From Slate.com:
Wikileaks released a searchable database of over 1.7 million diplomatic cables from the years 1973 to 1976 today. Because so many of them — over 200,000 — are connected to former U.S. Secretary of State Henry Kissinger, the collection is being informally dubbed the "Kissinger Cables." But unlike previous Wikileaks document collections, this release isn't a whistleblower leak. Instead, it's the result of an effort to obtain and organize public documents obtained from the National Archives and Record Administration.
So, what's in them? The findings, so far, are more interesting than they are damning. In that light, the "Kissinger Cables," officially called "PlusD," seem most notable as a well-organized, historical archive of the scope, tone, and depth of U.S. diplomacy around the world. The new collection, which does not include Top Secret cables, is searchable with Wikileaks's 2010 "Cablegate" release.

—Kissinger didn't like the Freedom of Information Act: In a transcript of a conversation, Kissinger joked, "Before the Freedom of Information Act, I used to say at meetings, 'The illegal we do immediately; the unconstitutional takes a little longer.' [laughter] But since the Freedom of Information Act, I'm afraid to say things like that."
