Most OERs are licensed in a way that allows users to access, share, and remix the resources. The most common type of OER licensing is Creative Commons (CC) Licensing. CC licensing allows a creator to change to copyright of a work from "all rights reserved" to "some rights reserved." Creative Commons licensing affords the user versatility while licensing, allowing them to customize the license to varying levels of openness. For example, most licenses require users to provide credit to the original creator, but some may add the stipulation that you cannot reuse or remix the OER for commercial purposes.
