A Creative Commons license is a human- and machine-readable copyright license that clearly indicates what rights the copyright owner retains and what rights the copyright owner offers to other users.
Creative Commons Licenses consist of some combination of four (4) basic elements. These elements combine to form six (6) CC license options.
Attribution or BY. All licenses include this element.
Non-commercial or NC. This designates that the work can only be used for non-commercial purposes (uses not intended for “commercial advantage or monetary gain”).
Share Alike or SA. This indicates that adaptations based on the work must be licensed under the same or compatible license.
No Derivatives or ND. This means that users cannot share adaptations of the work. (Users may make adaptations for private use but users may not distribute those adaptations.)
|CC BY or Attribution License. Others may use the work for any purpose with attribution given to the creator.|
|CC BY-SA or Attribution-ShareAlike License. Others may use the work for any purpose with attribution given to the creator; the adaptation must be licensed under the same or compatible license.|
|CC BY-NC or Attribution-NonCommercial License. Others may use the work for non-commercial uses only with attribution given to the creator.|
|CC BY-NC-SA or Attribution-NonCommercial-ShareAlike License. Others may use the work for non-commercial uses only with attribution given to the creator; the adaptation must be licensed under the same or compatible license.|
|CC BY-ND or Attribution-NoDerivatives License. Others may use the unmodified work for any purpose with attribution given to the creator.|
|CC BY-NC-ND or Attribution-NonCommercial-NoDerivatives License. Others may use the unmodified work for noncommercial uses only with attribution given to the creator.|
Copyright and CC licenses provide a range of “openness” to users. Licensors can choose how open or permissive a license to apply, from All Rights Reserved to Some Rights Reserved to No Rights Reserved (material dedicated to the Public Domain).
Users can combine material under different CC licenses, but with some caveats:
All Creative Commons licenses require that attribution be given to the creator of the content. Proper attribution allows the public to access the original work, identify the original creators, and know what license terms apply to specific content. The best practice for attribution is to follow the TASL approach:
An ideal attribution will follow the format:
“Day 2 (Tucson, AZ): University of Arizona Football” by Jamie Bernstein is licensed under CC-BY-NC-ND 2.0.
