This presentation provides an overview of licensing and open educational resources (OER). It defines copyright and explains what is protected such as original works in a fixed medium. Creative Commons licenses are discussed which allow creators to select which copyright restrictions to waive so that others can legally reuse and remix the work. The most common CC license is Attribution (CC BY) which lets others distribute, use, and build upon the work. For educational resources to be considered fully open and reusable, they must allow for revision and remixing under an open license like CC BY. The presentation encourages using openly licensed OER to reduce costs for students and supports open education.
