will ultimately contain about 200,000 documents. Some of these sources were formerly classified, but all are now unclassified (4). DOE/NVOO is responsible for data collection. One of its contractors, History Associates Incorporated (HAI), is collecting pertinent information under the direction of the Historian’s Office, DOE Headquarters. The effort initially focused on sources concerned with offsite radioactive fallout from U.S. nuclear weapons testing. It was later broadened to include documents relevant to onsite as well as offsite fallout, oceanic as well as continental nuclear testing, and military as well as civilian participation in the tests (5). HAI has reviewed and sent to CIC selections from some major collections, including materials from DOE Headquarters and the Los Alamos National Laboratory (LANL). The collection at DOE Headquarters provided minutes from meetings of the AEC, the General Advisory Committee established by AEC to advise on the testing, and the AEC/Military Liaison Committee, as well as staff papers and records of the Division of Military Application and the Division of Biology and Medicine. The LANL archives made documents available concerning the Test Organization, which was responsible for conducting a number of the nuclear test series; scientific studies performed as part of the tests; and fallout resulting from the detonations. In addition, some signif- icant collections were located at such sites as the Navy Bureau of Ships, the Naval Radiological Defense Laboratory, and the Oak Ridge Center for Atomic Research (5). The DOE/NVOO Coordination and Information Center is a valuable public resource on atmospheric nuclear weapons testing. A substantial number of the documents have been selected by professional historians according to established screening criteria, some of which are highlighted in figure 3. These researchers have identified the materials by location, collection, and folder title. Such identifiers make it possible to trace the documentation to its original source (53; 6). Appendix D.2 provides further information on the scope of the CIC collection and on facility policies and procedures. 34
