Do you have ancestors who served in the U.S. Army? Yes? Then you really should take a look at the website of the Army Heritage and Education Center (AHEC). The U.S. Army Military History Institute branch of the AHEC includes much material of interest to genealogists:
“- The U.S. Army Military History Institute (USAMHI) is an institute of the U.S. Army Heritage and Education Center.
- Our mission is to preserve the Army's history and ensure access to historical research materials. We serve as the primary facility where researchers study Army history.
- USAMHI holdings include books, manuscripts, photos, and maps.
- Both official and unofficial (or public) patrons are welcome. We give highest priority to Army users. There is no fee to enter the Institute. A fee-for-service is charged for providing copies of holdings to unofficial patrons.”
