CC Publisher is a tool that does two things: it will help you tag your audio and video files with information about your license and it allows you to upload Creative Commons-licensed audio and video works to the <a href="http://archive.org/">Internet Archive</a> for free hosting. You also have the option of publishing the licensed and tagged audio works on your own site.
CC Lookup is a tool to verify embedded license information. MP3 files tagged with ccpublisher our CC Publisher application carry information about what license was chosen for the file and a public URL where the license can be validated. If you've downloaded an audio file from the Internet Archive or a P2P network like Morpheus that claims to be Creative Commons licensed, this application will verify that for you.
We have some extensions for Mozilla-based browsers (including Firefox), to enable viewing of Creative Commons licenses within your browser automatically.
