Open Textbooks Defined

Open textbooks can be defined as "textbooks that have been funded, published, and licensed to be freely used, adapted, and distributed." Typically open textbooks are available as a pdf, epub, or set of html pages that are available at no cost to students and instructors.

True open textbooks are licensed so that they can be freely printed, distributed, and even adapted with correct attribution.
