ebooks: What is DRM-Free

All ebooks purchased and downloaded directly from Airbooks are DRM-Free (without digital rights management). DRM is copy protection or access control to digital content that’s applied to ebooks.

Customers who buy DRM-protected books won’t be able to share the book on their different devices, and could have problems in the future when hardware and software change. There can also be restrictions with the territory it is accessed from, and there have been cases where retailers have removed the book from the readers device.
