As someone who spends a lot of time in coffee shops (working, reading studying), the library is a nice change of scenery and you don't have to buy anything to justify taking up space. A lot of libraries are stunning too.
Also they get you access to audiobooks which are a great alternative to paid subscriptions. I do have a libro.fm account though to support my local indie bookstore.
This is great! Many things I didn't think of...
My mind was blown when I realized my library gives you $3/day of free printing (@10c/page). I will never pay to print anything again, since I mostly have random 1 off things to print every once in a while.
A library where I used to live in PA kept small household tools and appliances for checkout. Great for when you need a Kitchenaid mixer three times a year.
TL;DR
Also rent DVD and Blu ray discs for free
Or access to free streaming of movies
And video games, including new titles, if you don't mind potentially waiting just a little.
