Open Educational Resources at MDC: Overview: Finding OER

Open Educational Resources (OER) are "teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and re-purposing by others."

Open Textbook Collection

Open textbooks are free, online learning materials with Creative Commons licenses. Many of the collections will have links to the same books, but each will have a particular focus, and items you can't find in other collections.

Directory of Open Access Journals

The Directory of Open Access Journals was launched in 2003 at Lund University, Sweden, with 300 open access journals and today contains approximately 10,000 open access journals covering all areas of science, technology, medicine, social science and humanities.
