Creative Commons provides free, standardized copyright licenses that allow you to give permission for others to share & use your creative work, under the conditions that you choose. The benefit to creating a Creative Commons license for your work is that when others discover your work they know exactly how they can use, share, or modify it.
"Creative Commons licenses are not an alternative to copyright. They work alongside copyright and enable you to modify your copyright terms to best suit your needs." (Creative Commons, 2016).
Assigning a Creative Commons License to your work is easy. In-depth information is available on their website. If you need help, contact your librarian!
