Every country has its own copyright cutoff date. A copyright cutoff date is the year before which everything published in that country is automatically free of copyright. In the United States that year is 1923.
Before the internet, that year advanced by one year every single year. So, for instance, had that practice continued, then the cutoff year now would be something like 1930 or even later. But Congress stepped in and fixed a permanent cutoff date at 1923, with the aim of securing almost eternal rights to current copyright holders.
Other countries may have different cutoff dates. That's where the Magellan Project comes in. I personally don't know the cutoff dates for all other countries. If in your own wanderings you learn about the cutoff dates for other countries, or even find a table of all of them, please post here and let us know.
