There has been a flare-up in interest in science policy and a key factor in this is the increased interest in analysing the role that research can play in informing policy making. A pioneering venture in this field was Government and Research: The Rothschild Experiment in a Government Department (1983) Heinemann. No other work had penetrated the deepest recesses of government to observe at first hand the attempts of a major department to determine its research agenda through collaboration with leading scientists in a wide range of fields, to observe how research was commissioned, and then evaluated by scientific teams, and how it began to enter the policy blood streams of the departments. This revised and augmented version updates the original text for current policy concerns and takes account of changes in science policy studies, whilst preserving its essential themes. It contains a succinct account of where matters now stand as well as an extended analysis of the themes that continue to dominate research and science policy.
