From the Gov Archives:
The 24 million World War I Draft Registration Cards in the custody of the National Archives Southeast Region provide an invaluable resource for academic researchers and genealogists. All males in the United States, born between the years 1872 and 1900, were required by law to register for the draft throughout 1917 and 1918. This series of records includes cards from all 50 states and Puerto Rico. The answers provided to the questions on the cards typically reveal details about where a man lived, his occupation, race, immigration status, and in many cases his place of origin and nearest relative. The following selection presents a unique snapshot of what is available in this extensive collection.
