Digital Rights Management (DRM) is any technology used to govern content on an electronic device. In the case of ebooks, it is encoded into the format and limits the ability to copy, print, and share ebooks.
The most widely used eBook formats are ePUB and PDF.
Apps exist which can convert ebooks to different formats, although the ebooks must be free of DRM.
Wishing a book was available in an ebook format DRM-free? Unglue.it is a crowdfunding initiative to make already published works freely available to the world. Check it out!
