    Abstract
    ADEPT is a 5-year project whose goals are to develop, deploy, and evaluate inquiry learning capabilities for the Alexandria Digital Library, an extant digital library of primary sources in geography. We interviewed nine geography faculty members who teach undergraduate courses about their information seeking for research and teaching and their use of information resources in teaching. These data were supplemented by interviews with four faculty members from another ADEPT study about the nature of knowledge in geography. Among our key findings are that geography faculty are more likely to encounter useful teaching resources while seeking research resources than vice versa, although the influence goes in both directions. Their greatest information needs are for research data, maps, and images. They desire better searching by concept or theme, in addition to searching by location and place name. They make extensive use of their own research resources in their teaching. Among the implications for functionality and architecture of geographic digital libraries for educational use are that personal digital libraries are essential, because individual faculty members have personalized approaches to selecting, collecting, and organizing teaching resources. Digital library services for research and teaching should include the ability to import content from common office software and to store content in standard formats that can be exported to other applications. Digital library services can facilitate sharing among faculty but cannot overcome barriers such as intellectual property rights, access to proprietary research data, or the desire of individuals to maintain control over their own resources. Faculty use of primary and secondary resources needs to be better understood if we are to design successful digital libraries for research and teaching.

    Abstract
    Faculty members from a major university were surveyed to explore the possible relationship between Internet usage and the following dependent variables: computer usage (length of time and perceived expertise), length of time of Internet use, perceived expertise of Internet use, and perceived utility of the Internet. 97% have an Internet account. Furthermore, computer literacy and length of computer experience are correlated with early adoption of the Internet, perceived utility of the Internet is correlated with computer literacy and with Internet usage, and usage is correlated with perceived expertise, but not with the length of time of Internet experience. Highly skilled computer users are more likely to use the network in a more intensive way and have higher appreciation of the network's potential

    Abstract
    This study aimed to determine if the searching behaviour of remote users of LIAS, Penn State's online catalogue differed from those using the OPAC within the library. More than 1.000 searches done by remote users (those accessing the system via either dial-access or the university's computer network) were compared to more than 1.000 searches done by in-house users. Each search was duplicated step by step and analysed according to a pre-determined set of criteria. Although few dramatic differences were found between the 2 groups, there were enough subtle differences to generate interest. In general, remote users are the more sophisticated searchers, bearing out the assumption that remote users seem to have a better conceptual knowledge of how an information system should operate. On the other hand, they struggle more with the procedural details of how to use the OPAC. Dial-access users seem to constitute a unique group of users: their searches are often quite different than those done by either network or in-house users

    Abstract
    Over the last 4 years, the Information Interaction Laboratory at Rutgers' School of communication, Information and Library Studies has performed a series of investigations concerned with various aspects of people's interactions with advanced information retrieval (IR) systems. We have benn especially concerned with understanding not just what people do, and why, and with what effect, but also with what they would like to do, and how they attempt to accomplish it, and with what difficulties. These investigations have led to some quite interesting conclusions about the nature and structure of people's interactions with information, about support for cooperative human-computer interaction in query reformulation, and about the value of visualization of search results for supporting various forms of interaction with information. In this discussion, I give an overview of the research program and its projects, present representative results from the projects, and discuss some implications of these results for support of subject searching in information retrieval systems

    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
    User persistence in displaying postings is a significant human factor in the design of computer driven information systems, including online catalogs. Expert opinion and a study of users of a first generation online catalogue have suggested that users normally display no more than 30 to 35 postings. A follow up study on a second generation system with a larger database found that a greater proportion of users reported overload, but 100 postings (rather than 15) were considered 'too many'. Partially persistent users typically displayed 28 postings, but overloaded uses did not outnumber totally persistent users until postings retrieved exceeded 200. The findings suggest that, given sufficient resources, designers should still consider 30 to 35 postings typical persistence, but also justify treating 100 or 200 postings as a common threshold of overload

    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
    Reports of a study in a Chilean university library, comparing 100 users of online databases and CD-ROMs with 100 users of non-computerized bibliographical resources. Results showed that users tended to be teachers / researchers, and potential users were postgraduate students. Comparison of search results showed online searching improved results and saved time. The chief reasons for non-use were ignorance of the service and use of own personal computer. The study indicated the need to review policy on database acquisition and improve promotion of the service. In general, librarians should motivate greater use of online searching by providing skilled intermediary services to maximize uptake

