Forty years after they were famously leaked by Daniel Ellsberg in 1971, the Pentagon Papers will be officially released next month at the Richard Nixon Presidential Library.

The National Archives announced this week that it “has identified, inventoried, and prepared for public access the Vietnam Task Force study, United States-Vietnam Relations 1945-1967, informally known as ‘the Pentagon Papers’.” As a result, 3.7 cubic feet of previously restricted textual materials will be made officially available at the Nixon Library on June 13, the Archives said in a May 10 Federal Register notice.

While any release of historical records is welcome, the official “disclosure” of the Pentagon Papers is in fact a sign of disarray in the government secrecy system. The fact that portions of the half-century old Papers remained classified until this year is a reminder that classification today is often completely untethered from genuine national security concerns.

On March 28, 2011 the National Declassification Center announced “the great news that the Office of the Secretary of Defense (OSD) has declassified the information of interest to them” in the Papers, clearing the way for next month’s public release.
