it’s bad juju to throw books in the trash right?

The books you are talking about are mass produced commodity items, right? If you don’t want them anymore and don’t know anyone else who does just treat them like any other print product and toss 'em out. They weren’t painstakingly copied by monks, the knowledge inside will not be lost, just being a book doesn’t make them special.

Signed, someone who had to deal with a slew of outdated guidebooks, encyclopedias, cookbooks, reader’s digest issues, never-read novels and whatever else from a deceased relative because they just couldn’t bring themselves to put them in the recycling bin.
