    Abstract
    The disintermediation that will inevitably result from the increased electronic publication of specialized scholarly information affords an excellent opportunity for one of the traditional intermediaries (e.g., libraries, publishers) to assume responsibilities previously held by other intermediaries. Members of the academy should use this opportunity to take back the responsibility for a significant portion of the specialized scholarly publishing that has, in the traditional environment, been placed in the hands of external publishers. The most imposing impediment to such a reappropriation by the academy derives from the inability of institutions to cooperate with each other. If new attitudes could be created within the academy to circumvent that obstruction, then an academy-based process of scholarly information exchange would finally be feasible. One effective model for such a new form of scholarly publishing would be to establish separate domains, or designated channels, for individual disciplines.

    Abstract
    Developments in information technology have led to changes in the mode of delivery of library services, and in the perceptions of the role of librarians in the information-seeking context. In particular, the proliferation of electronic resources has led to the emergence of new service paradigms and new roles for librarians. The Gateway Library at Penn State University (PSU) is an electronic library in transition, with new technology-based services evolving to address the ever growing and changing needs of the academic community. It facilitates access to and navigation of electronic resources in an integrated technology environment.

    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
    The information seeking behavior of academic scientists is being transformed by the availability of electronic resources for searching, retrieving, and reading scholarly materials. A census survey was conducted of academic science researchers at the University of North Carolina at Chapel Hill to capture their current information seeking behavior. Nine hundred two subjects (26%) completed responses to a 15-minute Web-based survey. The survey questions were designed to quantify the transition to electronic communications and how this affects different aspects of information seeking. Significant changes in information seeking behavior were found, including increased reliance on web based resources, fewer visits to the library, and almost entirely electronic communication of information. The results can guide libraries and other information service organizations as they adapt to meet the needs of today's information searchers. Simple descriptive statistics are reported for the individual questions. Additionally, analysis of results is broken out by basic science and medical science departments. The survey tool and protocol used in this study have been adopted for use in a nationwide survey of the information seeking behavior of academic scientists.

    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
    The journal subscription data of the Central Library (CL) at the Indian Institute of Technology (IIT), Kharagpur during 1995-97 is analysed to assess the prevalent information drought experienced by researchers in less developed countries. The rationale of the study, some of the myths about electronic alternatives over print media, etc. are explained. A study conducted in 1995 at the CL by gathering subscription details from other IITs to explore the options of resource sharing is extracted to present the duplication rates of costly journals. Quantification of research publications from the IIT, Kaharagpur and India are also attempted using electronic databases like CCOD and INSPEC. The budgeting pattern of CL is presented from the IIT's Annual Report. Some possible suggestions to get over the information drought are also explored.

    Abstract
    This two-part article establishes a model of the mediating factors that influence student information behavior concerning electronic or digital information sources that support their learning. The first part reviews the literature that underpinned the development of the research methodology for the Joint Information Systems Committee (JISC) User Behavior Monitoring and Evaluation Framework, as well as the literature that has subsequently helped to develop the model over the 5 years the Framework operated in the United Kingdom, in five cycles of research that were adjusted to meet the emerging needs of the JISC at the time. The literature review attempts to synthesize the two main perspectives in the research studies: (a) smallscale studies of student information behavior; and (b) the studies that focus on the quantitative usage of particular electronic information services in universities, often including implications for training and support. As the review indicates, there are gaps in the evidence concerning the browsing and selection strategies of undergraduate students and the interaction of some of the mediating influences on information behavior. The Framework developed a multimethod, qualitative and quantitative methodology for the continued monitoring of user behavior. This article discusses the methods used and the projectmanagement challenges involved, and concludes that at the outset, intended impacts need to be specified carefully, and that funding needs to be committed at that point for a longitudinal study. A research project on information behavior, intended to inform current policymaking on infrastructure provision, is inherently difficult as behavior changes lag behind provision.

    Abstract
    The proliferation of digital information resources and electronic databases challenges libraries and demands that libraries develop new mechanisms to facilitate and better inform user selection of electronic databases and search tools. We developed a prototype, Web-based database selection expert system based on reference librarian's database selection strategy. This system allows users to simultaneously search all databases available to identify databases most relevant to their quests using free-text keywords or phrases taken directly from their research topics. This article reports on (1) the initial usability test and evaluation of the Selector-the test design, methodology used, performance results; (2) summary of search query analyses; (3) user satisfaction measures; (4) the use of the findings for further modification of the Selector; and (5) the findings of using randomly selected subjects to perform a usability test with predefined searching scenarios. Future prospects of this research have also been discussed in the article.

