One of the earliest collectors of Appalachian ballads was Kentucky native John Jacob Niles (1892–1980), who began noting ballads as early as 1907 as he learned them in the course of family, social life, and work. Due to fears of plagiarism and imitation of other collectors active in the region at the time, Niles waited until 1960 to publish his first 110 in "The Ballad Book of John Jacob Niles". The area covered by Niles in his collecting days, according to the map in the "Ballad Book", was bounded roughly by Tazewell, Virginia; south to Boone and Saluda, North Carolina and Greenville, South Carolina; west to Chickamauga, Georgia; north through Chattanooga and Dayton, Tennessee to Somerset, Kentucky; northwest to Bardstown, Frankfort, and Lexington, Kentucky; east to the West Virginia border, and back down to Tazewell, thus covering areas of the Smokies, the Cumberland Plateau, Upper Tennessee Valley, and the Lookout Mountain region.
