Copyright Resources: Creative Commons Licenses

What is Creative Commons?

Creative Commons is a nonprofit organization providing free, easy-to-use copyright licenses to create a standardized way to offer the public permission to share and use your creative work under specific conditions.

Public Domain

Public Domain materials are works that are free from intellectual property laws.  There are no restrictions for individuals to use these works, nor are permissions necessary. Works within the Public Domain can never be owned by any individuals. There are different ways that works become part of the Public Domain. These include: 

  • Expiration of copyright period (please see Cornell University's Copyright and Public Domain Guide)

  • Failure to comply with copyright formalities

  • Intentional dedication to Public Domain by the creator

  • Federal employees' works

  • "Common heritage of sources, or folk customs."

You can use any U.S. work in the Public Domain in any way that you want, as much as you want. They belong to the public. However, citation is still required for remixing and reusing public domain works. Additionally, keep in mind that copyright laws and designations of the public domain vary by country.

Resources for Public Domain can be found in Additional Resources.

Understanding Creative Commons Licenses

Creative Commons copyright licenses allow creators to retain their copyright while to granting specific permissions to others to share, use, and/or build upon their creative works.

To determine if Creative Commons licensing is right for you as a creator, or to understand how to interpret a Creative Commons deed for reusing works created by others, consult the following resources:
