There is also "The 12-string guitar as played by Leadbelly", by Julius Lester and Pete Seegar, published by Oak during the 1960s. It has about 30 songs with words, melody lines, and tabs, plus a bit of descriptive information about the songs and about playing the 12-string. Nice versions of Bourgeois Blues, Bottle up and go, Fannin Street, and others.The appendix mentions the "Leadbelly Song Book" as a more extensive collection of words and music.
