Just stumbled upon this great animated video which may be helpful to instructors wanting to explore using open educational resources (OER) in their instructional material.  The first part of the video is really useful for people getting started with OER, and the second part gets into the details of combining open licenses while respecting the range of license terms.

The video was created by the good people at the Orange Grove repository, Florida’s digital repository for instructional resources.  Great work!  Here is their description of the video:

This video is intended to help you choose compatible resources and choose a valid license for your work. Suppose you are developing an open educational resource (OER), and you want to use some other OER within yours. If you create a derivative work by adapting or combining works offered under Creative Common licenses, you must not only follow the terms of each of the licenses involved, but also choose a license for your work that is compatible with the other licenses. Also available as “Creating OER and Combining Licenses Part 1” and “Creating OER and Combining Licenses Part 2.”
