School librarians spend a vast amount of time chasing overdue books, especially when pupils have left school. So when Georgette Bordine, librarian at an Arizona secondary school, received two overdue books in the post 51 years after they were first taken out, she couldn't believe her luck.
The former pupil felt guilty about the time lapse and included $1,000 to cover the fines.
Ms Bordine, school librarian at Camelback High School, Phoenix, said that the borrower had moved to another state years before and the books had been misplaced.
She said the money would be spent on buying more books for the library, and the overdue books will be put back on the shelf.
