On September 11, 2001, people around the world reacted to the attacks by using the Internet and digital media. This project is dedicated to the collection, preservation, and presentation of the history of that day and its aftermath. The Archive contains more than 150,000 digital items, including 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.. An unprecedented experiment in digital archival collecting, The September 11 Digital Archive became the Library of Congress‘s first major digital acquisition. The site was produced by ASHP/CML and the Center for History and New Media at George Mason University, with support from the Alfred P. Sloan Foundation.
