Books and Books and Books.
First is Edward R. Tufte's Visual Explanations: Images and Quantities, Evidence and Narrative (1997)
This is a book about information design. He seems to have a hard time getting some points across.
Robert Adam and Carol Robertson's
Intaglio: The Complete Safety-First System For Creative Printmaking
This book gives a very detailed information on printing in a safe environment. The book gives good step by step for etching and great planning details for a print shop.
I have three other books to put up as well. Perhaps tomorrow.
