Open textbooks are way to significantly reduce student textbook costs while giving educators the flexibility to reformat and customize their course material. They are an affordable, flexible alternative to traditionally-published textbooks.
Open textbooks are available in both print and digital formats. Some contain supplemental materials (e.g., test banks, quizzes, PowerPoints, etc.). The open license attached to the textbook determines how it can be legally shared, altered, and remixed.
You can find examples by viewing a textbook in eCampusOntario’s collection. You can also find open textbooks elsewhere on the web. The most common repositories can be found here.
