Hi Christina,
Our local newspapers will create a new colum for your classified ad if it doesn't fit into any other catagory they have created. I don't remember seeing anything for books, but that doesn't mean the ad wouldn't work. If it is not very expensive, and you can afford it, I would try it one time. You never know, you may get something going that others always said wouldn't work.
If you want to place a classified online, you can go to http://www.cyberhosted.com/adlandpro.html and place one on my classifieds page for Free.
