Recently, a new set of Quick Links about ebooks were added to BuyAccessible.gov. Quick Links contain solicitation language and a Government Product Accessibility Template (GPAT) for a specific deliverable, in this case an ebook. There are also Quick Links for ebook readers and ebook software.
The GPAT for ebooks will let you know what Section 508 technical provisions most likely apply to ebooks. For example most of the provisions in Section 1194.22 Web-based intranet and Internet information and applications apply. You can use this information to include in your solicitation requirements when making a purchase, or in your design requirements when creating an ebook.
