I was just wondering if there are any good acoustic guitar books out there with good lessons?

I have been playing guitar for about 4 years, but am stuck with rock playing on the electric guitar.

Would like to change gears to acoustic playing. Been inspired by Jack Johnson and Eric Clapton.

Any recommendation?

books are old school aren't they?

What about a site www.guitartricks.com it's cheap for a monthly membership. I personally think books are a rip off. I learned from books.. but that's only because I'm one of them old bastards that was born before Internet.
