As I remember, they've always been paperback. Libraries carry them....excellent books and info.

Here's an amazon search link.

Thanks, karin and wcgypsy. Is there a specific edition I should be looking for??

I don't think you need to worry about which edition too much. Get the most recent one you think is reasonably priced. Mine is quite old, but it's the most useful garden book I own.

Her books are great! I was fortunate enough to hear her speak several times, and she autographed my copy of Southern California Organic Gardening. The book was softcover. If hardcover were available, they probably would have had it at the autograph session. You'll enjoy the book.

She recently redid her magnum opus in an "organic" version, but the original wasn't all that gun-ho on chemicals. Any one you can find is very useful.
