"Whose woods these are, I think I”—whoa! We can’t quote any more of Robert Frost’s “Stopping by Woods on a Snowy Evening,” because it is still under copyright as this magazine goes to press. But come January 1, 2019, we, you, and everyone in America will be able to quote it at length on any platform.
At midnight on New Year’s Eve, all works first published in the United States in 1923 will enter the public domain. It has been 21 years since the last mass expiration of copyright in the U.S.
This makes me sad (not the new entries into public domain, that's awesome). Copyright is broken, far more concerned with milking art for every ounce of potential profitability than it is with cultural impact. It's amazing how little we care about our legacy, because our descendants will look back on us in the same way we look back on the worst of our ancestors.
