    Abstract
    During the fall 2001 semester 15 first-year undergraduates were interviewed about their information-seeking behavior. Undergraduates completed a short-answer questionnaire, the Measure of Epistemological Reflection, measuring their epistemological beliefs and searched the Web and an online public access catalog using tasks from the Reflective Judgment Interview that assessed their reflective judgment level. Undergraduates talked aloud while searching digital environments about the decisions they were making about the information they encountered while transaction analyses software (Lotus ScreenCam) recorded both their search moves and their decision-making through verbal protocol analysis. Analyses included examining the relationship between undergraduates' epistemological beliefs and reflective judgment and how they searched for information in these digital environments. Results indicated that there was a relationship between epistemological beliefs and reflective judgment and information-seeking behavior. Undergraduates' at higher stages of epistemological development exhibited the ability to handle conflicting information sources and to recognize authoritative information sources.

    Abstract
    User studies provide libraries with invaluable insight into their users' information needs and behaviors, allowing them to develop services that correspond to these needs. This insight has become even more important for libraries since the advent of the Internet. The Internet has brought about a development of information technologies and electronic information sources that have had a great impact on both the ways users search for information and the ways libraries manage information. Although humanists represent an important group of users for academic libraries, research studies into their information-seeking behavior since the advent of the Internet have been quite scarce (Ellis & Oldman, 2005) in the past decade. This study presents updated research on a group of humanists, Jewish studies scholars living in Israel, as information users in the digital age based on two categories: (a) the use of formal and informal information channels, and (b) the use of information technologies and their impact on humanistic research.

    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
    The article employs deep log analysis (DLA) techniques, a more sophisticated form of transaction log analysis, to demonstrate what usage data can disclose about information seeking behaviour of virtual scholars - academics, and researchers. DLA works with the raw server log data, not the processed, pre-defined and selective data provided by journal publishers. It can generate types of analysis that are not generally available via proprietary web logging software because the software filters out relevant data and makes unhelpful assumptions about the meaning of the data. DLA also enables usage data to be associated with search/navigational and/or user demographic data, hence the name 'deep'. In this connection the usage of two digital journal libraries, those of EmeraldInsight, and Blackwell Synergy are investigated. The information seeking behaviour of nearly three million users is analyzed in respect to the extent to which they penetrate the site, the number of visits made, as well as the type of items and content they view. The users are broken down by occupation, place of work, type of subscriber ("Big Deal", non-subscriber, etc.), geographical location, type of university (old and new), referrer link used, and number of items viewed in a session.

    Abstract
    Purpose - This study aims to investigate the effects of different search and browse features in digital libraries (DLs) on task interactions, and what features would lead to poor user experience. Design/methodology/approach - Three operational DLs: ACM, IEEE CS, and IEEE Xplore are used in this study. These three DLs present different features in their search and browsing designs. Two information-seeking tasks are constructed: one search task and one browsing task. An experiment was conducted in a usability laboratory. Data from 35 participants are collected on a set of measures for user interactions. Findings - The results demonstrate significant differences in many aspects of the user interactions between the three DLs. For both search and browse designs, the features that lead to poor user interactions are identified. Research limitations/implications - User interactions are affected by specific design features in DLs. Some of the design features may lead to poor user performance and should be improved. The study was limited mainly in the variety and the number of tasks used. Originality/value - The study provided empirical evidence to the effects of interaction design features in DLs on user interactions and performance. The results contribute to our knowledge about DL designs in general and about the three operational DLs in particular.

    Abstract
    This study seeks to explore and report international business students' perceptions and expectations of electronic library services at the University of Illinois at Urbana-Champaign. A total of 143 international business students an campus volunteered to fill out a survey. The results were analyzed using descriptive statistics as weIl as inferential statistics such as t-tests and correlation. A significant portion of international business students has no prior experience with electronic library services in their home countries. Moreover, about a half of international business students go to libraries other than the Business and Economics Library, partly because they provide better environment for study. Although electronic resources are available without the constraint of location, providing reference services for those who do not use the Business and Economics Library becomes a challenge. Virtual reference is an excellent tool, but most international business students do not see it as an important library service. Based an the results, implications for information literacy and virtual reference service are discussed.

    Abstract
    This study presents a test of the Anxiety-Expectation Mediation (AEM) model of library anxiety. The AEM model contains variables that are directly or indirectly related to information search performance, as measured by students' scores an their research proposals. This model posits that library anxiety and self-perception serve as factors that mediate the relationship between performance in writing a research proposal and other cognitive, personality, and demographic variables. The model was tested using 225 graduate students enrolled in several sections of an introductory-level course at a midsouthern university. Structural equation modeling techniques supported the AEM model. In particular, library anxiety and research achievement were reciprocally related. Furthermore, library anxiety mediated the relationship between research performance and the following variables: age, grade point average, learning style, academic procrastination, and self-perception. The path analysis also revealed a direct, positive path from self-perception to research performance. In addition, self-perception moderated the relationship between research achievement and academic procrastination, perfectionism, and hope. The AEM model of library anxiety suggests that Wine's (1980) Cognitive-Attentional-Interference theory, Onwuegbuzie, Jiao, and Bostick's (in press) ILP model of library anxiety, and Bandura's (1977) self-efficacy theory can be applied to the library and information context. Findings are discussed within the framework of current social-psychological models of educational achievement.

