What is EPUB?

An EPUB book is a digital book, or ebook, which can be read on a wide variety of digital devices including Tablets, Smartphones, Laptops and dedicated eReaders. It's this wide adoption that has allowed it to become the most dominant book format across the world, second only to Amazon's Kindle format in the U.S. and Europe.

EPUB is the successor to the Open eBook Standard, and became an official IDPF (International Digital Publishing Forum) specification in October 2007. In the spring of 2010 the IDPF made plans for the next iteration and after many months of hard deliberation they formally release EPUB3 in October 2011.

The Technology

A discussion on the technology behind the specification would be a large undertaking but with the release of the EPUB 3 Best Practices, I've decide to refer you to that. However, I would like to share a paragraph from the opening chapter as it gives one of the best descriptions I've seen;

One of the most common misconceptions about EPUB is that it is a “flavor” of XML. (“Should I use EPUB or DocBook?” or, even worse, “Should I use EPUB or HTML5?” Hint: EPUB (pretty much) = HTML5.) Due partly to the convenient single-file format provided as .epub, people sometimes fail to realize that EPUB is not just, and not mainly, a specification for the markup of content documents. It is a publication format, and as such it specifies and documents a host of things that publications need to include—content documents, style sheets, images, media, scripts, fonts, and more, as discussed in detail in the other chapters of this book. In fact, EPUB is sometimes thought of as “a website in a box,” though it is actually much more than that. -- EPUB3 Best Practices, 2013, O'Reilly.

Documentation

The latest incarnation of the IDPF format is a much more involved specification than previous revisions and if you are not the kind of person who enjoys wading through pages and pages of technical specifications (few of us are) then there are perhaps three good books available which will make the whole process much more enjoyable. Even better, two of them are free downloads!
