Mastering Algorithms sounds great. I live in Tucson, AZ but could paypal you shipping. Is there a particular type of book you would want to trade for? My library is small but has a few gems.
Paypal would be fine, and no need to feel obligated to trade, I'm just trying to lessen the load on my shelves, especially if someone will make use of it. Hit me up danieltpeters at the mail of the great g ;)
