The Associated Press is the latest organization to join the royal wedding book sweepstakes. The AP will publish a book of photographs next week using MyPublishers.com, the photo book self publisher. Twenty-one AP photographers are shooting the day’s events and will upload the selected pictures to MyPublisher over the weekend. Books will be available only through MyPublisher through print-on-demand with no retail distribution planned. Prices have not been set for the untitled book which will be available in hardcover plus a deluxe hardcover edition.
