One way to increase visibility and access to your work is to share it with an existing community by publishing it on a content platform that has already enabled CC licensing. These sites make it easy for you to indicate the license on your work, along with other information, such as who to attribute. In addition, search engines like Google and Yahoo! will index your work as CC licensed if the metadata is properly attached.
The following are some major publishing platforms categorized by media type. You can also peruse more CC-enabled content directories. If your favorite community has not enabled CC licensing, you can usually indicate that you are using CC somewhere in an info box, or contact them and let them know it is a feature you would like to see.
