Despite our best efforts, spelling errors and other errata are sometimes included in the published legal code for licenses. Creative Commons publishes SHA1 checksums for legal code, which allows people who receive a copy of the license to easily verify this it has not been tampered with. Therefore Creative Commons does not amend legal code once published.

Creative Commons is planning an errata service which will allow us to record and report the typographical errata for a license without modifying the document itself. This service is currently under development, and will launch Q3 2007. Until that time, this wiki page collects known errata for license legal code. If you discover a spelling error on a license, please record it here. The information on this page will be integrated in the errata service at launch time.
