    Abstract
    In anticipation of the explosive growth of digital libraries, a complex study was undertaken seeking to evaluate 21 diverse services at 5 major academic research libraries. This work stands as a model for evaluation of digital libraries, through its focus on both the costs of operations and the impacts of the services that those operations provide. The data have been analyzed using both statistical methods and methods of Data Envelopment Analysis. The results of the study, which are presented in detail, serve to demonstrate that a cross-functional approach to library services is feasible. They also highlight a new measure of impact, which is a weighted logarithmic combination of the amount of time that users spend interacting with the service, combined with a Likert-scale indication of the value of that service in relation to the time expended. The measure derived, incorporating simple information obtainable from the user, together with information which is readily available in server/client logs, provides an excellent foundation for transferring these measurement principles to the Digital Library environment

    Abstract
    Examines traditional and interactive models in information retrieval, and proposes an interactive information retrieval model based on different levels in the interactive process. Proposes a stratified interactive information retrieval model which has potential to account for a variety of aspects in the processes involved. In this model information retrieval interaction is decomposed into several levels that subtly affect each other. Makes general remarks on the state of information retrieval interaction research

    Abstract
    The purpose of this entry is to provide an overview of information science as a field or discipline, including a historical perspective to illustrate the events and forces that shaped it. Information science is a field of professional practice and scientific inquiry dealing with effective communication of information and information objects, particularly knowledge records, among humans in the context of social, organizational, and individual need for and use of information. Information science emerged in the aftermath of the Second World War, as did a number of other fields, addressing the problem of information explosion and using technology as a solution. Presently, information science deals with the same problems in the Web and digital environments. This entry covers problems addressed by information science, the intellectual structure of the field, and the description of main areas-information retrieval, human information behavior, metric studies, and digital libraries. This entry also includes an account of education related to information science and conclusions about major characteristics.

    Abstract
    Develops a theoretical framework for expressing the nature of feedback as a critical process in interactive information retrieval. Feedback concepts from cybernetics and social sciences perspectives are used to develop a concept of information feedback applicable to information retrieval. Adapts models from human-computer interaction and interactive information retrieval as a framework for studying the manifestations of feedback in information retrieval. Presents results from an empirical study of real-life interactions between users, professional mediators and an information retrieval system computer. Presents data involving 885 feedback loops classified in 5 categories. Presents a connection between the theoretical framework and empirical observations and provides a number of pragmatic and research suggestions

    Abstract
    Discusses underlying concepts related to value that must be clarified in order to proceed with any pragmatic study of value, and establishes a theory of use-oriented value of information and information services. Examines the notion of value in philosophy and economics and in relation to library and information services as well as the connection between value and relevance. Develops 2 models: one related to use of information and the other to use of library and information services. They are a theoretical framework for pragmatic study of value and a guide for the development of a Derived Taxonomy of Value in Using Library and Information Services

    Abstract
    Synthesises the major findings of several decades of research into the magnitude of individual deffirences in information retrieval related tasks and suggests implications for practice and design. The study is related to a series of studies of human aspects and cognitive decision making in information seeking, searching and retrieving

    Abstract
    Information science is best defined as a discipline in terms of the problems it addresses. Its origins date back to the scientific and technical revolution after the 2nd World War, and its development has been essentially characterised by interdisciplinarity. Librarianship, computer science, cognitive science and communication studies all share interests with infomation science, but with increasing emphasis on the information society and the information industry dictated by technological imparatives, information science is now at a critical point in its evolution. The problem it sets out to solve are not decreasing but changing, with the pressure to improve access to an ever increasing store of knowledge. The social need for information science is evident, whatever the name given to the knowledge and skills which it encompasses

    Abstract
    Details with specifics of the study: importance of taxonomy; the method used for gathering data on user assessments of value in 5 research libraries, involving 18 services and 528 interviews with users; development and presentation of the taxonomy; and statistics and tests of the taxonomy. A novel aspect is the division of value of information services into 3 general classes or facets; reasons for use of a service in the given instance; quality of interaction (use) related to that service; and worth, benefits, or implications of subsequent results from use
