The following is quotes from the notes of this first slide, as presented to OSS '02:
“Although it follows logically from much that is found in the first book (ON INTELLIGENCE: Spies and Secrecy in an Open World), I want to give credeit to Berto Jongman and the PIOOM project. It was his map that brought it all together for me, and it is his map that I recognize today as the finest open source intelligence document in the world.”
