Here are 10 easy ways to recycle books, and a quick video how-to.
Throw a book swap party. Get a few bottles of wine (organic and fair trade, of course) and get together your friends, family or neighbors for a book-swapping party. You can make up "rules" if you wish, or just let people dive in and help themselves.
Donate your books to your local library. You can feel great knowing your old books will be read by hundreds more people.
Take them to your local charity, thrift or goodwill shop. Profits raised from your books can help other people benefit from a better life.
Donate on Freecycle. You might even find yourself a like-minded friend from your neighborhood in the process!
5. Sell them on Green Metropolis. If you're in the U.K., you can sell your books on Green Metropolis, which donates money to the Woodland trust for every book sold.
Sell on the Internet. Make some money on eBay, Amazon or in a second-hand bookshop.
ReadItSwapIt. Do as the name suggests, and ReadItSwapIt. You'll meet a virtual community of people who want to read your book and swap their own. Paper Back Swap offers a swap site for U.S. readers.
Become a Book Mooch. BookMooch offers a similar system, but instead of swapping, you earn "points" for every book you give away, which you can use to "buy" other people's books.
Set your books free. BookCrossing is a wonderful idea — you just leave your books on a train seat, in a restaurant or at a hotel for a new reader to find! You can "tag" your book with a unique code and follow your book as it travels across the world.
Share the love. A local hospital or hospice would love to take your old books from you for patients to enjoy.
Educate others. Take children's books to a local school and specialist textbooks to a local college or university.
