Donate old technical books?

Hey all, I'm helping my parents clear some old clutter and they have a ton (literally shelves full) of old technical books – a lot of Java, HTML, TCP, and various assorted computer stuff that is definitely no longer relevant. The newest book is probably at least 20 years old. That being said, they're all in very good condition so it feels like a shame to recycle them. Does anyone know if there is a place or organization that could maybe use these? Either for the content or the paper.

We're down in Pearland so bonus points if it's close. We asked the Pearland library but they only want books less than 10 years old. TIA!
