This thread is discussing (and perhaps confusing) two different books.

The original request concerned "Eighty English Folk Songs from the Southern Appalachians" collected by Cecil J. Sharp and Maud Karpeles. It was (c) Faber Music in 1968, and issued in the United States by MIT Press (with apparently later reprints).   It is around 110 pages, and square format about 7.5 inches square. It includes sample piano accompaniments by Benjamin Britten for four songs, and chord symbols for guitar by Pat Shaw for many songs. Used copies are available online for under $20.

"English Folk Songs from the Southern Appalachians" in two volumes, first published in 1932 and recently reprinted by Loomis House/CAMSCO (thank you to all involved!!), contains 274 songs with many variants.
