HarperCollins is a large book publisher. HarperCollins publishes a wide variety of genres, including fiction, memoirs, business books, biographies, cookbooks, and children's books.
The HarperCollins API allows developers to access and integrate the HarperCollins book information, such as authors, titles, and previews, with other applications and to create new applications. Some example API methods include retrieving author information, retrieving book previews, and retrieving other book information.
Big news for bookworms: HarperCollins, one of the "Big Six" New York publishers, has launched its OpenBook API Beta (not to be confused with the "Openbook" Facebook parody site), giving developers access to a wealth of data about their books and authors.
