The Goodreads API allows developers access to Goodreads data in order to help websites or applications that deal with books be more personalized, social, and engaging. The API can be used in many ways, including:
Review Syndication: Goodreads has 10 million reviews across 700,000 titles. The API lets users display these reviews on their website.
Goodreads Connect: Members can connect to their Goodreads account, and developers have full access to the books, ratings, and reviews the member has in their shelves, as well as the member's friends. This can be used to personalize an ecommerce store, power recommendations, show a widget of a member's favorite books, build a mobile or desktop client app, and more.
The API uses RESTful calls and responses are formatted in XML.
