Thankful I did not have to worry. The K12 program introduces the card catalog as point of history and moves on to a digital exercise of how to search in the library. But in the interest of due diligence I wanted to actually show my child an actual card catalog. Easy? No. There is not one in the whole county. Even the historical small libraries are digital. They only place we can find one is downtown at the Library of Congress.
We did find a movie on Brain Pop Jr. and YouTube about the card catalog. Enjoy!
