I'm in the UK and these are all over the place, especially in more rural areas, and we're famed for our lovely weather! 😂

I live in SW Finland on the coast of the Baltic Sea. It's wet and cold 90% of the year.

We still have this sort of book exchange in the entrance way to my local shop. A tiny bookshelf/night desk. Not too common though, I can't think of any others right now.

But like the weather shouldn't be the issue, that's just an engineering problem at that point. I imagine like a glass doored fridge with some dehumidifiers placed inside should probably work in most places to protect books.
