National Archives Archival DatabasesYou will find in the Access to Archival Databases (AAD) resource online access to records in a small selection of historic databases preserved permanently in NARA. Out of the nearly 200,000 data files in its holdings, NARA has selected approximately 475 of them for public searching through AAD. We selected these data because the records identify specific persons, geographic areas, organizations, and dates. The records cover a wide variety of civilian and military functions and have many genealogical, social, political, and economic research uses
