Either Kerr or Ball Canning Book. If you purchase a pressure cooker, it usually comes with a manual with very good instructions. My bil listened to Glenn Beck and he suggested stocking food and he did. Went out and bought a pressure canner, stores were have a sale on pork. Sam's he bought a case of hamburg and canned that too. Canned beef for stew. His closet is so full of canned food, it'll take him a couple of years to use. But his food bill will be reasonable.