    Abstract
    As libraries face increasing competition in providing information, we must insure that our library systems are usable, effective, efficient, and perhaps even enticing. How do librarians know that systems give users what they need and want? One way is usability testing. Usability testing has been around the computer industry for at least a decade, but library use of the method is relatively new. It has been a common perception that library systems were designed for librarians. Even if the user was considered, it was from the perspective of librarians who worked with the user. Those perceptions were anecdotal, and librarians frequently disagreed with one another about user behavior and knowledge.

    Abstract
    This second part of a two-part article establishes a model of the mediating factors that influence student information behavior concerning the electronic or digital information sources used to support learning. This part discusses the findings of the Joint Information Systems Committee User Behavior Monitoring and Evaluation Framework (1999-2004) and development of a model that includes both the individual (micro) and organizational (macro) factors affecting student information behavior. The macro factors are information resource design, information and learning technology infrastructure, availability and constraints to access, policies and funding, and organizational leadership and culture. The micro factors are information literacy, academics' information behavior, search strategies, discipline and curriculum, support and training, and pedagogy. We conclude that the mediating factors interact in unexpected ways and that further research is needed to clarify how those interactions, particularly between the macro and micro factors, operate.

    Abstract
    This study explored higher-order thinking processes in undergraduates using a virtual library. Ten undergraduates pursuing topics pertaining to their academic work were interviewed and observed as they used GALILEO (GeorgiA Library LEarning Online, a virtual library containing many scholarly databases). Specifically, the study focused on relevance judging, evaluation (critical thinking), and decision making. We found a high degree of intermingling between relevance judging and evaluation, along with a number of strategies participants used to assist them in both thinking processes. Also, participants made decisions through one of three avenues in each of their appraisals of online resources.

    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
    During the feasibility study into a National Union catalogue for the UK (UKNUC), a questionnaire survey was undertaken of the needs of both academic staff in higher education and library staff. A response rate of 40-50 per cent was achieved, 846 questionnaires being returned for academics and 724 for librarians. The analysis suggests that a UKNUC would be highly valued and heavily used by all categories. Academics felt it would have a positive effect on their information searching, and wished to include the holdings of the British Library, and libraries of both the major research universities and the "traditional" universities. They wanted it to be comprehensive and easy to use, to include locations of both books and journals, and to facilitate subject collection searching. Library staff have similar priorities to academics, although there are more variations by sector and a recognition of a UKNUC's value as a potential source of bibliographic records.

    Abstract
    Describes key aspects of the methodology and outcomes of the JISC User Behaviour Monitoring and Evaluation Framework in its first three annual cycles (1999-2002). The Framework was initiated to assure the JISC that their investment in digital content and network infrastructure facilitates use and learning, and to identify barriers and facilitators to the use of electronic information services (EIS). Key Framework outcomes are: a multi-dimensional across sector methodology for the continued monitoring of user behaviour in respect of EIS and the factors that impact on that behaviour; a profile of user behaviour in respect of EIS over the three annual cycles of the Framework; the EIS Diagnostic Toolkit that can be used to benchmark development in the provision and use of EIS in specific disciplines or at specific institutions; a methodology for monitoring, and a profile of the EIS resources available to higher and further education users; and a summary of some of the key issues in their provision. The challenge for the future is the embedding of EIS in curricula and learning experiences.

    Abstract
    This study reports an analysis of referral URL data by the Cornell University IP address from the American Chemical Society servers. The goal of this work is to better understand the tools used and pathways taken when scientists connect to electronic journals. While various methods of referral were identified in this study, most individuals were referred infrequently and followed few and consistent pathways each time they connected. The relationship between the number and types of referrals followed an inverse-square law. Whereas the majority of referrals came from established finding tools (library catalog, library e-journal list, and bibliographic databases), a substantial number of referrals originated from generic Web searches. Scientists are also relying an local alternatives or substitutes such as departmental or personal Web pages with lists of linked publications. The use of electronic mail as a method to refer scientists directly to online articles may be greatly underestimated. Implications for the development of redundant library services such as e-journal lists and the practice of publishers to allow linking from other resources are discussed.

    Abstract
    This article reports on a model and patterns of use of a library catalog that can be accessed through the Internet. Three categories of users are identified. individuals who perform a search of the catalog, tourists who look only at opening pages of the library catalog's site, and Web spiders that come to the site to obtain pages for indexing the Web. A number of types of use activities are also identified, and can be grouped with the presearch phase (which takes place before any searching begins): the search phase, the display phase (in which users display the results of their search), and phases in which users make errors, ask the system for help or assistance, and take other actions. An empirical investigation of patterns of use of a university Web-based library catalog was conducted for 479 days. During that period, the characteristics of about 2.5 million sessions were recorded and analyzed, and usage trends were identified. Of the total, 62% of the sessions were for users who performed a search, 27% were from spiders, and 11% were for tourists. During the study period, the average search session lasted about 5 minutes when the study began and had increased to about 10 minutes 16 months later. An average search consisted of about 1.5 presearch actions lasting about 25 seconds, about 5.3 display actions, and 2.5 searches per session. The latter two categories are in the range of 35-37 seconds per session each. There were major differences in usage (number of searches, search time, number of display actions, and display time), depending upon the database accessed
