oh you can find many uses for old text books. They make great stands, stack a couple on top of each other and there you go. My modem has never been happier on top of chem, bio, and physics. But I'm actually saving most them for my bro when he goes to uni. I got 6 g's worth on scholorships this year, it paid for my tuition and books, so I could sell them back and make profit.
