PressbooksEDU is an online book/document formatting system that educators can use to create books that are accessible on all platforms: in print and digital, including all smartphones, tablets, ereader devices, and computers.

It enables anyone (faculty, staff, students) to produce professional, platform-agnostic outputs of educational resources in multiple formats: PDF (print and digital) | WEB | EPUB | MOBI | ODT| XML | WXR| XHTML.

Pressbooks is widely used to create open textbooks and OER, but it can also be used to create scholarly monographs, proceedings of symposia, grey publishing, course syllabi, dissertations, and more.
