We are publishing today for comment our new Public Domain Mark, a tool that allows works already in the public domain to be marked and tagged in a way that clearly communicates the work’s PD status, and allows it to be easily discoverable. The PDM is not a legal instrument like CC0 or our licenses — it can only be used to label a work with information about its public domain copyright status, not change a work’s current status under copyright.
