If you wish to share them with the public in a way that makes them freely usable, you need to take explicit action to either declare them to be part of the public domain, or “license” them for use.
“Creative Commons” (CC) is a great mechanism to release your work, while still maintaining some ownership rights and control.
You do not have to submit your work to any agency to declare a CC license. All you have to do is mark your work as covered by a specific CC license.
With Creative Commons you can decide:
Choose a Creative Commons license: License Chooser
Any version of the CC licenses will allow us to post the material on the Open-ESL.org site.
If you are having trouble making up your mind, consider using this
