What is Adobe Digital Editions (ADE)

[any ANONYMOUS forum user]

Adobe Digital Editions (ADE) is ebook reader software from Adobe Systems built 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 nonproprietary .epub file type specification), and Flash-based content. It implements a proprietary scheme of Digital Rights Management (DRM), which since version 1.5 (May 2008) allows document sharing between multiple computers and user authentication through Adobe ID.

Windows and Mac OS X versions of Adobe Digital Editions were released on June 19, 2007. The software requires version 9.0 of Adobe Flash Player. Adobe originally announced a Linux version would be published at the end of 2007 but later changed their mind. All promises of future versions have now been removed from the Adobe’s official FAQ.
