Visited the site, dismissed the pop-up, scrolled to the bottom, saw that every book had just one mention. Wound up spending more time reading comments and looking at the list, don't think I'll return as the biggest problems do not seem fixable. You are using Amazon links as a substitute for actual linguistic processing to parse out book names. It may be possible to use the links to prime the pump by creating a list of titles, then re-scanning all comments for closer approximations of those titles but I don't know the fesability of that.
