OER include full courses, course materials, modules, textbooks, streaming videos, tests, software, and many other tools, materials and techniques used to support access to knowledge. Below are some examples of OER.

Open Textbooks

Open textbooks are the most visible and easily identifiable type of open resources available. Open textbooks are typically available online at no cost or can be purchased in a variety of other print and digital formats at a low cost, including hard bound copies. Below are two repositories of open textbooks.

Other Educational Resources

Open educational resources can include individual learning objects (like videos and graphics), entire programs of study, and everything in between: courses, workshops, lesson plans, web tools, lab assignments, test banks, and study guides. OER exist across almost all academic fields of study. The only requirement for OER is that they are available for free sharing and reuse among educators. The following sites search OER across repositories.

Open Courses

There are examples of full courses comprised only of OER. This may include additional tools or software that may require local infrastructure or payment, unless a free version is offered by the provider.
