John Alexander Williams defined the core region of Appalachia as those counties found in all six of the six “classic” definitions of Appalachia, which he named as those that “individually and collectively shaped most general accounts of the region”: 1) Berea by Frost and Hayes, 2) Campbell, 3) U.S.D.A., 4) Ford, 5) ARC, and 6) Raitz and Ulack. His 2002 book, Appalachia: A History made his definition of core Appalachia widely available. Our version of Core Appalachia includes the most recent definition of ARC Appalachia that would have been available to Williams at the time of his book’s publication in 2002.
