September 11 Digital Archive

"The September 11 Digital Archive uses electronic media to collect, preserve, and present the history of September 11, 2001 and its aftermath. The Archive contains more than 150,000 digital items, a tally that includes more than 40,000 emails and other electronic communications, more than 40,000 first-hand stories, and more than 15,000 digital images. In September 2003, the Library of Congress accepted the Archive into its collections, an event that both ensured the Archive's long-term preservation and marked the library's first major digital acquisition."

I highly encourage you to take a few minutes to browse around the incredible image collection on hand as well as read through some of the documents they have.
