Military Yearbooks, 1900-2011
This is an indexed collection of Training Schools and Unit Books from across the United States.
Military Yearbooks are one of those home sources, usually found in an attic or basement, which many people don't think of as a family history source. While yearbooks may not provide information about the vital events that are usually associated with genealogical research, they do provide other information about individuals' lives. This information helps place people in historical context as well as provides detail that helps turn individuals, sometimes only known by names and dates, into actual people.
