Book Exchange

So, you are in PI 1 (or another class) and you have to buy all these books!  The library is now out of them, and your purse has shrunk.  What are you to do?  May we suggest borrowing the needed edition from your fellow students?  And fellow students, be kind enough to lend these precious commodities?  Of course this is the honor system, but if you need a book, you can post your need here under the comments section.  If a fellow student has the book to lend, they can contact you to let you know.  Please remember to leave your email address so your fellow students can contact you.
