There's plenty of good literature out there!  Featured review:

Coming Home to Eat: the Pleasures and Politics of Local Foods, by Gary Paul Nabhan.  2002.  W. W. Norton & Company, New York, NY.  330 pp.  $24.95.

Inspired by a visit to his original homeland in Lebanon, where many people still grow much of their own food and save seeds of locally adapted crop varieties, Nabhan returned to his current home in southern Arizona committed to undertaking a locavore year based on what he could grow or obtain from within a 250 mile radius.  The region’s harsh, dry climate forced him to delve into the area’s time-honored food traditions, learning from both Native American and European American farmers, foragers, and hunters how to feed himself from this land.
