Glenn Fleishman, The Atlantic:

The Great American Novel enters the public domain on January 1, 2019—quite literally. Not the concept, but the book by William Carlos Williams. It will be joined by hundreds of thousands of other books, musical scores, and films first published in the United States during 1923. It’s the first time since 1998 for a mass shift to the public domain of material protected under copyright. It’s also the beginning of a new annual tradition: For several decades from 2019 onward, each New Year’s Day will unleash a full year’s worth of works published 95 years earlier.

This coming January, Charlie Chaplin’s film The Pilgrim and Cecil B. DeMille’s The 10 Commandments will slip the shackles of ownership, allowing any individual or company to release them freely, mash them up with other work, or sell them with no restriction. This will be true also for some compositions by Bela Bartok, Aldous Huxley’s Antic Hay, Winston Churchill’s The World Crisis, Carl Sandburg’s Rootabaga Pigeons, E.E. Cummings’ Tulips and Chimneys, Noël Coward’s London Calling! musical, Edith Wharton’s A Son at the Front, many stories by P.G. Wodehouse, and hosts upon hosts of forgotten works, according to research by the Duke University School of Law’s Center for the Study of the Public Domain.
