No idea what's in it exactly. Description as on 911blogger:
On April 3, 2012, the National Institute of Standards and Technology (NIST) released an additional 17,000+ pages of World Trade Center (WTC) records obtained by them from the Port Authority of New York and New Jersey, the New York City Department of Buildings and Turner Construction. The latest records are part of an ongoing NIST WTC records release. NIST has since advised that more records will follow.
