Save a Tree, Swap a Book...Online!

If you're looking for another way to find interesting books but reduce the number of new books you purchase, consider online book-trading through swapping websites. They work like this: You join. You post the names of books you're ready to trade away. You look for the books you want to acquire. Trades are arranged and you mail your old books and receive new ones.

That said, there are important differences between the services -- in cost, convenience, trading process and availability of your kind of books. Three websites- swaptree, zunafish and bookins - all offer trading services of various kinds. Check them out and see which one best suits you. For more information on book swapping and how to do it, read Sheryl Eisenberg's account at http://www.nrdc.org/thisgreenlife/0808.asp.
