It's fun to be on vacation and go visit one of these. They're usually not in tourist areas and are likely to be in well established neighborhoods that a a different vibe than home. Also fun to read and come home with some random book that anchors you to that trip.
Just this morning I added several copies of books 1,2 & 3 of the Wheel Of Time series to a random Little Free Library because I had so much fun reading them and I hoped others would as well.
These are a great way to spread something you appreciate with the world. I once bought a stack of 30 or so well-used Calvin and Hobbes books and would regularly seed a few every now and then.

Do they have other names in different countries?
Hoping this continues.
