# Buy and read Digital Editions

Adobe Digital Editions (eBooks) are PDF files that have been packaged to protect the copyright of the author or publisher and which you can read much the same way you would any other PDF document. You can purchase Digital Editions from retailers, borrow them from on-line libraries, or exchange them among users. To buy Digital Editions from Adobe, choose File > Digital Editions > Adobe Digital Media Store, or visit http://digitalmediastore.adobe.com if you are using the basic version of Adobe Reader.

Before you can use Adobe Reader to read Digital Editions, you must activate Reader as a Digital Editions reader. If you’re not using the full version of Adobe Reader, you must first install the Digital Editions plug-in by choosing Help > Check For Updates Now and select Digital Editions and Accessibility Package. To begin the process of activating Reader as an eBook reader, choose File > Digital Editions > Authorize Devices, and then follow the Adobe DRM Activator instructions that display in a new web browser window.
