 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).Originally aimed at self-publishing authors, in 2017 Pressbooks shifted its focus to work with universities on academic and textbook publishing.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.
