Ok. I've prided myself on having practically my own personal library. That said, however, I've managed to acquire enough to fill a room on their own (and many I no longer use). It's made me wonder what others do with their old books? I did find out that the local library will take them and whatever they don't use they will sell (which is fine for me as I'm a big supporter of libraries and literacy programs).

So what do you do with your old tech books?
