Volume 59, No.2 of Studies in Intelligence arrived in today’s mail but more importantly, and unusually, it is already ‘up’ on the CIA website in .pdf format: https://www.cia.gov/library/center-for-the-study-of-intelligence/csi-publications/csi-studies/studies/vol-59-no-2/index.html

It contains a very good article by Michael Goodman on the development of the UK-US relationship as it relates to the sharing of intel – UKUSA Agreement, etc. Related NSA documents may be accessed at: https://www.nsa.gov/public_info/declass/ukusa.shtml
