I second Randy's comment on Minor White's book. It is excellent, except for testing the film.
Nevertheless, the original question was about a book to determine the correct Zone System exposure. I don't htink you'll find much better than AA's 'The Negative'. But' I'm not sure that you need abook for that. Follow 'expose for the shadows and develop for the highlights' and you're fine. Some people expose for Zone III, others for Zone IV. It's tough to overexpose and easy to underexpose. If in doubt overexpose and underdevelop.
