What Should I Read Next? is a very excellent link that someone tagged me in on Pinterest. I went to the link and it offered a treasure trove of suggestions based on an author that I entered.
Launched in 2010, it gives you the ability to enter an author, book title or ISBN number. This is how it works, according to its FAQ:
WSIRN produces recommendations based purely on collective taste: when books are entered into the same favourites list, they become associated with each other. The more often particular items appear on different lists, the stronger that association becomes. Purely and simply, WSIRN represents mass opinion about books. Over time the recommendations should get better and better as the database grows. (Note that books by authors you have entered won't appear in the results - we've assumed that you've thought of reading those!)
If you enter your email address, it will remember past books, favorites and recommendations. The site promises that they will only send the occasional email about updates to the site and will not share the email with any third party. I haven't used it extensively yet, but plan to try it out. Will let you know!
