A Month of Reusing - Reuse Books

Reuse books. The library is obviously the best resource for this. But, if you simply must buy the book, you can always buy it used on Amazon, and then re-sell it at the same place when you're finished with it. Or, there are places like Bookcrossing.com (n. the practice of leaving a book in a public place to be picked up and read by others, who then do likewise.) and Titletrader.com (a book swapping website) that you can send and receive books for the price of postage.
