An Overview of OER

4 Open Licenses

Open licenses make OER possible.[1] Open licenses enable creators to proactively communicate to the public about how copyrighted material can and cannot be used. Open licensing options fill the gap between “all rights reserved” copyright, which protects everything from storing copies of a work to modifying the work, and the public domain, in which there is no copyright protection. In this chapter, you will learn how popular open licensing mechanisms, such as Creative Commons (CC), enable creators, remixers, and content users to quickly and easily understand when we can legally use and adapt the work of others.

Copyright (all rights reserved) on left of spectrum requires permission from owner for reuse; Creative Commons (some rights reserved) in center permits reuse without permission under specifications shared in license; public domain (no rights reserved) on right may be used without permission.

Creative Commons Licenses

There are six major CC licenses that all include different combinations of the four basic requirements described below.[2]

  Attribution

You let others copy, distribute, display, and perform your copyrighted work—and derivative works based upon it—but only if they give you credit the way you request. This element is a part of all six licenses.

  Non-Commercial

You let others copy, distribute, display, and perform your work—and derivative works based upon it—but for noncommercial purposes only.

  No Derivatives

You let others copy, distribute, display, and perform only exact copies of your work, not derivative works based upon it.

  Share Alike

You allow others to distribute derivative works only under a license identical to the license that governs your work.

The six licenses and the Creative Commons Public Domain designation are shown below in order of the amount of freedom they provide for users. The spectrum includes two licenses that are not OER because they do not allow for revision and remix (i.e., CC BY-ND and CC BY-NC-ND).

The CUNY OER representative at your campus can help you determine which open license will give you the type of ownership you want, while still allowing your work to be reused and remixed freely.
