While there is no one, standard definition of Open Educational Resources, UNESCO offers this:
"Open Educational Resources (OER) are teaching, learning and research materials in any medium – digital or otherwise – that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions."
OERs are typically:
- Free to access online
- Low cost to get a print copy
- Licensed by the author/creator with rights that are less restrictive than copyright (i.e. all rights reserved). This license typically (though not always) includes the right of any user to copy (digitally) & print the text as well as the right to adapt it as desired for use in a course, as long as authorship is attributed and use is non-commercial.
Open Textbooks are a type of OER that are designed to be a free or low cost alternative for a traditional textbook.
