Great Book

A couple weeks ago I found a great book at our library by Sandra Perrin called Organic Gardening in Cold Climates.  It has everything a vegetable gardener could want in a book.  It's been around since 1991 and I can't believe I never discovered it before.  I checked online and a revised edition came out in 2002 with a second printing in 2007 but it now seems to be out of print - at least I can't find any new ones available on Amazon or Barnes and Noble.  I managed to get a copy from a used book seller through Amazon and it arrived in the mail just this morning.  I can't understand why such a wonderful book would be out of print . . . and it seems a shame that Sandra isn't seeing any benefits from all the used books being sold.  I can see it becoming my gardening bible.
