Connexions is both a textbook repository and textbook authoring platform. If you are working with an open textbook from OpenStax College and want to modify the book, you should consider using Connexions as your publishing platform as it is the platform that the OpenStax College projects are built on.
In this video, you will learn how to use the Connexions platform to create a copy of an existing textbook hosted on Connexions, including the OpenStax College textbooks. You can then edit this existing collection and create your own customized version of an existing textbook.
