What is an ePIB?

The ePIB format is Barnes & Noble's proprietary format, supported by Nook Color. It is a revised version of EPUB that readers can make use of for better interactivity–reading aloud passages, magnifying text, etc.

It is referenced in multiple ONIX code lists, such as:

• ONIX Code List 10 [Issue 36]

• ONIX Code List 175 [Issue 63]

Example:
