About 12 years ago I had checked out three books from the library and then moved. I packed the books away and never saw them again. I got a few notices in the mail and then nothing for a long time.
About two years later I got a letter from the CITY ATTORNEY saying that they were going to take legal action against me unless I ponied up my fine: $120. Forty bucks a book.
I paid. I just got a library card (from a different library) two weeks ago. My first card in years.
