One of the most useful and easily accessible guides to primary sources relating to Austrian, Hungarian, and Austro- German history for the years 1933–1945 available in the United States is the continuing multivolume series prepared under the direction of the Committee for the Study of War Documents of the American Historical Association entitled Guides to German Records microfilmed at Alexandria, Va. (Washington, D. C.: The National Archives, National Archives and Records Service, General Services Administration, 1958-). In the past a person using this series has had to go through all the volumes page by page. This article is intended to provide a working guide to this widely scattered material, much of which has remained buried amid a mass of other data. The listings which follow are suggestive rather than exhaustive. Although the annotations are concentrated on what the authors believe are the more immediately valuable materials in each category, every page cited contains documents related to the general historical area in each section. Our breakdown is divided into the following five sections: (1) economic history, (2) military history, (3) Nazi administration and repression, (4) political history, and (5) miscellaneous materials.
