I was bought this book by my mother who had simply spotted it in the stock of some well know book people who leave stock and work places and school for mail order... It was a great find, considering my mother isn't in to gardening that doesn't involve flowers. Its great to look up individual crops and see what they require either when considering whether to grow them or when trouble shooting. It also contains info about pests and diseases in a limited fashion which can point you in the right direction when trying to discover what it is eating your plants or if there is a deficiency or illness. I use this book along side Alan Buckingham's Allotment Month By Month and Carol Klein's Grow Your Own Veg and between them they keep me on track and answer most of my questions, as i can cross section issues and advice and make a good evaluation.
