Since the release of BookPsychic, LibraryThing’s first-of-its-kind recommendation service for library patrons, we’ve received a lot of feedback, and implemented four major changes.
Authors you’ve read. Some reviewers found BookPsychic recommended too many books by authors they had already read. Others thanked us for a useful way to discover backlist titles by authors they loved. The issue is basic. While BookPsychic, like LibraryThing, tends to “recommend down”—from more popular to more obscure books by an author—it certainly does recommend books by authors you rate.
Instead of establishing a new rule, like “no recommendations for authors you rate,” we decided to treat this as a display issue. Same-author recommendations should be there, but they should be clearly separated somehow.
To implement this we came up with a recommendation section for “Recommendations by authors you have rated” (seen at right). So the high-volume Danielle Steel reader can stop dealing with so many books you already know about, but the teenager who recently finished The Lord of the Rings can discover The Silmarillion or The Children of Húrin.
We also push same-author books back somewhat in the genre browsing. You’ll see them, but fewer of them.
Search. BookPsychic was designed as a recommendation system integrated into your OPAC, not an OPAC itself. So the first version passed you back into the OPAC when you wanted to search. But some reviewers found this clunky, and wanted a quick way to search for books to rate.
So we added a search box. It’s simple to use and keeps you in BookPsychic. You can rate items right from the results.
Other authors. Together with the search box, we added a back-of-book button for “more by this author.” It’s a handy way to give Steel or Tolkien a dozen thumbs up.
Coverage. BookPsychic’s coverage continues to improve, with most libraries seeing 55-75% of their ISBNs falling into one or more of its preset genres. A higher percent can be recommended, and everything can be rated.
The system now also picks up non-ISBN items in your library collection, and we’ve added a new genre for “Art and Design.” We’re eager to develop more genres, as wanted.
Speed. It’s faster!

What is BookPsychic? Launched in August, BookPsychic is an easy and fun personal recommender system for library patrons—like Netflix or Amazon, but all about what’s in and what’s popular at your library. As you rate books and DVDs, BookPsychic learns more and more about your tastes, and comes up with recommendation lists. And everything shown or recommended is available at your library. Simple “bookstore” genres, like “Recent fiction” and “History,” help you zero in on the books you want.
