"Guardians of the Lost Library" is a 1993 comic book story made by Don Rosa for The Walt Disney Company, mentioned by Comics Buyer's Guide as "possibly the greatest comic book story of all time". Although afraid at the time of its creation of cramming too many historical details into the story, Rosa himself mentions in Uncle Scrooge #383 (November, 2008) that in fan mail he receives to this day, "Guardians of the Lost Library" to his own surprise is often referred to as "'the best Rosa story' or 'the best Duck story' or even 'the best comic book story' (?!!) that fans say they've ever read."
