    Abstract
    The research reported here was an exploratory study that sought to discover the effects of human individual differences an Web search strategy. These differences consisted of (a) study approaches, (b) cognitive and demographic features, and (c) perceptions of and preferred approaches to Web-based information seeking. Sixtyeight master's students used AItaVista to search for information an three assigned search topics graded in terms of complexity. Five hundred seven search queries were factor analyzed to identify relationships between the individual difference variables and Boolean and best-match search strategies. A number of consistent patterns of relationship were found. As task complexity increased, a number of strategic shifts were also observed an the part of searchers possessing particular combinations of characteristics. A second article (published in this issue of JASIST; Ford, Miller, & Moss, 2005) presents a combined analyses of the data including a series of regression analyses.

    Abstract
    A study of the "real world" Web information searching behavior of 206 college students over a 10-month period showed that, contrary to expectations, the users adopted a more passive or browsing approach to Web information searching and became more eclectic in their selection of Web hosts as they gained experience. The study used a longitudinal transaction log analysis of the URLs accessed during 5,431 user days of Web information searching to detect changes in information searching behavior associated with increased experience of using the Web. The findings have implications for the design of future Web information retrieval tools

    Abstract
    We report a naturalistic interactive information retrieval (IIR) study of 18 ordinary users in the age of 20-25 who carry out everyday-life information seeking (ELIS) on the Internet with respect to the three types of information needs identified by Ingwersen (1986): the verificative information need (VIN), the conscious topical information need (CIN), and the muddled topical information need (MIN). The searches took place in the private homes of the users in order to ensure as realistic searching as possible. Ingwersen (1996) associates a given search behaviour to each of the three types of information needs, which are analytically deduced, but not yet empirically tested. Thus the objective of the study is to investigate whether empirical data does, or does not, conform to the predictions derived from the three types of information needs. The main conclusion is that the analytically deduced information search behaviour characteristics by Ingwersen are positively corroborated for this group of test participants who search the Internet as part of ELIS.

    Abstract
    In this article, we report results of an investigation into the effect of sponsored links on ecommerce information seeking on the Web. In this research, 56 participants each engaged in six ecommerce Web searching tasks. We extracted these tasks from the transaction log of a Web search engine, so they represent actual ecommerce searching information needs. Using 60 organic and 30 sponsored Web links, the quality of the Web search engine results was controlled by switching nonsponsored and sponsored links on half of the tasks for each participant. This allowed for investigating the bias toward sponsored links while controlling for quality of content. The study also investigated the relationship between searching self-efficacy, searching experience, types of ecommerce information needs, and the order of links on the viewing of sponsored links. Data included 2,453 interactions with links from result pages and 961 utterances evaluating these links. The results of the study indicate that there is a strong preference for nonsponsored links, with searchers viewing these results first more than 82% of the time. Searching self-efficacy and experience does not increase the likelihood of viewing sponsored links, and the order of the result listing does not appear to affect searcher evaluation of sponsored links. The implications for sponsored links as a long-term business model are discussed.

    Abstract
    A survey of 4,032 youth in grades 5 through 12 was conducted to determine the impact youth's use of the Internet was having on their use of the public library. Results indicated that 100% of the youth had access to the Internet from one or more locations, and that although one quarter of the youth accessed the Internet at the public library, the public library was the least frequently used source of Internet access. For youth without Internet access at home, the public library was also the least used alternate source of access. Approximately 69% of the youth reported that they had visited a public library during the school year. Having Internet access at home did not affect whether or not youth visited the library however, Internet access at home appears to have affected the frequency with which youth visit the library. Youth without Internet access at home visited the library more frequently, whereas youth with Internet access at home visited the library less frequently. Use of the Internet also appeared to have diminished youth's need to use the public library as a source of personal information however, use of the Internet appeared not to have affected their use of the public library for school work or for recreation. Among youth, use of both the Internet and the public library appear to be complementary activities.

