From Secrecy News:
OPERATION DARK HEART: THE AFTERMATH
The Pentagon's heavy-handed attempt to censor the new Afghanistan war memoir "Operation Dark Heart" by Anthony Shaffer has predictably turned a volume of narrow, specialized interest into a mainstream bestseller.
It has also focused attention on just what information the government was seeking to conceal, and why. For a review of the material that was blacked out in the second edition of the book, see "Censored book masks sensitive operations" by Sean D. Naylor, Army Times, October 4. A side-by-side view of the book's Index, in censored and uncensored formats, is here (pdf).
