Happy Public Domain day: for real, for the first time in 20 years!

Every year, Jennifer Jenkins and Jamie Boyle from the Duke Center for the Public Domain compile a "Public Domain Day" list (previously) that highlights the works that are not entering the public domain in America, thanks to the 1998 Sonny Bono Copyright Term Extension Act, which hit the pause button on Americans' ability to freely use their artistic treasures for two decades — a list that also included the notable works entering the public domain in more sensible countries of the Anglophere, like Canada and the UK, where copyright "only" lasted for 50 years after the author's death.
