Note

My hope is these sections have given you an easy introduction to ARIA and the features it provides to make EPUB content accessible

For additional information, some good starting points include: the coverage given in Universal Design for Web Applications by Wendy Chisholm and Matt May (also an excellent guide to accessible Web content development); Gez Lemon’s introduction to creating rich applications; and, of course, the authoring practices guide that accompanies the ARIA specification.
