This impressive bibliography has been compiled by Kevin D. Motes (US Government Information Division, Oklahoma Department of Libraries). It focuses on the US federal documents on terrorism and most specifically on attacks on the World Trade Center and the Pentagon. All documents are described with concise annotations and available through the Federal Depository system. Many, if not most, of these publications are available via the Web. The materials are arranged alphabetically by title within each of the seven sections (Aftermath, Congressional and Presidential Actions, Global Terrorism, International Politics, National Security, US Foreign Relations, and Weapons of Mass Destruction). One might hope for a comprehensive index perhaps in a future edition, but that is a relatively modest quibble. Anyone even moderately interested in the US response to terrorism will definitely find enough to keep himself/herself busy for a long, long time.
