Meantime, some links worth checking out, via Fred First at Fragments from Floyd: Eastern Tennessee State University is publishing an Encyclopedia of Appalachia, in the bookstores soon.
Fred also mentions another new book about Appalachia, United States of Appalachia: How Southern Mountaineers Brought Independence, Culture and Enlightenment to America by Jeff Biggers. From a description:
Beyond its mythology in the American imagination, Appalachia has long been a vanguard region in the United States-—a cradle of U.S. freedom and independence, and a hot bed for literature and music. Some of the most quintessential and daring American innovations, rebellions, and social movements have emerged from an area often stereotyped as a quaint backwater. In the process, immigrants from the Appalachian diaspora have become some of our nation's most famous leaders.
An interesting counterpoint to James Webb's book, Born Fighting: how the Scots-Irish Shaped America.
