The first historical study of export control regulations as a tool for the sharing and withholding of knowledge.

In this groundbreaking book, Mario Daniels and John Krige set out to show the enormous political relevance that export control regulations have had for American debates about national security, foreign policy, and trade policy since 1945. Indeed, they argue that from the 1940s to today the issue of how to control the transnational movement of information has been central to the thinking and actions of the guardians of the American national security state. The expansion of control over knowledge and know-how is apparent from the increasingly systematic inclusion of universities and research institutions into a system that in the 1950s and 1960s mainly targeted business activities. As this book vividly reveals, classification was not the only--and not even the most important--regulatory instrument that came into being in the postwar era.
