Now Online: Atlas of Historical County Boundaries

Atlas of Historical County Boundaries (Newberry Library) presents in maps and text complete data about the creation and all subsequent changes (dated to the day) in the size, shape, and location of every county in the fifty United States and the District of Columbia. It also includes non-county areas, unsuccessful authorizations for new counties, changes in county names and organization, and the temporary attachments of non-county areas and unorganized counties to fully functioning counties.

Researchers can use the Atlas as a resource for seeking records, to interpret and display of county-based historical data (e.g., returns of elections and censuses), or for working on state and local history projects.

    This tool puts the excellent Newberry Library historical county boundaries on top of Google Maps:

    The Historical U.S. County Boundary Maps interactive tool ( http://randymajors.com/p/maps.html ) shows you the historical county boundaries for any place and historical year you're researching. See details on when and how the boundaries changed, overlaid on a present-day Google Map.

    You can also overlay research locations on the map such as courthouses, cemeteries, churches, and libraries, and link right to them for more information.h as courthouses, cemeteries, churches, and libraries, and link right to them for more information.
