    Abstract
    Increased enrollments, changing student expectations, and shifting patterns of Internet access and usage continue to generate resource and administrative challenges for colleges and universities. Computer center staff and college administrators must balance increased access demands, changing system loads, and system security within constrained resources. To assess the changing academic computing environment, computer center directors from several geographic regions were asked to respond to an online questionnaire that assessed patterns of usage, resource allocation, policy formulation, and threats. Survey results were compared with data from a study conducted by the authors in 1999. The analysis includes changing patterns in Internet usage, access, and supervision. The paper also presents details of usage by institutional type and application as well as recommendations for more precise resource assessment by college administrators.

    Abstract
    This study examines end-user interactions with indexing language information during subject searching in a library catalog and their understanding of this information and its function in term selection. Participants were asked to interact with the indexing language (Library of Congress Subject Headings) and were asked to express their general understanding of the information provided and each specific type of information included in the indexing language. In addition, participants were asked to express their understanding of the function of indexing language information in term selection, its usefulness and desirability as an integrated tool into the information retrieval system during subject searching. Study findings and their implications are discussed and future research is considered.

    Abstract
    Usability evaluations and observations of users shopping at Amazon.com (http://www.amazon.com) revealed some interesting user behaviors. The mixed behavior patterns were leveraged to create an interface for an e-commerce product. The author describes some design practices for providing a scoped search interface for an e-commerce site.

    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
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

    Abstract
    In this issue Maglaughin and Sonnenwald provided 12 graduate students with searches related to the student's work and asked them to judge the twenty most recent retrieved representations by highlighting passages thought to contribute to relevance, marking out passages detracting from relevance, and providing a relevant, partially relevant or relevant judgement on each. By recorded interview they were asked about how these decisions were made and to describe the three classes of judgement. The union of criteria identified in past studies did not seem to fully capture the information supplied so a new set was produced and coding agreement found to be adequate. Twenty-nine criteria were identified and grouped into six categories based upon the focus of the criterion. Multiple criteria are used for most judgements, and most criteria may have either a positive or negative effect. Content was the most frequently mentioned criterion.

    Abstract
    This article reports on an exploratory study of the measurement of commonality in the use of variables or measures by authors and groups of authors who have reported on studies of information retrieval system users. There is some similarity to co-citation analysis in that, when 2 individual papers, or 2 authors of sveral works, use the same variables, this indicates a similarity in approach to the subject. Such usage may be a stroger indication of similarity than co-citation be cause it represents what the authors did, rather than what they say

    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
    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.
