If you search “free book” in the Kindle store, each page of Kindle eBooks is sprinkled with eBooks that cost money but are about Free Books! I’ve listed by number the order they appeared. (Blog subscriptions about free Kindle eBooks that cost $ were not included.)  After I noted the first ten, I skipped ahead randomly and found Not Free, Free Kindle Book guides for specific genres, which might be more helpful to someone.  More symptoms of the Kindle Store’s illogical search system.

Would you pay $ for an eBook list of free eBooks when you could look them up yourself?
Apparently some people will.
