I understand that Adolf Hitler's copyright in "Mein Kampf" was acquired by the state of Bavaria, who use it for suppressing the book. If and when the copyright expires (2015 if the duration is not further extended; in many EU countries copyright was extended from 50 to 70 years in 1995, with the effect that "Mein Kampf" was out of copyright for 3 months before disappearing for another 20 years) it will be interesting to see whether Bavaria tries to use moral rights to further suppress the book, arguing that in this day and age Adolf Hitler certainly wouldn't want to be associated with a book that promotes fascism!
