And if you're a pirate, or if you happen to have a lot of Audiobook CDs, or if you have a bunch of books on audible and want to free them, AudiobookShelf is an amazing self hosted solution for Audiobook libraries
Libby! They also loan out ebooks (which is usually what I use it for). Total game-changer.
Also, as a tip: Check out what libraries you're eligible to join. I'm in New York State, and despite not living in NYC, I am totally eligible for cards at the New York Public Library, Queens Public Library, and Brooklyn Public Library. Between those, and all the libraries in my county pooling their resources, I rarely have to wait long for a book unless it's brand new.
Yeah, it works great! Odds are you might have some libraries that are open to everyone in your county or even your state (assuming you live in the US, but I don't even know if or how Libby would work elsewhere). There are also libraries that are open to anyone in the country, though they seem to be closing that option. And there are some libraries that will give cards to non-residents for a recurring fee.
...and you didn't hear this from me, but you can also, you know, lie. Use a realty website like Realtor.com or Zillow, get a valid address, and sign up for some libraries. Very rarely one will check your IP, but otherwise, you know. I haven't had to do it because I'm spoiled as a New Yorker, but it's an option.
