'Winnie the Pooh,' 'Sun Also Rises' among works going public in 2022

I am guessing that the popularity of 'Winnie the Pooh' has taken a hit in recent years.

The long U.S. copyright period adopted in recent decades has meant that many works that would now become available have long since been lost, 

This is why the US copyright laws are too long. They should be shortened to 50 years.
