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