    Abstract
    This exploratory study contributes to research on relevance assessment by specifying criteria that are used in the judgment of information quality and credibility in Internet discussion forums. To this end, 4,739 messages posted to 160 Finnish discussion threads were analyzed. Of the messages, 20.5% contained explicit judgments of the quality of information and credibility in other messages. In the judgments, the forum participants employed both positive criteria such as validity of information and negative criteria such as dishonesty in argumentation. In the evaluation of the quality of the message's information content, the most frequently used criteria pertained to the usefulness, correctness, and specificity of information. In the judgment of information credibility, the main criteria included the reputation, expertise, and honesty of the author of the message. Since Internet discussion forums tend to emphasize the role of disputational discourse questioning rather than accepting the views presented by others, mainly negative criteria were used in the judgments. The generality of our claims is limited because we chose forums that focused on sensitive and value-laden topics; future work could explore credibility and quality judgment in other forums and forumlike venues such as question and answer sites as well as exploring how quality and credibility judgments interact with other aspects of forum use.

    Abstract
    This study examines the influence of time constraints on Internet and Web search goals and search behavior. Specifically, it looks at the searching behavior of public library Internet users who, previously limited to 30 minutes per Internet session, are given an unlimited amount of time for use. Interviews and observations were conducted with 34 participants searching on their own queries. Despite an increase in the time allowed for searching, most people spent less than 30 minutes on the Internet, carrying out tasks like paying bills, shopping, browsing, and making reservations. Those who took more than 30 minutes were looking for jobs or browsing. E-mail use was universal. In this context, influences like time-dependent and time-independent tasks, use of search hubs to perform more efficient searches, and search diversity were recorded. Though there are a number of large and small studies of Internet and Web use, few of them focus on temporal influences. This study extends knowledge in this area of inquiry.

    Abstract
    Reports on research into the information-seeking habits of primary schoolchildren conducted under operational conditions. Three workstations with Internet access were installed in a grade-six classroom in suburban Montreal. After a short introductory training session for the entire group followed by short individual sessions for each student, 53 students, working in small groups, used these workstations over a six-week period to seek information on the Web of relevance to a class project assigned by their teacher. The project dealt with the Winter Olympic Games (recently completed at that time). The student objective was to locate relevant information for a poster and an oral presentation on one of the sports represented at the Games. All screen activity was directly captured on videotape and group conversations at the workstation were audiotaped. Demographic and computer literacy information was gathered in a questionnaire. This paper presents a map of the information-seeking landscape based upon an analysis of the descriptive statistics gathered from the Web searches. It reveals that the novice users favored browsing over analytic search strategies, although they did show some sophistication in the construction of the latter. Online help was ignored. The children demonstrated a very high level of interactivity with the interface at the expense of thinking, planning and evaluating. This is a preliminary analysis of data which will subsequently be expanded by the inclusion of qualitative data

    Abstract
    In this paper, we report on the second part of an empirical study designed to observe how users interact with World Wide Web resources. Applying a holistic approach, the researches examine users' cognitive, affective, and physical behaviors during user-Web interaction in order to understand better the nature of information retrieval on the Web, the needs of Web users, and the problem-solving strategies Web users employ. From analyses and the participant verbalizations collected during monitored searches, the researchers developed a taxonomy of problem solving strategies. The coding scheme was developed based on a content analysis of the integrated process data. Information from triangulation follow-up with participants via anonymously completed questionnaires, the taxonomy, and analyses of search transcripts were collected to determine 1) what problems users encountered during the interaction and how users solved these problems; and 2) which problem-solving strategies Web users considered and selected for finding factual information. The focus of the coding was on the participants' cognitive, affective, and physical behaviors in response to the components of the problems encountered, which included problems of the following types: Web interfaces, users' mental models, and the Web information sources. Searching behavior and problem-solving patterns are described and interpreted within the relevant situational context and the problems users encountered are identified and analyzed. Both the problems users faced and their problem-solving approaches endeavored evidence a strong reliance on mental models of the features available on sites, the location of those features, and other interface design concepts

    Abstract
    Purpose - A common criticism of research into information seeking on the internet is that information seekers are restricted by the demands of the researcher. Another criticism is that the search topics, are often imposed by the researcher, and; particularly when working with children, domain knowledge could be as important as information-seeking skills. The research reported here attempts to address both these problems. Design/methodology/approach - A total of 15 children, aged 11 to 16, were each set three "think aloud" internet searches. In the first, they were asked to recall the last time they had sought information on the internet, and to repeat the search. For the second, they were given a word, asked to interpret it, then asked to search for their interpretation. For the third, they were asked to recall the last time they had been unsuccessful in a search, and to repeat the search. While performing each task, the children were encouraged to explain their actions. Findings - The paper finds that the factors that determined a child's ability to search successfully appeared to be: the amount of experience the child had of using the internet; the amount of guidance, both from adults and from peers; and the child's ability to explore the virtual environment, and to use the tools available for so doing. Originality/value - Many of the searches performed by participants in this paper were not related to schoolwork, and so some of the search approaches differed from those taught by teachers. Instead, they evolved through exploration and exchange of ideas. Further studies of this sort could provide insights of value to designers of web environments.

