The European Network of Open Education Librarians organises a series of Workshops entitled "Embrace the Open" to learn collaboratively about some key Open Education topics. The slides and plan for the third "Embrace the Open" series workshop, "How the open textbook publishing kitchen works", are collected here. More resources are shared through additional links in the presentation. The recording of the workshop is available in the ENOEL Workshops playlist on our ENOEL YouTube Channel: https://www.youtube.com/@ENOELforOpen. Sylvia Moes (VU University, Netherlands), Margreet Nieborg and Mira Buist-Zhuk (University of Groningen, Netherlands), Lambert Heller and Simon Worthington (TIB - Leibniz Information Centre for Science and Technology, Germany) facilitated this workshop.
