County Records on Microfilm
The Idaho State Historical Society Library and Archives (L&A) holds microfilm copies of county records from around the state. Included are citizenship, civil and criminal court, land and property, wills and probate court, tax, and vital (birth, marriage, death) records. County Records on Microfilm is an index to those materials. Some microfilm is also available from LDS Family History Centers, but much is available only from the L&A.