    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
    Finally Belefant-Miller and King analyze the demographic portion of a survey of faculty and staff at the University of Tennessee to determine reading and information use behavior. Faculty each read an average 384 documents per year for their work including an average 161 journal articles. They funded 84% of their own subscriptions, and averaged 4.2 subscriptions per person. Personal computer access was available to 91.5% and 95% made some use of it. About half access e-mail more than once a day spending an average 24 minutes a day. Browsing remains a very important means of document discovery despite the use of universal bibliographic databases. Paper remains the preferred reading interface, with electronic reading about one quarter of paper readings. Self reported publication rates were 3 journal articles per year.

    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
    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
    The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers (a collaboration dubbed URANIA), has developed a distributed online digital library which has become the dominant means by which astronomers search, access, and read their technical literature. Digital libraries permit the easy accumulation of a new type of bibliometric measure: the number of electronic accesses ("reads") of individual articles. By combining data from the text, citation, and reference databases with data from the ADS readership logs we have been able to create second-order bibliometric operators, a customizable class of collaborative filters that permits substantially improved accuracy in literature queries. Using the ADS usage logs along with membership statistics from the International Astronomical Union and data an the population and gross domestic product (GDP), we have developed an accurate model for worldwide basic research where the number of scientists in a country is proportional to the GDP of that country, and the amount of basic research done by a country is proportional to the number of scientists in that country times that country's per capita GDP. We introduce the concept of utility time to measure the impact of the ADS/ URANIA and the electronic astronomical library an astronomical research. We find that in 2002 it amounted to the equivalent of 736 full-time researchers, or $250 million, or the astronomical research done in France.

    Abstract
    Informal groups of professional workers are forming online communities to create and share information with each other. This paper offers an analysis of an online community of news reporters. Through participant observation in the group electronic discussion, and analysis of archival copies of the group conversation, the authors explore the ways in which this group requests and offers assistance to each other. The types of information created are examined and the temporal characteristics of the group are explored. The analysis revealed a vibrant online community of professionals who use the online communication medium to compliment professional face to face meetings and other forms of communication such as newsletters and journals.

    Abstract
    Purpose - The purpose of this paper is to provide an evaluation of the existing state of practice in knowledge sharing in university libraries. Design/methodology/approach - This is survey research which is based on an electronic questionnaire. Findings - Results reveal that the majority of libraries investigated are quite friendly towards knowledge sharing, and the majority of librarians value the importance of knowledge sharing. Results also confirm that the knowledge that they mostly use is mainly intangible knowledge. Originality/value - If knowledge-sharing requirements of librarians while collaboratively performing reference and information services can be acknowledged, guidelines for enhancing conceptual collaborative process would be suggested.

    Abstract
    This study explores computer scientists' modes of communication within scientific inquiry. Situated in a socially constructed research practice, the findings provide a focused view of the collective use of two sets of communication mechanisms - electronic information mechanisms and interpersonal communication channels - within a technology-intensive field. These results are theoretically and pragmatically interesting for both scholarly communication research and library and information professionals. They suggest that to understand scholarly communication, exploring social cues embedded in the real world practice will yield valuable information, while the detailed examination of research practice may provide a resource for the general design of systems to support collaborative scientific work.

    Abstract
    Let us start with a simple scenario: a man asks a woman "how high is Mount Everest?" The woman replies "29,029 feet." Nothing could be simpler. Now let us suppose that rather than standing in a room, or sitting on a bus, the man is at his desk and the woman is 300 miles away with the conversation taking place using e-mail. Still simple? Certainly--it happens every day. So why all the bother about digital (virtual, electronic, chat, etc.) reference? If the man is a pilot flying over Mount Everest, the answer matters. If you are a lawyer going to court, the identity of the woman is very important. Also, if you ever want to find the answer again, how that transaction took place matters a lot. Digital reference is a deceptively simple concept on its face: "the incorporation of human expertise into the information system." This lecture seeks to explore the question of how human expertise is incorporated into a variety of information systems, from libraries, to digital libraries, to information retrieval engines, to knowledge bases. What we learn through this endeavor, begun primarily in the library context, is that the models, methods, standards, and experiments in digital reference have wide applicability. We also catch a glimpse of an unfolding future in which ubiquitous computing makes the identification, interaction, and capture of expertise increasingly important. It is a future that is much more complex than we had anticipated. It is a future in which documents and artifacts are less important than the contexts of their creation and use.
