State by state, county by county, city by city, the Guide to Naturalization Records identifies all repositories of naturalization records, systematically indicating the types of records held, their dates of coverage, and the location of original and microfilm records. The Guide also pinpoints the whereabouts of federal court records in all National Archives facilities. But perhaps the most unique feature of the Guide to Naturalization Records is that it identifies every single piece of information on naturalizations that is available on microfilm through the National Archives or the Family History Library System, including the call numbers used by each institution. Records that are available on microfilm through other facilities have also been included.
Other special features of this work include an overview of the history of naturalization and citizenship, a special appendix on Native American tribal citizenship records, hard-to-find information on the records of Japanese and Chinese Americans, and records of internment of American citizens by the U.S. Government.
