- 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

- 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
