It's FREE and depending on your local library system, having a library card also comes with:
- Hoopla: Lets you stream movies and check them out FOR FREE
- Libby: E-book collections so you can read books/magazines/etc for FREE
- Equipment rentals: Some libraries in my hometown have game consoles/musical instruments/etc that patrons can check out
And a bunch of cool stuff
The more active patrons there are, the more likely they'll keep their funding! Basically, support your local library! Get a card! Use the services!
