Definition: NAIL is the on-line information system for the National Archives and Records Administration. Currently, NAIL contains more than 3,000 microfilm publications descriptions, 400,446 archival holdings descriptions, and 124,000 digital copies, but it still represents only a limited portion of NARA's vast holdings. Genealogists will be especially interested in the census, immigration, military and Native American information.
