Licenses for texts, media, and other content

Recommended: Public Domain

Once placed in the public domain, you work may be freely reproduced, distributed, transmitted, modified, or otherwise used by anyone for any purpose, commercial or non-commercial, and in any way, including by methods that have not yet been invented or conceived.

Peter St-Andre has an excellent essay, "Who's Afraid of the Public Domain?" that outlines the reasons to release your work into the public domain.

The Creative Commons Public Domain Dedication [CC-PD]

One way to release your work into the public domain is to visit the Creative Commons Public Domain Dedication Form, which will guide you through the process of placing your work under the Creative Commons "Public Domain Dedication." The form will ask you for your email, name, and title of work, and send you a confirmation email to verify your contact information. Then, it will autogenerate the license text for you along with instructions for how to include it in your work.

Creative Commons Attribution Share Alike license [CC-BY-SA]

This license lets others use, change, and share your work, even commercially, as long as they credit you with original creation and license new creations under identical terms. This license is often compared to open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use.

Creative Commons Non-commercial license [CC-NC]

This license lets others use, change, and share your work non-commercially, and although their new works must acknowledge you, they don’t have to license their derivative works on the same terms.
