Local History and Genealogy Research Guides

U.S. State and Territory Guides

For local history and genealogy research, it is critical to become familiar with the context of the community: geography, legal jurisdictions, population, private and public archives, and more. Visit or contact repositories at the city, county, and state level.

Explore the individual state guides, inventories of city and telephone directories, maps, and additional resources compiled by Library of Congress subject specialists to determine what records exist for your community and where you can find them.
