I’m, ‘You had to look up the library book you wanted on tiny paper file cards’ years old.
And sometimes you discovered when you asked for the book that those cards were not entirely right.
(I found a map in a book in a rare book collection doing research in college that the cars catalogue didn’t mention the book contained. Which also meant that few references about that book new about the map. To clarify this was a book printed in the 1500’s so not a lot of copies in any collection anywhere)
