"This Pressbooks Guide was created to provide information specific to the creation and adaptation of open textbooks and other open educational resources (OER) using the authoring platform, Pressbooks. It is intended to act as an adjunct to the very comprehensive Pressbooks Userguide. Specifically, this guide addresses the issues faced by authors of open textbooks, most of whom are using versions of Pressbooks for which the PressBooks Textbook plugin has been installed"--BC Campus website.
