I want to mention a new book out on Skipstone (Mountainier Books), "Food Grown Right in Your Backyard" by Colin McCrate and Brad Halm of Seattle. Plenty of diagrams, how-to photos with the authors taking you through design, building, your garden space to growing an abundance of crops.
The book is not just focusing on the Pacific NW but the entire country. It's a thick book with just about everything you'll need to know. It's a thick book that I have not had a chance to read, just glance through, but I think if you are a visual learner like I am, the photos and diagrams will suffice.