    Abstract
    Reports results of a survey, conducted by the State University of New York and Albany Library, to investigate the effects of gender, college status and prior Internet experience on the use of Internet resources. The subjects were 96 randomly selected users using the library's Internet terminals during the first 2 months of 1995. The majority of users were found to share the following characteristics: male undergraduates affiliated with the social sciences; and novice users who have less than 6 months experience. Respondents felt strongly that the Internet is useful, and has been an important resource for their research and assignment. Users have high expectations of searching capabilities, while they feel neutral or disappointed with browsing. Results indicate that libraries should provide access to the Internet and suggest that libraries should take the lead in developing searchable indexes and making databases better organized for the ease and effectiveness of browsing

    Abstract
    Reports results of an evaluation of the Online at PA Libraries project (Autumn 1996 to Autumn 1997), funded by Bell Atlantic and administered by the Pennsylvania Dept. of Education's Office of Commonwealth Libraries and the Schuylkill Intermediate Unit, which has had a significant impact on the provision of Internet based information services and resources to Pennsylvania public library users. 4 surveys were conducted: a survey to assess the participating libraries' expectations concerning the project; a user survey to determine user satisfaction, demographic and overall project and Internet assessment; and 2 training evaluation surveys conducted at the start and at the follow up stage of the project. The project has provided a statewide demonstration of what can be done to improve quickly and significantly the statewide public library services; to connect public libraries to the Internet and provide a range of new services and resources to their communities; and to 'junpstart' libraries, librarians and citizens into the global networked society

    Abstract
    Focuses on how satisfied Australian academics are when they use the Internet to search for information. Results validated magnitude estimates of user satisfaction with information seeking on the Internet. Testing the validity and reliability magnitude estimation as a technique for gathering and analysing interval data on satisfaction with information seeking was key to the investigation. Data for user satisfaction were then associated with end user characteristics like training, frequency of use and expectation of success. They have a high expectation of success when they engage in information seeking on the Internet and are satisfied with the process regardless of how frequently they use the network or whether or not they have formal training

    Abstract
    This study develops three alternative models of academic library Web site usage based on the Technology Acceptance Model (TAM). The three alternative models depict relationships among various intrinsic and extrinsic determinant factors of an academic library's Web site usage. The four factors included in the models are perceived ease-of-use, perceived usefulness, service functionality, and task functionality. These four factors are hypothesized to affect directly or indirectly both factors of satisfaction and intention-to-use. LISREL analysis using survey data shows that the best-fit model is the Dual Mediation Impact Model. Research and managerial implications for the academic library are discussed. Future research directions and limitations also are provided.

    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
    Examines the problem of a compelling online news delivery system by focusing on how mass media audiences and online users differ in their assessment of news. It employed a 2-wave USA national survey to study the perception of interactivity in mass media and computer networks and its relationship to the assessment of news. The 1st wave looked a national probability sample, ahile the 2nd targeted viewers of NBC Nightly News who responded to the show via e-mail. NBC respondents rated mass media to be less interactive, while they rated computer communication more interactive than the national sample. The NBC group also rated mass media news less important and of lower quality than did the national sample. Interactivity ratings did not predict mass media credibility assessment for either group. However, respondents who defined interactivity as cybernetic feedback or who contacted NBC by e-mail rated computer communication to be more credible than thos who did not

    Abstract
    This study sought to investigate the effects of cognitive style (field dependent and field independent) and on-line database search experience (novice and experienced) on the WWW search performance of undergraduate college students (n=48). It also attempted to find user factors that could be used to predict search efficiency. search performance, the dependent variable was defined in 2 ways: (1) time required for retrieving a relevant information item, and (2) the number of nodes traversed for retrieving a relevant information item. the search tasks required were carried out on a University Web site, and included a factual task and a topical search task of interest to the participant. Results indicated that while cognitive style (FD/FI) significantly influenced the search performance of novice searchers, the influence was greatly reduced in those searchers who had on-line database search experience. Based on the findings, suggestions for possible changes to the design of the current Web interface and to user training programs are provided
