When the full Pentagon Papers were released on June 13, 2011, the U.S. government had attempted to keep under wraps 11 words on one particular page. Interestingly, these specific words had been in the public domain since the House Armed Services Committee published the government edition of the Papers in 1972. Recently, the folks at the National Security Archives at George Washington University decided to offer up 11 possibilities for the identity of these mysterious excised words. Released in July 2011, this electronic briefing book contains the eleven documents, complete with a bit of historical background and contextual material. The briefing book contains texts that detail covert attacks on North Vietnam, an action against Cambodia, and a CIA bombing in North Vietnam. Rather fascinating material here, and as with the other publications, the National Security Archives has done a fine job.
