BISG's EPUB 3 Support Grid was designed to be a handy reference to what enhancements and features of EPUB 3 render correctly on which devices, apps, and reading systems. It was created by industry experts representing leading publishers, service providers, and technology vendors through the auspices of BISG's Content Structure Committee. See below for a list of participating companies.

Recognizing the constantly shifting nature of digital publishing, the Content Structure Committee continuously updates the EPUB 3 Support Grid.

If you'd like to be notified when future updates are posted, email info@bisg.org with the subject line "EPUB 3 Grid Updates." Your email will be used only for these notifications.

We want to hear from you!

Industry feedback is critical to keeping the Grid accurate and up-to-date. We hope you'll join the dialogue and send in your comments and suggestions for improving and enhancing the Grid. Send your feedback to info@bisg.org.

NOTES ON THE GRID

---

• The EPUB 3 Support Grid is intended to provide a useful resource for publishers and their suppliers who would like to know the degree to which EPUB 3 is supported across various apps, devices, and reading systems.
• The EPUB functionality listed in Column B of the Grid is only a subset of what is currently available in EPUB 3. BISG's Content Structure Committee is tasked with ensuring the functionality tracked here is of importance to the general book industry.
• Information not provided by vendors of the represented reading systems and devices but instead provided by industry experts and users, is indicated as such on the Grid. BISG makes no claims to speak on behalf of vendors in these cases.
• Although best efforts are made to update the EPUB 3 Support Grid monthly, BISG does not claim it to be completely correct at any particular time. The Grid was most recently updated on November 19, 2012.
