Robin, a U.S. citizen, has copyrighted her book in the United States. She would now like to copyright the book in Bolivia and Brazil, members of the Berne Convention. If those countries afford their nationals a copyright term of protection for the author’s life plus 50 years, what will the term of protection be for Robin’s book in Bolivia and Brazil? What principle governs your answer? May those countries require Robin to place a copyright notice on her book?
