That funny word in the title would be the German word for a library fine. It literally means something like "Missed deadline Fine". I forgot to return a book and had to pay 3€. The book was "The Long, Dark Tea-Time of the Soul" by Douglas Adams, and I think he would have approved of my disorganisation. Certainly none of his characters would have gone to the terrible effort of returning a book to the library just because they'd finished reading it. I wonder what, normalised to the number of times it has been borrowed, the most overdue book of all time is.
