Introductory remarksThe conversations took place during the course of research into pharmacetical information exchange with developing countries. They wandered into the territory of the principles of information science (IS) because it was difficult to determine boundaries.Where did IS begin? Where did other disciplines end? The chats proved to be fruitful because, firstly, pharmaceutical information is a well-worked area offering plenty of examples and, secondly, information issues in the developing world are not masked by sophistication. This is not to say that the developed countries are beyond the basics -far from it -but they have been content, by and large, to apply IS as a successful and lucrative technology. Had the discipline evolved in the direction of pure rather than an applied science, the emergent philosophy and research methodology may well have taken a very different form. The resultant exploration of these ideas could be significant and is certainly worth recording.
Underlying preceptsThere are few, if any, laws pertaining to IS; one or two postulates in bibliometrics maybe, but not much else. The reason is not hard to see -with its roots on *The author is retired, but associated with 171 477 8584 the one hand in librarianship and on the other in the service of science and technology, the fundamental nature of IS has tended to be overlooked. It is, in fact, the study of the knowledge system; the nature of knowledge and the way in which it is acquired and imparted. it is about the contact between one mind and another, and the interrelationships between information and human attitudes and behaviour -which are profound. In view of the self-evident importance of all of these attributes, it is astonishing that practising information scientists have committed such little effort to formalising the principles involved. Admittedly, the issues are complicated by a certain looseness of terminology, since most IS terms are also in ordinary everyday use. For instance, knowledge, information, intelligence and communication have overlapping meanings in common parlance. It would become essential, therefore, to establish term definitions and specify meanings more precisely if it were desired to introduce greater rigour into the subject discipline.In what follows, the idea that information and action are inextricably linked is a major theme; knowledge for knowledge's sake has no place in this interpretation, except perhaps in the most esoteric of human activities. We generally impart knowledge (i.e. we inform) in order to influence the current or future actions of others, and we ourselves acquire knowledge (i.e. are informed) in order to form attitudes and act.
