The minimum standard for copyright term in the Berne Convention is life of the author plus 50 years. Of the 195 countries in the world, 181 are parties to the Berne Convention. Some countries go well beyond the minimum; in the US, it’s 70 years after the author’s death. Berne also introduced the concept that authors receive copyright protection the moment the work is “fixed,” and there’s no need to register for copyright or even put a copyright notice on the work. I don’t think having the year(s) listed matters anymore. What matters is the year of death of the author. (A morbid thought, I know.) Cheers, Ben
