Your book listings seem to be missing big time on SEO potential, no? I think you should have individual pages for each textbook, with proper on-page optimization (title, H1, small paragraph of text...). That's probably a lot of work, but can you test it on a subset? Then you see if it's profitable and you could hire someone to write the remaining descriptions. That brings us to the monetization: you should do the math - traffic levels, CPC, CTR (for that you could try to have ads on a few pages). I don't have that much experience with ads but from my experiments with a few websites, ads might make sense in a situation and not in another... So you have to test.
