Public Domain Media & Content: For Content Creators

You might consider releasing your work into the public domain, which allows anyone to use that work, any way they want, without requiring attribution to you.

To help facilitate that process, and to make it easier for content users to easily identify that work as in the public domain, Creative Commons offers a public domain mark (CC0 1.0) that can be applied to any work you want to dedicated to the public domain. They also offer a public domain dedication tool web form wizard that will generate the necessary mark image and language if you want to embed this into a website, blog, or LibGuide.
