Bookish is a book recommendation site that features exclusive book excerpts, interviews with authors and editor’s picks. It’s an interesting mix of algorithms and real people.
You can sign up for an account and get personalized reading recommendations, but you can also just browse anonymously if you wish. Enter a title, and Bookish offers up one based on genre, subject, characters, awards, and critical reviews. You can read samples online, and they also offer a weekly newsletter. Be aware that it is skewed to new (and popular) books.
