Issuu, the Danish startup battling the likes of Docstoc and Scribd in the professional document publication and sharing space, is today introducing a REST-based API that enables its users to automatically upload and manage publications, bookmarks, and folders under their accounts. That means developers and designers can henceforth tap into the Issuu platform and services to equip their own applications and websites with the oft-needed functionality of offering document consultation without the need for end users to download the docs or to visit the Issuu website.
