The Open Educational Resource movement is rapidly growing, and more materials are being created daily. Many have already been organized into large, searchable databases to make the process of finding OER easier. This guide is our effort to bring the materials straight to you. From the dropdown list under the "Resources by Subject" tab above, you will find pages where we have gathered just some of the many resources available in these subjects. If your area of study is not yet listed, simply check the more general links available from the Open Textbooks page to direct you to relevant materials. We hope you will enjoy your search for open educational resources.
