This will vary a lot of course, but in a lot of cases your local library may not be just your local library.

The library in my town isn't anything too special, it's a little small and doesn't really have a lot of the cool things people talk about libraries having these days (though I am occasionally surprised, they have mobile hotspots you can borrow for example)

But it's part of a network of libraries from around my county, so I can go check things out of around 30 different libraries and some of those other branches have a lot more cool stuff than mine does
