      Actually, most librarians would be unaware of the existence of this card file. I didn't know it existed before I first visited the Library of Congress (many years ago), even though it's used to add Dewewy numbers to records used around the world.

      But it's not a catalogue: it's an authority file, used by cataloguers & classifiers to create catalogue records. And it might be converted to machine-readable form in the near future, as must card catalogues and authority files have been.
