"Exploring the Bouzouki"
by Jim Cowdery

it is probably more useful for those playing the octave-mandola.
But it also covers backgrounds of the instrument and useful hints
on right-hand technique.
This one also has a cassette with the tunes and examples.

"Road to Rembetika"
by Gail Holst
covers the history of the Greek bouzouki and its music, the rembetika. Informative, but not too relevant if you want to play Irish music on the instrument.
(As far as I know it's out of print - try a library)
(If anybody knows about other books that might be useful for bouzouki players, I'd like to hear about them. Mail me at the below address)
