If you have a collection of old books -- paperback or hardcover -- there are two ways you can dispose of them properly. The first way is to donate them to a charity. But if your local charities won't take outdated or water-damaged books, you can recycle them. Most paper recycling bins can take books -- so long as you remove the hard spines and covers first. The interior pages are easily recyclable and can be tossed wherever you recycle magazines and used office paper. The old jackets and spines should be tossed into the trash.
