EPUB, short for “electronic publication,” is an open standard format for eBooks. As an open standard, it has great compatibility across a wide range of eReaders and has become the de facto universal standard within the eReader sector. As eBooks started to gain mainstream acceptance, many companies started to manufacture and market their own eBook readers. The problem with this is that the lack of a unified standard means that many of them created their own. The advent of ePub aims to create a unified standard for eBooks. As ePub is a format for eBooks, an ePub file is also an eBook.
