Underneath it says "(cardgames)". This is an area outside the library that will remain open, even after the library closes at 1am. It has smaller round tables, suited for playing card games. See what I did there?
We'll have a number of Tichu decks available on these tables for immediate use - no need to check them out of the library, but please take good care of them and I'd prefer they don't "walk away" so they can be used in future years as well.
Basically it's a concession to the Tichu community since no one has stepped up to run a tournament this year, as discussed here.
