September 11th Sourcebooks index (NSArchive volumes I–VII and updates)

Observation

The National Security Archive organised a September 11th Sourcebook series of at least seven volumes plus later FOIA postings on Clarke, FAA, and NTSB transcripts.

Interpretation

An index of declassified files. Weight lives in the documents, not the index.

OBSERVATION (nsarchive2.gwu.edu/NSAEBB/sept11/index.html, 3 Sep 2026).

Volume I Terrorism and U.S. Policy
Volume II Afghanistan: Lessons from the Last War
Volume III BIOWAR (Nixon-era BW termination — contextual, not 2001)
Volume IV King Zahir files 1970–73 — contextual
Volume V Anthrax at Sverdlovsk 1979 — contextual
Volume VI The Hunt for Bin Laden (Special Forces role)
Volume VII The Taliban File, plus Parts II–IV and updates (Pakistan arms; Omar 1998 call; pre-9/11 expulsion attempts)

Later index entries on the same page: Bush administration's first memo on al-Qaeda (Clarke); 9/11 Commission staff report on FAA failings; FAA believed second 9/11 plane heading towards NY for emergency landing; Government releases detailed information on 9/11 crashes / complete air-ground transcripts.

Archive mission statement on the page: put primary-source documentation on the record after the attacks.

Volumes III–V are background, not 11 September observations. They stay catalogued so the Sourcebooks are not silently trimmed.
