The teaching, learning, and resource materials of OER Commons reside in the public domain or have been released under an open license that permits no-cost access, use, and redistribution by others with no or limited restrictions. These privileges can not be revoked as long as you follow the license terms.
Watch for the license symbols listed below.
No Strings Attached
No restrictions on your remixing, redistributing, or making derivative works. Give credit to the author, as required. Includes Public Domain, Creative Commons Attribution (CC BY), Creative Commons Public Domain, and any item that explicitly says no restrictions.
Works in the public domain are those whose exclusive intellectual property rights have expired, have been forfeited, or are inapplicable. This license allows you to distribute, remix, tweak, and build upon public work, as long as you credit the original creator.
This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.
Remix and Share
Your remixing, redistributing, or making derivatives works comes with some restrictions, including how it is shared. Includes Creative Commons Attribution Share Alike (CC BY-SA), Creative Commons Attribution NonCommercial Share Alike (CC BY-NC-SA), Creative Commons Attribution NonCommercial (CC BY-NC), GNU Free Documentation License (GFDL), WGBH Teachers' Domain remix.
This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.
This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.
Your redistributing comes with some restrictions. Do not remix or make derivative works. Includes Creative Commons No Derivatives (CC ND), WGBH Teachers' Domain share.
