Reddit mentions of Printmaking: A Complete Guide to Materials & Processes

Unfortunately there are no quality printmaking magazines out there to my knowledge. Art on Paper was a real gem, but they folded last year. There are, however, a bunch of great blogs and websites. If you're looking for specific technique instruction, for litho there is no more definitive source than Tamarind. http://tamarind.unm.edu/tam_techniques.html

For more general techniques across all printmaking disciplines, Bill Fick's Printmaking guide is a great resource.http://www.amazon.com/Printmaking-Complete-Guide-Materials-Processes/dp/0205664539

Online I would recommend printeresting.org From there you can find a bunch of other stuff on the links page, but I check printeresting every day, and every printer I know does too.

Since you mentioned woodcutting, you might enjoy this video of Bill Fick showing off his great linoleum technique.http://billfick.com/2011/02/07/anatomy-of-a-linocut/
