Japanese Woodblock Print Workshop: A Modern Guide to the Ancient Art of Mokuhanga By April Volmer
Published by Watson-Gupthill Publications
Full of beautiful photographs, contemporary and historical examples as well as practical advice.
This is the only book I know of on woodblock printing (in English) currently in print, but I can recommend these two if you can find them from second hand dealers.
