Garrish - Accessible EPUB 3

Accessibility is a difficult concept to define. Theres no single magic bullet solution that will make all content accessible to all people. Perhaps thats a strange way to preface a book on accessible practices, but its also a reality you need to be aware of. Accessible practices change, technologies evolve to solve stubborn problems, and the world becomes a more accessible place all the time.

But although there are best practices that everyone should be following, and that will be detailed as we go along, this guide should neither be read as an instrument for accessibility compliance nor as a replacement for existing guidelines.

The goal is to provide you with insights and ideas into how to begin making your publications richer for all readers at the same time that you make them more accessible. Proliferating usability guidelines and muddying the waters of compliance is not its intent. There are areas that would take a book unto themselves to explore in detail in relation to the use of HTML5 content within EPUB, such as the Web Content Accessibility Guidelines (WCAG) and Web Accessibility Initiatives Accessible Rich Internet Applications (WAI-ARIA). Whenever issues extend beyond what can be covered in these best practices, pointers to where you can obtain more information will be included. Dont fall into the trap of hand-picking accessibility.

It is also naturally the case with a standard as new and wide-ranging as EPUB 3 that best practices will evolve and develop as the features it offers are explored and implemented. This guide will endeavor to make clear whenever uncertainty exists around an approach, what alternatives there are, and where you should be looking to watch for developments.

You need to be thinking about accessibility and planning good content practices from the outset if youre going to make the most of the features EPUB 3 has to offer. This guide will be your map, but you have to be willing to follow it.
