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. Vendors like Amazon and Lulu may be able to provide print copies of open texts, and they can be printed locally as well.
Anyone can always access digital copies of open textbooks for free. However, if you would prefer to read these texts in print, one option is to check a copy out from WSU Libraries. See this list of available print OER options, or print your own copy using a copy shop or service like Lulu.
