Accessibility - EPUB 3 Resources and Guidance

There is a range of guidance available for creating Accessible EPUB files - some high level and some more technical. DAISY has pulled together a page here which provides best practices for creating accessible EPUBs.


The epubcheck tool is the gold standard as far as EPUB 3 validation goes. epubcheck is currently hosted on a github project under the same name. The latest stable build is typically linked to from epubcheck’s main page, but can also be found by clicking on the Downloads tab. An online version of the tools is available here.


The website epubtest.org is a collaboration between BISG, DAISY Consortium and the IDPF to provide a unified home for the definitive EPUB 3 Reading System Conformance Testsuite.

The following list is the complete list (as of October 2018) of all the EPUB specifications. The latest version of the EPUB spec is 3.2, but it is still in draft format as of late October 2018.
