Published for the tenth anniversary of 9/11, this new edition of the authorized report is limited to the Commission’s riveting account—which was a finalist for the National Book Award—of the attack and its background, examining both the attackers and the U.S. government, the emergency response, and the immediate aftermath. It includes new material from Philip Zelikow, the Commission’s executive director, on the Commission’s work, the fate of its recommendations, and the way this struggle has evolved right up to the present day.
