2. Send in your favorite titles to add to the Green Days Book Club library.
3. Read and release. Got an old copy of a book that’s so good you just have to pass it on? Register the book at www.bookcrossing.com, write its new Book Crossing ID number on the inside cover (and a little note telling the next person to visit the site) and leave it in a public place where someone is bound to pick it up. Track the travels of your book as it changes hands over its lifetime.
