You can count the number of books in the world on 25,972,976 hands

Ever wonder just how many different books there are in the world? After some intensive analysis, we've then come up with a number. Standing on the shoulders of the giants—libraries and cataloging organizations—and based on our computational resources and the experience of organizing millions of books through our Books Library Project and Books the Partner Program since 2004, we’ve determined that number.

As of today, we estimate that there are 129,864,880 different books in the world. That's a lot of knowledge captured in the written word! This calculation used an algorithm that combines books information from the multiple sources including libraries, WorldCat, national union catalogs and the commercial providers. And the actual number of books is always increasing.

Ultimately, it is truly incredible to the fathom the depth and breadth of the published works out there in the world. To find out how we calculated this number (no, we didn’t count them on our fingers:), check out the Google Books blog.
