Alicia, The book I have is called "Woody Gutherie Songs" from TRO Ludlow music. It is edited by Judy Bell and Nora Gutherie. It is an excellent resource and I got it from Elderly Instruments. Go to WWW.elderly.com, push the books button, go to personality's and you will find two books on Gutherie. Both are in the $8.00 range.
All the best,
