Adobe Digital Editions (abbreviated ADE) is an ebook reader software program from Adobe Systems, built initially using Adobe Flash. It is used for acquiring, managing, and reading eBooks, digital newspapers, and other digital publications. The software supports PDF, XHTML (through the non-proprietary EPUB file type specification) and flash-based content. It implements a proprietary scheme of Digital Rights Management ("DRM") which, since the version 1.5 release in May 2008, allows document sharing among multiple devices and user authentication via an Adobe ID.
