How to Create Attributions for Open or Public Domain Works

CC Licenses

CC BY logo

Creative Commons-Attribution, CC BY

This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.

CC BY Share Alike SA logo

Creative Commons - Attribution - ShareAlike, CC BY-SA

This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.

CC BY No Derivative ND logo

Creative Commons - Attribution - No Derivatives, CC BY-ND

This license allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to you. This means no edits or changes to the original work.

CC BY Non-Commercial NC logo

Creative Commons - Attribution - Non-Commercial, CC BY-NC

This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.

CC BY Non-Commercial Share Alike NC SA logo

Creative Commons - Attribution - Non-Commercial - ShareAlike, CC BY-NC-SA

This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms.

CC BY Non-Comercial Non-Derivative NC ND icon

Creative Common - Attribution - Non-Commercial - No Derivatives, CC BY-NC-ND

This license is the most restrictive of the six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.

What's the Public Domain?

Public domain licenses

CC0 public domain Creative Commons Zero logo

Creative Commons Zero, CC0

Otherwise known as "No Rights Reserved," this type of public domain is when creator(s) has waived their rights to the works and gifted their work to the world. Use this universal tool if you are a holder of copyright or database rights, and you wish to waive all your interests that may exist in your work worldwide. 

Public domain No Known Copyright logo

Public Domain

Otherwise known as "No Known Copyright," this enables works that are no longer restricted by copyright to be marked as such in a standard and simple way, making them easily discoverable and available to others. Many cultural heritage institutions including museums, libraries and other curators are knowledgeable about the copyright status of paintings, books and manuscripts, photographs and other works in their collections, many of which are old and no longer under copyright.
