What is ePub?
It is a very famous format used for many free and open electronic books, e.g. at the Project Gutenberg, but it also supports DRM. Supporting re-flowing content, it is ideal for mobile devices such as phones and tablets. The Playstore provides plenty of reading apps supporting this format, such as e.g. Moon+ Reader and Aldiko Book Reader.
