The Vegetable Gardener's Bible is my #1 go to book. I also like Seed to Seed and The Gardener's A-Z Guide to Growing Organic Food.

Growing Vegetables West of the Cascades, seeing as how I live west of the cascades, it's the perfect how to. I also love this book I picked up about growing and preserving your own food. I've lent it to a friend at the moment and I can't remember the title. It has in depth descriptions of individual vegetables growing requirements, but also all sorts of useful information on how to preserve them. Like how long to leave things in pressure caners, how long each vegetable takes to dry, and how to prepare them for preservation, etc.

Oriental Vegetables by Joy Larkcom - Amazingly good. Really top notch work.

New Organic Grower - eliot coleman -

Four Season Gardener - eliot coleman - this is great for winter gardening techniques. Both coleman books required reading for market gardeners......i see he's got a new one and it looks really good too. I think i would recommend folks start with that as it is likely his current thinking and techniques.

Seed to Seed - susan ashworth - How to save seeds for all vegetables covered in very systematic and scientific way. Excellent resource for this.

When it comes to gardening books I find Rodale offers ome of the best reference books..
but I like history and Helena Rutherfurd Ely was one of the poineers of modern day gardens in her book "A Woman's Hardy Garden" wrote in 1903. It has been republished several times.

I also like garden design books one of my favorites is The feng Shui Garden by Gill Hale.

I of course have a garden library of about 100 books and enjoying jumping from book to book often. Many design books, text books, reference books and just plain good reading books.
