Time magazine has recently posted a NIST photo collection about 9/11 (here) and German researchers from the University of Mainz have conducted a minute-by-minute study of emotions during September 11 as the attack and tragedy unfolded, based on a study of text messages (here). These sources were available on Wikileaks (here). Speculations on the Wikileaks source are at reddit.com here.
