Those are a great place to start, as well as the organizations who assist other countries' literacy!

I've helped at library book sales for years and we'd always get tons of old text books. Some people actually buy them, though the ;library doesn't selll them for much anyway. But that's my suggestion, support local library or Friends of the library if they have a branch near you.
