Happy Public Domain Day Everyone! This is a momentous occasion as this is the first year since the 1978 Copyright expansion that the US has actually had one of these. Today, the first works from 1923 will enter the public domain in the US and it is a bittersweet moment for everyone who cares about the progress of art and science. Sweet for the wonderful works that people will be able to distribute freely without risk of being sued or jailed for doing so. Bitter for all the works that have been lost because the owner of the copyright didn’t care about preservation or because the copyright owner cannot be found.
