Haha, but seriously - never call 911 except in an emergency. It’s terribly annoying to lose a card, but the library will issue you a new one.
You can call 911 for help locating your lost Library Card or You can go to the Library that issued your card and ask them for a New Library Card? Wow Bevis & Butthead could have answered that Question For You lol.
