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, making it the Library’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.

Ground One: Voices from Post-911 Chinatown: Presenting more than two dozen oral history interviews with Chinese Americans (available in both Chinese and English), this site explores how the events of September 11, 2001 indelibly changed one Manhattan neighborhood. The site was created collaboratively by ASHP/CML, the Museum of the Chinese in the Americas, the Columbia University Oral History Research Office, and New York University’s Asian/Pacific/American Institute, with support from the Rockefeller Foundation
