EPUB: Accessible Electronic Documents

EPUB® 3 defines a distribution and interchange format for digital publications and documents. The EPUB format provides a means of representing, packaging and encoding structured and semantically enhanced Web content — including HTML, CSS, SVG and other resources — for distribution in a single-file container. This specification represents the second major revision of the standard.

EPUB 3 has been widely adopted as the format for digital books (ebooks), and this revision continues to increase the format’s capabilities in order to better support a wider range of publication requirements, including complex layouts, rich media and interactivity, and global typography features. The expectation is that the EPUB 3 format will be utilized for a broad range of content, including books, magazines and educational, professional and scientific publications.
