"Singin' in the Rain"? The title track from the hit play and movie entered the public domain Wednesday alongside a bevy of other songs, characters and literature first published in the mid-1920s.

It’s a new year, and that means more works are headed to the public domain. This year, thousands of copyrighted works created in 1929, including the earliest versions of Popeye and the Belgian comic book character Tintin, are now free to reuse and repurpose in the US.

But now, a very specific and famous work of art has entered the public domain, the brilliant 1929 novel by Ernest Hemingway, A Farwell to Arms. This was Hemingway's fifth published book overall, and his third novel.

Last year, the original version of Mickey Mouse went into the public domain. That doesn’t mean that anyone can use Mickey Mouse’s image for whatever they want, but it does mean that the version of Mickey who first appeared in Walt Disney’s original Steamboat Willie cartoon is now fair game.

Public Domain Day, meaning artworks from 1929 (or 1924 in the case of sound recordings) are now free for all creators to use and abuse to their hearts' content. The works of art, music, literature, and film now entering the public domain will be yours,

Walt Disney directed the iconic Skeleton Dance short animated by Ub Iwerks, as well as when Mickey Mouse starred in his first talkie. The intrepid Tintin and original Popeye characters have arrived in the public domain as well.

More work from major writers, directors and musicians — along with legendary characters — entered the public domain to start 2025.
