Happy Public Domain Day...

...er, yesterday:

It is January 1st, which means that this morning at midnight a batch more “life-plus” copyrights expired in those countries — most of them — where copyright expires at the end of the Nth year following the death of the author.

Yes, folks, it’s Public Domain Day! And it’s international! There are little Public Domain Day virtual commemorations going on in places like Poland and Switzerland. Spread the word!

In the life+50 universe, which constitute the largest cohort of countries, including Canada, which collectively have the majority of the world’s population, life-plus copyrights expired at midnight for those authors, or last-surviving of multiple authors, who died in 1958.
