Jean Ritchie's Folk Songs of the Southern Appalachians was published by Oak Publications in 1965. It was reissued by The University Press of Kentucky in 1997, and is for sale at Jean's Website. It's in the familiar Oak Publications songbook format.
I'll post the Table of Contents below, and maybe I'll change the songs names into clickable links later.
Jean, any comments on the book? Any background information/comments on the Oak Publications songbook format?
