The How and the Tao of Old Time Banjo
“What have you got, kid?” The old man asked me around his cigar.
“A banjo!” I replied.
“I know that you little dipstick.” He said rolling his eyes “You think somebody as old as I am hasn’t seen a banjo before? What have you got? Play something.”
An excellent book on old-time clawhammer banjo, published under creative commons license. The author has also some amazing video tutorials on youtube
