My site (a yelp-like site for another country) has about the same amount of traffic as you do, and I make around US$800 per month just with adsense. Adsense works best when people are looking for something valuable, which is not your case.
Your website is your commercial for your book and your career. If you have a job, the best way to monetize your site is to ask for a raise because you're now influential in the community. If not, be happy a lot of people are looking for your books; maybe its time to write more?
