Huge Lexicon of Official Secrecy & Transparency

Dr. Susan Maret - who gave The Memory Hole rare documents on chem-bio-rad warfare (which I'm still in the process of scanning and posting) - has recently finished her monumental encyclopedic dictionary of terms relating to official information as used in the past and present by the intelligence community, the military, the White House, federal agencies, etc. At over 300 pages, "On Their Own Terms: A Lexicon With an Emphasis on Information-Related Terms Produced by the US Federal Government" is a key addition to the literature of governmental secrecy.
With around 600 entries and (I would estimate) at least 1,000 references, this should be in the form of an expensive book from a specialized publisher, yet the whole thing is available as a free Acrobat file here.
Everyone should have a copy on their hard drive.
