George Washington’s very, very late library books.

In this article, about a different late library book, these two paragraphs:

In April 2010, the New York Society library did an audit of its records and found that a book on the Law of Nations and a volume of House of Commons debate had been taken out on 5 October 1789 and never returned.

The borrower was George Washington who famously never told a lie but clearly had other faults. He theoretically owes the library, the oldest in New York, over $300,000 (£195,000) in fines.
