Book Extras

Book Extras is one example of the many areas where Amazon is innovating to improve the book shopping experience. Book Extras contain information about the book added by the Shelfari Community, which consists of authors, Amazon customers, and users. Information can include series information, character descriptions, settings and important places, memorable quotes, and more.
