Hands Down Best Reference on Topic
Britt published several key articles on this topic that appear to have been brought together in a book and I am very, very pleased that his work is now in book form, This will be “Ref A” for some time to come. If you have doubts, look up the articles, but I strongly recommend the book as a collector's item and a single edited paginated reference.
I also reocmmend the Harvard book,, a collection of memoranda, “Confrontation or Collaboration? Congress and the Intelligence Community.”
The work of Al Cummin, himself former Staff Director of the Senate Select Committee on Intelligence, is also recommended, he writes on intelligence issues as a senior executive author for the Congressional Research Service.
