Idaho Archives and Libraries

The records of the events in the lives of our ancestors generally fall into three categories -- those kept by government offices, those kept by churches, and those kept by individuals, businesses, or organizations.

Government records are normally kept in archives at various levels of government -- city, county, state, or national. Church records are usually housed at the local church congregation level, although some may have been collected to a denominational archives. Private records often remain in the possession of the business or organization or with the descendants of the ancestor. Some private records have been collected by historical or genealogical societies.

County Courthouses and City Offices
Many of the key records essential for genealogical research were created by local county or city governments. County records include court, land and property, naturalization and citizenship, probate, taxation, and vital records. The county courthouses are the primary repositories of these valuable records. Some courthouse records have been destroyed. Many have been microflimed and/or transferred to the state archives. The Family History Library has microfilm copies of many of the earlier records of the counties.

Easy-to-use sources that list the various county offices in each state and the types of records at each office are:


 * Bentley, Elizabeth Petty.County Courthouse Book. (Baltimore, Maryland: Genealogical Publishing Company, 1995.) ; .)
 * The Handy Book for Genealogists: United States of America. Tenth edition. (Logan, Utah: Everton Publishing, 2006.) ; .) The Handy Book also lists the county seat and zip code.

City offices have records of the minutes of the mayor's office, city council, and other records relative to the government on the local level. While they may not contain a large amount of genealogical information, they are a valuable source of personal history of the officers and residents of the smaller localities. Most of these records remain in the local offices.

Historical and Genealogical Societies
Historical and genealogical societies have been organized in each state, most counties, and some towns. These societies collect many valuable records and offer various helpful services to researchers.
