    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
    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

    Abstract
    Information seeking and provision does not occur in a vacuum, but is shaped and affected by the way that individuals convey regard for themselves and for each other. Reports 2 studies that explore the intersection between professional and personal or relational dimensions of intermediary practice during the research phase of a set of online computer search interactions that aim to address user information queries. The 1st study examines and compares, through an interpretative microanalytic approach, explicit and implicit situation defining assumptions contained in the initial talk, or opening moves, of 4 intermediaries in interaction with 2 users each. The 2nd study seeks to verify, quantitatively, interpretative claims developed in the 1st study through an analysis of intermediaries' use of pronouns in the course of their interactions with users. The specific patterns of results gained through this quantitiative study were consistent with those achieved interpretatively in the 1st study. The results of these studies are discussed within a proposed theoretic framework developed from the perspective of a constitutive theory of communication
