EPIC TOMATOES or How To Select & Grow the Best Varieties of All Time, by a recognized expert responsible for several of the most popular open-pollinated tomato varieties, is the most complete volume on tomatoes I have read. Lavishly illustrated, it starts with the origins and anatomy of the tomato, moves on to Planning, Planting, Growing and Harvesting, and includes chapters on Saving Seeds, Breeding your own varieties, and Troubleshooting pests and diseases. His answers to many of the usual questions about tomato growing shoot down many myths, and his listing of resources includes a table of 250 recommended varieties. Highly recommended.
Along with Carolyn Male's book on Heirloom Tomatoes, this will become a staple of my garden library.
