The RG 263 CIA Published Maps (also called the CIA Numbered Maps or Numerical Series) is made up of over 22 000 declassified maps. These maps date primarily from the 1940s to the 1970s, cover most areas of the world, and provide a particularly interesting glimpse into the activities and interests of the CIA and US government during the Cold War and Vietnam War. Nearly 3 000 are now available to view and download in the National Archives Catalog.
