All about EPUB 2.2

The EPUB (or Electronic Publication) is the free and open format standard in the ebook industry. This standard is maintained by the International Digital Publishing Forum (IDPF), a non-profit organization of the world's largest publishers and technology enterprises, of which Flipside is a member.

The EPUB format runs on most e-Readers and devices except the Amazon Kindle e-ink readers. Currently, there are two popular versions: EPUB 2.2 and EPUB 3.
