Creative Commons is a nonprofit organization that aims to increase the amount of creativity (cultural, educational, and scientific content) in “the commons” — the body of work that is available to the public for free and legal sharing, use, repurposing, and remixing.
Creative Commons tools give everyone from individual creators to large companies and institutions a simple, standardized way to grant copyright permissions to their creative work. The Creative Commons licenses enable people to easily change their copyright terms from the default of “all rights reserved” to “some rights reserved.”
The aim of the CORE-Materials OER project is to make a significant number of the many existing electronic learning resources in Materials Science and Engineering freely available online under a range of Creative Commons licences.
For a quick intro to Creative Commons, check out this short video, entitled "Wanna Work Together?"
