52,560,000 Minutes Late

This contrasts with the advertised tardiness, which was a mere 40 minutes.

Note: I did a quick calculation, in which I assumed 100 full years; this gives an estimate of 52,596,000 minutes. The article didn't indicate even the month in which the book was checked out. In my calculation, I took 100 years, 365.25 days per year, 24 hours per day, and 60 minutes per hour.
