Resources on the Manhattan Project

The Department of Energy has undertaken a new effort to publish information and documents concerning the Manhattan Project to develop the first atomic bomb. The effort will notably include "the entire thirty-six volume Manhattan District History. Many of the volumes have been declassified" and are now online. "The remaining classified volumes are being declassified with redactions, i.e., still classified terms, phrases, sentences, and paragraphs are removed and the remaining unclassified parts made available to the public. The volumes will be posted incrementally as review and processing is completed."
