Free Idaho Directories are available online. This list will continue to be updated.

City directories contain an alphabetized list of residents with their addresses, spouse’s name, professions, and often a reverse lookup by address. They often contain historical information about a locale and they’ll usually contain a separate business directory.

Gazetteers contain descriptions of towns, churches, terrain, populations, and more. They may include place names, maps, boundaries, and distances between cities.
