Gizmodo: “[January 1, 2020] isn’t just a day to nurse your hangover from New Year’s Eve—it’s also a day to celebrate the public domain. Movies, books, music, and more from 1924 are all entering the public domain today, meaning that you’re free to download, upload, and share these titles however you see fit. And it’s completely legal. Some titles from 1924, like the movie The Thief of Baghdad, already entered the public domain because there were stricter rules about registering copyright before the 1970s. If a copyright holder forgot to renew a copyright or put a mandatory copyright notice on their work, it could slip into the public domain accidentally.But there are plenty of other works that finally lose their copyright-protected status on January 1, 2020, like classic movies from silent-era comedians Buster Keaton and Harold Lloyd. There are also books from Thomas Mann and E. M. Forster, and an English translation of We by Yevgeny Zamyatin, a pioneering dystopian science fiction novel from the Soviet Union. Even George Gershwin’s song “Rhapsody in Blue,” one of the most famous songs of the 20th century, finally becomes public domain today. While the list below, inspired by the work of Duke Law’s Center For the Study of the Public Domain and the Public Domain Review, may not be comprehensive, it’s a good place to start.
If something was published in 1924 or earlier, it’s no longer protected by copyright as of today. And if you’re waiting for stuff from 1925 to become public domain you have to wait exactly one year. January 1, 2021 isn’t so far away…”
