George Washington returns overdue book 221 years late

The library at Mount Vernon, George Washington's estate in Virginia, replaced a copy of a book borrowed in October 5, 1789 by George Washington from the New York Library Society. The book in question was an influential book on international law, The Law of Nations by Emer de Vattel. Washington borrowed the book six months after being sworn in as the first President of the United States under the new Constitution.
