Digital BW, The Print

Hello,

In the past months I've been working on improving my skills as a bw 
digital printer. 
I know that any book or even a bigger tutorial about Quad(hex)tone 
printing would be propably very soon out of date.
Things are moving very fast in this field.
 There fore Iam seeking for recomendations on books, escpecially 
about Photoshop techniques that could be usefull in a Digital BW 
Darkroom.
My Photoshop knowledge is still very basic. What should I read to 
become a better quadtone printer?
I remember reading once on this list about Photoshop for 
Photographers, I don't remember the Author.

Any suggestion will be appreciated,

Maybe there are good tutorials on the web?

Greetings

Piotr
