In 1940, the Governor of Maine proclaimed that state alien residents were required to register. Over 30,000 did so. Today several record sets are available to us: summary datasheets, registration cards, and the registration documents themselves.
You can browse or search the various collections. Click on the record category to limit your search. If you use the search form in the upper left of the landing page, you search all record categories at once.
