(CNN)Here's a look at what you need to know about the 9/11 Commission, whose report was released on July 22, 2004.

Facts:
The Commission was created to provide a "complete account of the circumstances surrounding the September 11, 2001 terrorist attacks."

The official name of the 9/11 Commission is the National Commission on Terrorist Attacks Upon the United States.

The 570-page, 14-chapter report concluded that a "failure of imagination" kept U.S. officials from understanding the al Qaeda threat before the attacks on New York and Washington.

The report included 41 recommendations for reforming U.S. security agencies to fight terrorism.

The report called for a single national intelligence chief and a single counterterrorism center modeled on the military's unified commands. It also proposed the creation of a single, joint congressional committee to oversee homeland security.

The purpose of the commission was to investigate U.S. counterterrorism policy from August 1998 to September 11, 2001.

Budget for the Commission totaled $15 million.

It originally had 18 months to report, or no later than May 27, 2004, but Congress and the President extended the reporting deadline by two months, to July 26, 2004.

The Commission had nearly 80 full-time employees, contractors and employees on staff.

President George W. Bush and Vice President Dick Cheney agreed to meet with commission chair and vice chair only.

Commission said it had access to all documents and interviews it requested.

"We've gotten everything we've asked for, but always after a lot of resistance and criticism," said member Slade Gorton.

It issued three subpoenas for information, but these were resolved without litigation. The subpoenas went to the Federal Aviation Administration (FAA), the Department of Defense and the City of New York.

The Commission reviewed more than two million pages of documents.
