The 9/11 Commission Report, formally named Final Report of the National Commission on Terrorist Attacks Upon the United States, is the official report of the events leading up to the September 11, 2001 attacks. It was prepared by the National Commission on Terrorist Attacks Upon the United States (informally sometimes known as the "9/11 Commission" or the "Kean/Hamilton Commission") at the request of the President and Congress, and is available to the public for sale or free download.

The 9/11 Commission Report was released to the Public Domain(follow @thepublicdomain if interested in this topic) and available as a PDF, on scribd (flash & HTML5), LibreVox audio and an XHTML version amongst many other formats.

The 9/11 Report: A Graphic Adaptation by Sid Jacobson and Ernie Colón, and published by Hill & Wang, is an abridged graphic novel adaptation of the report (although a copyrighted work).

This evening I listened in to the RSA Event - The Public Domain: enclosing the commons of the mind delivered by Professor James Boyle. In his new book The Public Domain, Professor James Boyle describes how our culture, science and economic welfare all depend on the delicate balance between those ideas that are controlled and those that are free, between intellectual property and the public domain —the realm of material that everyone is free to use and share without permission or fee.
