The Scots-Irish Influence in Appalachian English

I ran across a PDF--probably a college or graduate school paper--entitled "The Scotch-Irish Element in Appalachian English: How Broad? How Deep?" For those of us who grew up in the Appalachian Mountains, are indeed of Scots-Irish heritage and have (or at least once had) the accent made famous by Dolly Parton and Loretta Lynn, this paper is quite interesting. Enjoy!
