The goal of Creative Commons, according to its website, is "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."
1. What do Creative Commons licenses do?
Creative Commons licenses allow their holders to grant broad permission to others to share, remix, use commercially, or otherwise use their work without having to ask specific authorization for each use.
This makes it "easier for people to share and build upon the works of others, consistent with the rules of copyright." Lawrence Lessing, Stanford Law professor and founder of Creative Commons, is a long-time advocate of information freedom and copyright reform.
2. How do Creative Commons licenses interact with copyright?
Creative Commons licenses work alongside the rules of copyright, allowing you to authorize a more free usage of your work and choose the protection that best suits your needs. Creative Commons licenses apply to any work covered by copyright law.
- By using a Creative Commons license, you do not give up your copyright; you still own your work.
- Creative Commons licenses do not replace copyright registration—they apply in addition to copyright.
- Even if you're using a Creative Commons license, it is advisable to register your copyright so you can protect your work from unauthorized uses through the courts.
3. Are all Creative Commons licenses the same?
No. Creative Commons offers six different licenses, each allowing different uses of your work:
- Attribution: The most permissive Creative Commons license allowing others to use, distribute, remix, tweak, and build upon your work—even for profit—so long as you are given credit for the original in the way you request.
- Attribution Share Alike: Very similar to the Attribution license. You permit others to use, distribute, remix, tweak, and build upon your work—even commercially—provided you are given credit in the way you request for the original, but this license also requires the user to license all new creations under identical terms (meaning any new creations may also be used for profit); this is often compared to open source software licenses.
- Attribution No Derivatives: Permits others to redistribute—including commercially—your work so long as you are credited in the way you request and the work remains whole and unchanged.
- Attribution Non-Commercial: Allows others to use, distribute, remix, tweak, or build upon your work non-commercially so long as you are given credit in the way you request. Derivative works do not have to carry the same license (meaning future derivative works can be commercial).
- Attribution Non-Commercial Share Alike: Permits others to use, distribute, remix, tweak, and build upon your work non-commercially so long as you are given credit in the way you request and the new works are licensed under the same terms.
- Attribution Non-Commercial No Derivatives: Closest to traditional copyright, this is the most restrictive Creative Commons license and allows others only to redistribute your work non-commercially so long as it remains unchanged and you are given credit in the way you request; often called "free advertising" because people can download and share your work freely.
Each specific Creative Commons license has its pros and cons depending on your situation, but the biggest overall pros to Creative Commons licenses are that they are free and rather easy to use. You simply go to the Creative Commons website to decide which license meets your needs and then attach the appropriate symbol to your work.
Creative Commons licenses also encourage others to use and redistribute your work, which can create publicity for you.
The biggest con in using Creative Commons licenses is that in all but the two most restrictive licenses, you grant permission to use your work ahead of time, so you can never be sure who is using your work or making money from it.
Any content licensed under Creative Commons can be used by others without compensating you for the use. However, Creative Commons licenses are non-exclusive, so you can still license the same content under a different agreement if you choose.
5. Who uses Creative Commons licenses?
The music industry, especially aspiring artists, are particularly drawn to Creative Commons licenses because of the prevalence of remixing and "mash-ups," which are great ways for new artists to gain exposure. Many of the licenses also allow an artist to keep her options open if she isn't sure what she'll want to do with her work in the future.
Bloggers and other online presences are also increasingly turning to Creative Commons in the spirit of share and share alike into a voluntary public domain.
