The full congressional inquiry into the events surrounding Sept. 11^th^, 2001 (well, minus the sections pulled by the White House) is available online.
In February 2002, the Senate Select Committee on Intelligence and the House Permanent Select Committee on Intelligence agreed to conduct a Joint Inquiry into the activities of the U.S. Intelligence Community in connection with the terrorist attacks perpetrated against our nation on September 11, 2001. This report (available as both S. Rept. 107-351 and H. Rept. 107-792) consists of 832 pages that presents the joint inquiry’s findings and conclusions, an accompanying narrative, and a series of recommendations.
(via Lambert, who’d also like to know if there’s an easy way to convert the report to HTML…I’m clueless)
