Open Access Agreements and Memberships

Licensing your work

Open licenses exist to help authors share their work for others to use, while still retaining the rights. Creative Commons licenses are free, easy to use licenses that copyright holders can apply to any type of copyrighted work. By using a Creative Commons license, the copyright holder is permitting others to reuse their work as long as they are properly credited. Using a Creative Commons license is as simple as choosing a license and labeling the work with the license title or icon. There are six Creative Commons licenses available that provide various permissions of reuse.

What Creative Commons Licenses Do

By using a Creative Commons license on a copyrighted work, others are able to reuse the material without explicit permission. This provides benefits to both the copyright holder and the user: the work is easier to reuse, allowing for the work to have potentially higher impact, and it is immediately clear to the user how they are able to reuse the work.
