www.creativecommons.org : Creative Commons is a nonprofit organization dedicated to building a globally-accessible public commons of knowledge and culture, making it easier for people to share their creative and academic work, as well as to access and build upon the work of others. Some of what they do:
- Provide Creative Commons licenses and public domain tools that give every person and organization in the world a free, simple, and standardized way to grant copyright permissions for creative and academic works; ensure proper attribution; and allow others to copy, distribute, and make use of those works
- Work closely with major institutions to ensure the correct use and implementation of CC licenses and CC-licensed content
- Develop technology like CC Search that makes openly licensed material easier to discover and use
