The following resources can be used to locate high quality, peer-reviewed open textbooks in a variety of subject areas. Most of these resources also provide evaluative information about the textbooks they contain, such as faculty reviews, accessibility reviews, and usage statistics.
Other open educational resources (syllabi, course handouts, lesson plans, etc) can be found in the following OER repositories. Some, like OER Commons, contain open textbooks as well as other course materials. Others, like Open Learn, host live course content and provide users with "badges" to indicate if they have completed a course.
