Thanks to my Creative Commons instructor, Maran Wolston, I made a slight edit to my description of Collections below. I hope this serves as a pretty good explanation on the difference between a remix and a collection under Creative Commons licensed works.
This is one of my videos explaining the difference between Open Access and OER to students. It was one of my assignments for the Creative Commons Certificate for Librarians course in fall 2018. While it is long, I am still going to keep it and may make it available to students who are interested in how the publishing process works and how they can access and be a part of the Open Education movement.
