I love this site and use it as a daily (hourly?!) salve. Thousands of books at your fingertips to be had for the price of postage, amazing! I traded away hundreds of my unused and unneeded books and in return have amassed a large library of great books that I never would have bought full price. Kids books, science fiction, poetry, they have all of the genres. Other reviewers here have noted that you have to wait sometimes, but big deal, if you need a book quickly just go to amazon, and leave paperbackswap for the books you'd really like to have but don't have to read this moment.
