I happen to run across this book on SCRIBD.com (http://www.scribd.com/doc/49691274/The-New-Darkroom) and don't see it mentioned on the forums here.

New stuff for me: detailed descriptions, with pictures, of the darkrooms of Harry Callahan, Aron Siskind, Berenice Abbott, W. Eugene Smith and others.

It is not my upload. Anyone interested in darkrooms might want to check it out while it is available on line.
