Guide to Optimized Publication Standards


This page provides information about standards for creating Optimized EPUB Publications, which are publications that have been specially designed to address the needs of a specific reading modality.

This document should not be read as a formal registry, as the EPUB 3 Working Group does not control how conformance to any standard is expressed.

Refer to the EPUB Accessibility specification for more information about these kinds of publications, and how to include the standard identifiers in the Package Document metadata.

To request the addition of a standard to this list, please open a new issue in the tracker.


Inclusion of standards in this guide does not constitute endorsement of them by the EPUB 3 Working Group or the W3C and its board or membership.
