis, a discussion focuses an the reasons for using these particular methods of data collection with a child population.

    1. Introduction A small study is described which investigated the vocabulary as reflected in the knowledge structures of novices. The research was conducted in order to understand how knowledge organization tools may be designed to meet the needs of novices in the GROW digital library. GROW is the Geo-technical, Rock, and Water digital library, the first step in the establishment of a National Civil Engineering Resources Library (NCERL). Digital libraries are complex entities that have many components: besides the collections of individual resources and the interface to these resources, they have organization, labelling, navigation and searching systems. Controlled vocabularies and thesauri are often the invisible components. This study is based an the premise that the controlled vocabulary influences the above mentioned related components in the digital library. We felt that it was important to understand the knowledge structures of a primary group of user, the novice - the student learner - who is new to the domain. A great deal of research has been done about how people learn and how people use information, but fewer studies link science knowledge structures, vocabulary, and language use.

    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
    Four focus groups were held with young Web users (10 to 13 years of age) to explore design criteria for Web portals. The focus group participants commented upon four existing portals designed with young users in mind: Ask Jeeves for Kids, KidsClick, Lycos Zone, and Yahooligans! This article reports their first impressions on using these portals, their likes and dislikes, and their suggestions for improvements. Design criteria for children's Web portals are elaborated based upon these comments under four headings: portal goals, visual design, information architecture, and personalization. An ideal portal should cater for both educational and entertainment needs, use attractive screen designs based especially on effective use of color, graphics, and animation, provide both keyword search facilities and browsable subject categories, and allow individual user personalization in areas such as color and graphics

    Abstract
    Bilal, in this third part of her Yahooligans! study looks at children's performance with self-generated search tasks, as compared to previously assigned search tasks looking for differences in success, cognitive behavior, physical behavior, and task preference. Lotus ScreenCam was used to record interactions and post search interviews to record impressions. The subjects, the same 22 seventh grade children in the previous studies, generated topics of interest that were mediated with the researcher into more specific topics where necessary. Fifteen usable sessions form the basis of the study. Eleven children were successful in finding information, a rate of 73% compared to 69% in assigned research questions, and 50% in assigned fact-finding questions. Eighty-seven percent began using one or two keyword searches. Spelling was a problem. Successful children made fewer keyword searches and the number of search moves averaged 5.5 as compared to 2.4 on the research oriented task and 3.49 on the factual. Backtracking and looping were common. The self-generated task was preferred by 47% of the subjects.
