I got a book when I was about 15 or so from a high school music teacher. It was called "The Joy of Guitar" It's got some great standard folk songs and I think it's still around. Also I got a chord chart that was arranged by key. Even though I really did'nt understand it, just trying to play the chords was a big help. Pretty soon I was playing along with Bob Dylan, Neil Young, Kingston Trio records as well as jamming with friends. It's all there but ya gotta really want it. And it helps to want it every day for at least an hour or two, that's the important thing.
