The broader context in the last twenty years awareness of the information and documentation problems of the social sciences has grown, but almost as if by stealth. During that period there have been significant developments for practice, organization and research in social science information, but knowledge of these has remained largely confined to small groups of specialists closely associated with them. In the main it has been library and information developments in science and technology that have captured the interest and attention of the majority of professionals and specialists as such: for example, the development of computer‐based citation indexes; the introduction of the computer database as a successor to the printed secondary journal; the development of online search facilities and associated software and retrieval techniques; the exploitation of telecommunications and computers to create new information technology, leading to alternative means of interpersonal communication, the possibilities of electronic journals and a vision of the paperless society. This situation is hardly surprising since science and technology provide the productive base for advanced societies.

This paper provides an overview of the range and development of health informatics, with examples from the literature world wide covering the types of information involved, the areas of application, the impact of evidence based medicine and other professional issues, integrated information systems, and the needs of the public, patients and their carers. While medical informatics certainly comprises a major part of health informatics it is not the main focus of this paper. Medical informatics is the older term and involves the use of information technology and computing specifically for medical science research, and the diagnosis and treatment of disease involving, for example, X‐rays, imaging, resonance, and magnetic scanning techniques. Rather, the scope of this review is the literature relating to the wider concept of the management of information through the interdisciplinary application of information science and technology for the benefit of patients, scientists, managers, staff, and carers involved in the whole range of healthcare activity.

Some results of a recent study of the information needs of social scientists are selectively summarised and commented upon. Where relevant, to monitor change, this is set in the context of earlier research, notably during the peak period of the 1970s. This paper is not, however, in any sense intended as a balanced state of the art review of research and system design progress since 1970. Instead, it concentrates on the fresh evidence provided by a small‐scale qualitative study by depth interview amongst social scientists, broadly defined, and intermediaries in the social science area.

This article reviews existing studies of the invisible college phenomenon and considers the implications for information transfer among researchers, particularly within the social sciences. The likely impact of developments in communications technology on interpersonal networks is discussed and a number of areas for further investigation proposed.

I would like to discuss the implications of recent NHS reforms for the provision and use of information in healthcare—particularly in the National Health Service.

A behavioural approach to information retrieval system design is outlined based on the derivation of a behavioural model of the information seeking patterns of academic social scientists. The information seeking patterns of a variety of academic social scientists were broken down into six characteristics: starting, chaining, browsing, differentiating, monitoring, and extracting. These characteristics constitute the principal generic features of the different individual patterns, and together provide a flexible behavioural model for information retrieval system design. The extent to which these characteristics are available on existing systems is considered, and the requirements for implementing the features on an experimental system are set out.
