Books by Gregory F. Treverton

This report identifies lessons learned from looking at the use of internal collaborative tools across the Intelligence Community, especially across the four biggest agencies: Central Intelligence Agency, Defense Intelligence Agency, National Security Agency, and National Geospatial Intelligence Agency.

During the Cold War, U.S. intelligence was concerned primarily with states; non-state actors like terrorists were secondary. Now the priorities are reversed and the challenge is enormous. States had an address, and they were hierarchical and bureaucratic. They thus came with some 'story'. Terrorists do not. States were 'over there', but terrorists are there and here. They thus put pressure on intelligence at home, not just abroad. The strength of this book is that it underscores the extent of the change and ranges broadly across data collection and analysis, foreign and domestic, as well as presenting the issues of value that arise as new targets require collecting more information at home.
