    Abstract
    Reports preliminary results from a study, conducted at Rutgers Univ., School of Communication, Information and Library Studies, to conduct observations and experiments under real-life conditions on the nature, effects and patterns in the discourse between users and intermediary searchers and in the related computer commands in the context of online searching and responses. The study involved videotaping interactions between users and intermediaries and recording the search logs for 40 questions. Users judged the relevance of output and completed a number of other measures. Data is analysed both quantitatively, using standard and innovative statistical techniques, and qualitatively, through a grounded theory approach using microanalytic and observational methods

    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
