  • Description The Atlas of Historical County Boundaries 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. The Newberry Library makes these data available without charge over the Internet in two digital formats: as shapefiles that users can download for use with geographic information system (GIS) software and as interactive maps, derived from the shapefiles, that users can view and manipulate.
