We have a small local company that takes bulk book (and cds, dvds, video games, vinyl records) donations. That company has couple of retail used bookstores and also sells both retail and wholesale online but, according to their owner, most of what they get is sold for pulp.

My wife is an elementary school reading teacher and runs a yearly family book night where she takes book donations she gets all year and fills a bunch of portable tables in the gym with kids (and adult) books that are free for the taking. What is left over is taken (by me) to that local company and dumped in huge bins. If you are looking to get rid of a bunch of books I'd also suggest contacting your local schools to see if they take donations.
