Google launched the data highlighter tool in December to make it easier for website owners to add rich snippet data to their web pages. Google last added six new data types a few months ago to the tool and now has added support for book reviews.
Google's Pierre Far announced on Google+ that the data highlighter now officially supports book reviews markup. You can use Data Highlighter to tag data about a book, such as its title, author, reviews, and reader ratings. You can read the technical details around the support in the Google help section.
