There are a dizzying number of repositories for openly licensed materials. So where do you start? These are some of the most comprehensive repositories and federated search tools, and they're a great place to start your search.
Not all open content is made to be used in the classroom, but that doesn’t mean you can’t integrate them into your course. Open access book chapters and openly-licensed media can be great additions to your course.
