My favorite example of the gap between copyright jurisdictions is P. G. Wodehouse. He died in 1975, but published a lot of work before 1925, including a great many Jeeves and Wooster stories. So in his home country, his work won't be public domain until 2046, but in the U.S. there's plenty of public domain material. There's a similar story with Agatha Christie.
