Introduction to Creative Commons and their licenses

Created by Creative Commons (CC), a non-profit organization, each of the six CC licenses grant readers specific rights regarding how the open access research can—and can’t—be used. Adding to the need for understanding is the fact that some institutions mandate that the research they fund be published under specific CC licenses. Choosing the CC license under which your research is published is one of the more important decisions an author can make during the publication process.

CC licenses and the rights they grant

Below is a summary of the rights granted by each of the CC licenses. The list is sorted from the most permissive license to the most restrictive license.

CC BY: The most permissive CC license. This license lets others distribute, remix, adapt, and build upon your work, even commercially, as long as they credit you for the original work.

CC BY-SA: This license lets others distribute, remix, adapt, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms.

CC BY-NC: This license lets others distribute, remix, adapt, and build upon your work. Their new works must acknowledge you and be non-commercial, but they don’t have to license their derivative work on the same terms.

CC BY-NC-SA: With this license, readers can distribute, remix, adapt, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms.

CC BY-ND: This license allows others to copy and distribute your work—commercially and non-commercially—as long as it is passed along unchanged and in whole, with credit to you.

CC BY-NC-ND: The most restrictive CC license. This license allows others to copy and distribute your work and share them with others as long as they credit you, but they can’t change the work in any way or use it commercially.

Two final points for authors to remember

1. The CC license you apply to your work cannot be revoked—so, choose carefully!
2. You must own or control the copyright for the work—only the copyright holder can apply a CC license to a copyrighted work
