ePub 3 with VitalSource specifications

eBooks in XHTML5 with Unicode-based fonts

VitalSource Technologies Inc. is committed to ensuring a rich reading experience for everyone through their multi-platform Bookshelf® reading system.
Bookshelf provides readers access to their content where and when they want – offline on Windows or Mac machines; online using standard browsers; and on mobile devices for iOS and Android.
A rich reading experience requires more than a device with the right version of Bookshelf.
We know that production of the highest quality content relies on consistent production standards and technology. That’s why VitalSource adheres to the EPUB 3 specifications defined by the International Digital Publishing Forum (IDPF). Conforming to the IDPF EPUB 3 Specifications ensures that consistency across operating platforms while enabling support of interactive elements and other features.
