Modifying an Open Textbook: What You Need to Know is actually two guides in one, the Quick Guide and a collection of Format Guides. The Quick Guide is for evaluating the open textbook you’d like to modify or edit, and determining how you’ll share the results of your work. The Format Guides are for getting started with editing common open textbook file and platform types. The truth is that while most open textbooks are legally licensed to be modified, the real-life work involved can sometimes be tough because of technical issues. We offer this guide as a way to help.
