    Abstract
    Previous models of searching behavior have taken as their foundation the Markov model of random processes. In this model, the next action that a user takes is determined by a probabilistic rule which is conditioned by the most recent experiences of the user. This model, which has achieved very limited success in describing real data, is at odds with the evidence of introspection in a crucial way. Introspection reveals that when we search we are, more or less, in a state of expectancy, which can be satisfied in a number of ways. In addition, the state can be modified by the accumulated evidence of our searches. The Markov model approach can not readily accommodate such persistence of intention and behavior. The Petri Net model, which has been developed to analyze the interdependencies among events in a communications network, can be adapted to this situation. In this adaptation, the so-called "transitions" of the Petri Net occur only when their necessary pre-conditions have been met. We are able to show that various key abstractions of information finding, such as "document relevance", "a desired number of relevant documents", "discouragement", "exhaustion" and "satisfaction" can all be modeled using the Petri Net framework. Further, we show that this model leads naturally to a new approach to the collection of user data, and to the analysis of transaction logs, by providing a far richer description of the user's present state, without inducing a combinatorial explosion

    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
    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
    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
    The design and implementations of online systems in libraries have proceeded without much demonstrated empirical understanding of the complexities of users' needs. Reports interviews with a group of humanist scholars at the Univ. of Pennsylvania about their experiences with the Research Libraries Information Network (RLIN) database. These interviews yielded a wide range of responses. 4 factors emerged consistently as significant determinants of use: content, connectivity, user-friendliness, and cost. Discusses and evaluates the significance of these factors, individually and in relation to one another

    Abstract
    Describes an investigation of attitudes to the LION (Library Integrated Online Network) online public access catalogue at Liverpool Polytechnic Library (now Liverpool John Moores University) using observation and a questionnaire survey of 55 library users. The reaction to the automation of the library catalogue was positive and it appears to have improved service to users but more user education and guidance would result in a further improvement

    Abstract
    Discusses the importance of catalogue use studies, particularly in the context of database development for networking. A literature review reveals that most of the studies are conducted in western countries which may be grouped in 3 categories: user studies; studies relating to search failures; and experiments with methodology. Stresses the need for more such studies in the context of libraries in India, particularly in the view of library network development in the country

    Abstract
    Reports results of a study to elicit information from the users of the Wisconsin University at Madison online catalogue (Network Library System (NLS)). The General Library System (GLS) conducted focus group interviews with undergraduate students, graduate students, and faculty. Undergraduate students tend to utilize subject searching capabilities. Graduate students and faculty utilize subject searching only as a last resort; they typically search by known author or title. A significant number of the participants reported experience with library online catalogues other than NLS, although the majority of faculty reported very little experience with other online catalogues. All the focus group participants, but particularly the undergraduate students, evidenced confusion between keyword searching and searching controlled vocabulary. Inclusion of circulation status in the bibliographic records was identified as an important feature of the catalogue

    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
    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
    According to many studies, social network sites (SNS) have become some of the most popular online destinations. It has been pointed out that very little is known about the psychosocial variables that predict people's use of these websites. In this article, our general objective is to understand behavioral intentions to use SNS employing the well-known unified theory of acceptance and use of technology (UTAUT), which has been validated in a number of studies. Data were collected through a questionnaire survey from a final sample of 1,039 social networking website users in Africa. We have shown that there are contexts, such as the African context, in which the UTAUT does not hold up. Explanations are provided to support the findings.

    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.
