Read the 10 previously unclassified PDB's, from 1965-68, declassified in 1993, at this excellent website, sponsored by The National Security Archive at George Washington University. There's so much interesting info at this site; it's a must-hit!!

The chair of the 9/11 commission, former New Jersey governor Thomas Kean, said that "hese are documents that only two or three people would normally have access to. To make those available to an outside group is something that no other president has done in our history."
Actually, ten President's Daily Briefs are in the public domain, officially declassified by the U.S. government. (Note 4) The CIA established the PDB under that name in 1964, and PDBs from the Johnson administration began to be declassified in 1985, during the tenure of President Reagan. The ten declassified PDBs contain such extraordinarily sensitive items as this one on Egypt: "Nasir, in a speech to the nation on Saturday, outlined a 'program of action' to bring about political reform. We doubt that it will amount to much." That's the whole item. Another supersensitive entry concerns the head of state of Indonesia: "Despite Sukarno's long-standing kidney ailment, for which he delays proper treatment, he has seemed quite chipper lately." Three lines of the item are blacked out since they refer to the sources of intelligence, perhaps Indonesian assets of the CIA, or communications intercepts, or maybe just the British ambassador. One of the PDBs is even published in the latest volume of the distinguished State Department documentary series, Foreign Relations of the United States.
