All the books that Carl and Matt suggested are the one's I would pick also.
My list for advanced Techniques would be:
1.)
Bonsai Techniques ll by John Naka
2.)
The Bonsai Art of Kimura by Stone Lantern Press
3.)
Bonsai Today Magazine by Stone Lantern Press
4.)
Bonsai Design-Japanese Maples and Bonsai Design-Deciduous and Coniferous Trees by Peter Adams
5.)
Bonsai,The Art and Technique by Dorothy S. Young- it's more of a textbook. May be out of print.
There really aren't a lot of
Advanced books out there!
I suppose if your that advanced you don't need too many books.
