Harlequin is adding interactivity to its ebooks under the banner “Enriched Editions.” The first title to get the enriched treatment is Unmasked, a romance story chosen for its historical tie-ins. From a Harlequin press release:
Unmasked … has been enriched with interactive buttons that hyperlink to Web sites containing photos, historical commentaries, illustrations, sound effects, maps, articles and more … The interactive buttons have been designed to be unobtrusive, so if one prefers not to access the bonus material, the reading experience remains uninterrupted.
The Harlequin release says Unmasked and future Enriched Editions will be sold at the same price as the publisher’s regular ebooks.
