Please read! I've been down this road before, but no body listens. Naturalization records Only one comprehensive name index to Indiana naturalization records is available - An Index to Indiana Naturalization Records. This book, published by the Indiana Historical Society, consists of names compiled by WPA researchers from county court order books, which are the ledgers and volumes containing the records of all court decisions; it does not include names in <A HREF="http://www.in.gov/serv/icpr_naturalization"> naturalization record books,</A> which were specialized volumes containing only naturalization records. Court order books are considered critical records and must, by law, be retained in the county of origin; accordingly, the county clerk of court is the only source for records listed in this index. Naturalization books were not always considered critical records and some counties did not maintain or preserve them; of those that survive, a significant percentage were transferred to the State Archives, but others are still kept locally. No overall and, in many cases, no specific name indexes are available for them. Patrons can contact the State Archives about all these records, but they should keep in mind the distinction between the two. Very often, confusion about the location of the court order books arises, but the law is quite clear on the issue - copies must be retained locally, so the county clerk of court is the only source of information on records listed in An Index to Indiana Naturalization Records.
