Newly added plugins to the Moodle Plugins database brings a very useful functionality to import Epub books into your Moodle course within the Book module and vice versa.
In addition to importing an entire book, you can choose to import chapters as individual books. Similarly, Add a book activity to your Moodle course, add content to the book – either by writing or importing from EPUB ebooks, then use the Lucimoo ebook export tool to export the book as a regular EPUB ebook.
This can be handy to give students or teachers an off-line version of a book, which they can enjoy in their favourite ebook reader on their smartphone, tablet or PC, e.g. FBreader for Android or Lucifox for Firefox.
