The exhibition, titled "Remembering 9/11," will present a selection of several hundred photographs taken by professional and amateur photographers in the immediate aftermath of the attacks on the World Trade Center.
Officials say the exhibit will also include letters written to police officers and firefighters, objects that were placed at makeshift shrines around New York, and drawings of the National September 11 Memorial.
One month after the attacks, the society started a series of exhibitions, public events and education initiatives called "History Responds." Since then, more than 150,000 visitors have taken part in its programs.
The exhibit will open Sept. 8 and remain on view through April 1, 2012.