    Abstract
    Report of a study at the University of Montreal (Quebec) analysing research on the behaviour of children using information technology (online databases, CD-ROM, computerised catalogues). From a range of publications covering 6-12 year olds in the US, Canada, Europe and Oceania common features were identified: (1) children's cognitive development does not match the structured approach required for this type of information research, (2) the main abrriers were physical (e.g. using keyboard), intellectual (no capacity for abstract reasoning) and social (little access to computers); (3) in terms of natural skills, boys has greater abilities than girls. Results indicate the need to make technology more appropriate for children, and train libarrians to recognise the real capacities and limitations of children so they can teach them the basic skills

    Abstract
    Reports results of a study to investigate judgements made by searchers of online catalogues by using transaction log analysis to associate online catalogue searchmethods with decisions so as to retrieve location information. The study used the Mainframe Interface to Libraries Online (MILO), an interface to the Illinois Library Computer Systems Office (ILCSO) online union catalogue for the 45 academic libraries belonging to ILCSO. MILO provides access to a bibliographic database and directly links to another database with circulation and location records. As the latter database only provides location and circulation status, searchers' decisions to make links to such data are seen as an indication that the records being linked represent potentially useful material. Via a transaction log analysis, the linked location records were associated wiht the access points used to retrieve them in order to analyze the value and problems of searchers' uses of specific access points. Transaction logs were analyzed for a 38-day sample of the 1994 logs. Counting of records retrieved through the use of multiple access points (making the total greater than 100%), subject fields were used to access over 30%, author fields to access over 19%, and title fields to access over 51% of all records linked to location information. Other fields were used to retrieve very small percentages of linked records

    Abstract
    Presents the selected findings of a research project based on the British Library Network Online Public Access Catalogue (NOPAC) carried out in the department of information and library management at the University of Northumbria in Newcastle, UK over the academic year 1994/95. Data was collected by means of interviews with NOPAC users especially on use made of the NOPAC and on attitudes towards the NOPAC's interface. Discusses the views of users as they relate to: display features; mode of interaction; help/user assistance; extra features available; and usability. Lists important points which emerged from the survey concerning the NOPAC service

    Abstract
    The Web and especially major Web search engines are essential tools in the quest to locate online information for many people. This paper reports results from research that examines characteristics and changes in Web searching from nine studies of five Web search engines based in the US and Europe. We compare interactions occurring between users and Web search engines from the perspectives of session length, query length, query complexity, and content viewed among the Web search engines. The results of our research shows (1) users are viewing fewer result pages, (2) searchers on US-based Web search engines use more query operators than searchers on European-based search engines, (3) there are statistically significant differences in the use of Boolean operators and result pages viewed, and (4) one cannot necessary apply results from studies of one particular Web search engine to another Web search engine. The wide spread use of Web search engines, employment of simple queries, and decreased viewing of result pages may have resulted from algorithmic enhancements by Web search engine companies. We discuss the implications of the findings for the development of Web search engines and design of online content.

    This research draws on longitudinal network data from an online community to examine patterns of users' behavior and social interaction, and infer the processes underpinning dynamics of system use. The online community represents a prototypical example of a complex evolving social network in which connections between users are established over time by online messages. We study the evolution of a variety of properties since the inception of the system, including how users create, reciprocate, and deepen relationships with one another, variations in users' gregariousness and popularity, reachability and typical distances among users, and the degree of local redundancy in the system. Results indicate that the system is a small world characterized by the emergence, in its early stages, of a hub-dominated structure with heterogeneity in users' behavior. We investigate whether hubs are responsible for holding the system together and facilitating information flow, examine first-mover advantages underpinning users' ability to rise to system prominence, and uncover gender differences in users' gregariousness, popularity, and local redundancy. We discuss the implications of the results for research on system use and evolving social networks, and for a host of applications, including information diffusion, communities of practice, and the security and robustness of information systems.

    Abstract
    At the start of the academic year reference staff are hard pressed to provide sufficient assistance to first time users of CD-ROMs, who have missed bibliographic instruction classes, or who need more guidance before searching. The literature on CD-ROMs was reviewed, and a survey conducted to estimate the training needs of searchers. It was found that 100% of the inexperienced searchers required assistance while searching, and 50% of their search strategies were later rated as poor. More than half the experienced searchers also needed the librarians assistance, and 31% of this group demonstrated a poor understanding of searching techniques. The survey findings were incorporated into CDIntro, a computer assisted learning package designed by the authors
