EPUB 3 Becomes Final IDPF Specification

October 10, 2011

Frankfurt, Germany, October 11, 2011. The International Digital Publishing Forum (IDPF) today announced the completion of a major revision to EPUB, the global standard interchange and delivery format for eBooks and other digital publications. The IDPF membership unanimously voted to elevate EPUB 3.0 to a final IDPF Recommended Specification, publicly available at

EPUB 3 was chartered in May 2010 and developed by a global working group of over 100 contributors, reaching Proposed Recommendation status in May, 2011. Based on HTML5, EPUB 3 adds support for rich media (audio, video), interactivity (JavaScript), global language support (including vertical writing), styling and layout enhancements, SVG, embedded fonts, expanded metadata facilities, MathML, and synchronization of audio with text and other enhancements for accessibility.

"EPUB has become the industry standard format for digital publications based on Web Standards that are structured, reliable, device-independent, and accessible," said BIll McCoy, Executive Director, IDPF. "As digital publications evolve from digitized text into enhanced eBooks and new forms of expression, EPUB 3 will dramatically expand the ability of authors and publishers to deliver richer experiences to their readers across disparate devices, in browsers and in apps.".

EPUB 3 features have already  been delivered by a number of Reading Systems and content authoring tools.  Now that EPUB 3.0 is a final specification, superseding EPUB 2.0.1 as the current version of EPUB, the IDPF anticipates that comprehensive EPUB 3 support will be forthcoming from a number of solution providers during the coming year. Industry stakeholders who publicly expressed support for EPUB 3 when it achieved Proposed Recommendation status in May, 2011 included Adobe, Apex, Association of American Publishers (AAP), CourseSmart, EAST, EDItEUR, Google, HOV Services, IDEAlliance, Ingram, Italian Publishers Association (AIE), Japan Electronic Publishers Association (JEPA), Kobo, Monotype, MPS, OverDrive, Publishers Association (UK), Random House, Sony, Voyager Japan, and the World Blind Union.
