Free Online Genealogy Website of the Day – National Archives – Archival Databases

This section of the Archives databases is just a small fraction of what the Archives hold, it is an important subset that is very useful for genealogy researchers.

From the Archives website: “You 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. NARA has selected less than 1% of the data files in its holdings 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. AAD provides:

  • Access to over 247 million historic electronic records created by more than 40 agencies of the US federal government and from collections of donated historical materials.
  • Both free-text and fielded searching options.
  • The ability to retrieve, print, and download records with the specific information that you seek.
  • Information to help you find and understand the records.”

Below is a list with links to the various AAD databases.
