I have been diligently culling through my books as of lately. There were a couple that seemed pointless to have after I finished school and there were others that I found for free in an eBook format online. I sold at least 8 and one set at the used bookstore yesterday for $9. It doesn't seem like much but I really wasn't expecting that they would even be worth that much! I also lucked out and sold my last textbook online very quickly! I am now down to 75 books as keepers. Not bad at all!
