Adobe Content Server
Adobe Content Server is software developed by Adobe Systems to add digital rights management to e-books. It is designed to protect and distribute Adobe e-books in PDF or EPUB format through Adobe Digital Editions, or applications and devices developed using Adobe's Adobe Reader Mobile SDK, covering a wide range of tablets, smartphones, and dedicated devices.
