Cook County, Illinois, Declaration of Intention Database

From their website:

The Clerk of the Circuit Court of Cook County Archives is home to more than 500,000 naturalization petitions covering the years 1871 to 1929. More than 400,000 of these records are Declarations of Intention, 1906-1929 which were usually the first papers to be filed by those who wished to become U.S. citizens.

These declarations are searchable--but note the website indicates that the database is incomplete.
