Atlas of Historical County Boundaries Now Available Online

The Newberry Library is pleased to announce the completion and release of its Digital Atlas of Historical County Boundaries website, http://publications.newberry.org/ahcbp, a dataset that covers every day-to-day change in the size, shape, location, name, organization, and attachment of each U.S. county and state from the creation of the first county in 1634 through 2000.

With the Newberry’s Atlas of Historical County Boundaries, genealogists, geographers, historians, political scientists, attorneys, demographers, and many more now can find accurate county data that will greatly assist them in their research.

The data is organized by state and is available online. Supplementing the polygons and maps for each state are chronologies, commentary on historical problems, long and short metadata documents, and a bibliography.
