Where should I donate my books? I am in the Austin area and I am moving soon.  I have a metric shit ton of books and I don't want to toss them, ship them, or move them (ever afuckinggain) I love my books to death,  but in all reality I will most likely never read them again.

Where should I donate them?  I want to make a difference so I was thinking a middle school, but being in Texas I don't want them to go to waste!

To clarify I have multiple novels, "Holy" books, and multiple old text books on astronomy and history
