Pressbooks is an open source content management system designed for creating books. It is based on WordPress, and can export content in many formats for ebooks, webbooks or print.[1]
Pressbooks is developed by Book Oven, Inc., a Montréal-based company founded in 2011 by Hugh McGuire (who also founded the audio book platform LibriVox).[1][2][3] Originally aimed at self-publishing authors, in 2017 Pressbooks shifted its focus to work with universities on academic and textbook publishing.[3]
The software is built on WordPress Multisite with modification of the admin and reader interfaces to reflect the intention of authoring books, a choice of themes for formating books, and to allow the export of books in print-ready PDF, mobi, ePub, and many other open formats.[4][5] It is available as a hosted service for self-publishers (pressbooks.com), supported institutional hosting (PressbooksEdu), third party hosts, or self-hosting of the software available from pressbooks.org.
