What is the European Accessibility Act and how does it affect ebook publishers?
The European Accessibility Act (EAA) is EU Directive 2019/882. It requires that ebooks placed on the EU market from 28 June 2025 meet accessibility standards, specifically the EPUB Accessibility 1.1 specification, which references WCAG 2.1. Publishers who sell ebooks in EU member states must ensure new titles are accessible. Back catalogue titles placed on the market after the deadline are also covered.
What is EPUB Accessibility 1.1?
EPUB Accessibility 1.1 is a specification published by the W3C that defines how an ePub3 file should be structured to be usable by people with disabilities, including those using screen readers or other assistive technology. It references WCAG 2.1 for content requirements and adds ebook-specific requirements such as reading order, navigation, and accessibility metadata in the package document.
