“The move has a practical effect: It extends the copyright from Jan. 1, when it is set to expire in most of Europe, to the end of 2050. Copyrights in Europe generally end 70 years after an author’s death. Anne Frank died 70 years ago at Bergen-Belsen, a concentration camp, and Otto Frank died in 1980. Extending the copyright would block others from being able to publish the book without paying royalties or receiving permission.”
