Unrelated, but useful

A recent study of the American publishing industry estimates that from forest to landfill, the book business emitted about 12.4 million tons of carbon dioxide in 2006. Resize that carbon footprint by opting for used textbooks. Web sites such as Bookbyte.com, Campus Book Swap, and Buy Used Textbooks offer opportunities to buy and sell books. Want to your purchasing power to do double-duty? Pick up that required copy of The Catcher in the Rye from Better World Books and your money will help fund literacy programs worldwide. Better World Books also accepts donations of "no value" books; according to their Web site, they've saved 6,500 tons of books from landfills.
