Over a 12-month period concluding in July 2014, DOE released to the public the Manhattan District History, a multi-volume classified history of the Manhattan Project.  Commissioned in late 1944 by General Leslie Groves, the history was “intended to describe, in simple terms, easily understood by the average reader, just what the Manhattan District did, and how, when, and where.”  The history records the Manhattan Project’s activities and achievements in research, design, construction, operation, and administration, assembling a vast amount of information in a systematic, readily available form.

OpenNet gets a new look!


OpenNet gets a new look!

The newly redesigned OpenNet contains spotlights on declassified collections. This quarter the spotlight is on the Human Radiation Experiments collection. OpenNet provides easy, timely access to the Department of Energy’s declassified documents, including information declassified in response to Freedom of Information Act requests. In addition to these documents, OpenNet references older document collections from several DOE sources. This database is updated regularly as more information becomes available. The OpenNet web site is sponsored by the Office of Health, Safety and Security Office of Classification. OpenNet is intended to make information that is no longer classified more readily available to the public. This action supports DOE’s Open Government Initiative.  Through OpenNet you can find more information on openness policy and openness initiative information resources.
