Happy contrafactual public domain day (what you've lost) - Boing Boing:
Jennifer Jenkins sez, "What could have been entering the public domain in the US on January 1, 2012? Under the law that existed until 1978... Works from 1955. Asimov's The End of Eternity, Nabokov's Lolita, the play Inherit the Wind, Hitchcock's To Catch a Thief, Disney's Lady and the Tramp, Rebel Without a Cause, The Seven Year Itch, the music for Blue Suede Shoes and Tutti Frutti, and Laurence Olivier's film version of Richard III... What is entering the public domain today? Nothing."
