Basically the idiot's guide to simplicity. It has quite a few good ideas about living simply-- small (and big) changes that can make a difference. Some, of course, are more applicable than others, depending on your lifestyle. Much of the book is, well, common sense. I wish it had a bibliography of all the books mentioned and often recommended, but I'm afraid you'll just have to weed it out of the text. Pretty good overall and easy to read.
