This site provides a great way to search for ebooks based on your personal preferences.
The Fussy Librarian is the first website to match readers not only with the genre of books they like but also their preferences about content. Do you only read mysteries without profanity, violence and sex? Then we’ll tell you only about cozy mysteries. Read just memoirs and gory horror novels? No problem.
We also only bother with the good stuff so you know you’ll see great reads every time you open our daily email. There’s a reason we’re called The Fussy Librarian, after all.”
Besides helping you find books you want, it provides lists of free books (by genre), and a blog with author interviews (http://www.thefussylibrarian.com/blog/).
