My wife is a library administrator here in Indiana. Libraries are amazing. Aside from all of the free books, movies, music, audiobooks both physical media and streaming and ebooks, this is what our public library offers. This is a small city and this is not unusual for public libraries:
Free internet with a computer lab. You don't even need a library card.
Board games and TTRPGs available for loan.
Free 3D printing.
Free laser cutting and engraving.
Games for multiple consoles.
An HTC Vive headset, a PS4 and an XBox for the teen room (although adults can use them too).
A playroom for babies and toddlers with all kinds of toys and things to climb on.
Kits you can take home to learn things like how to play the ukulele or how to crochet.
And, of course, like most libraries, meeting rooms for anyone to use.
A new branch is being built in another part of town and it will have a room with a lockable door and a sign-up sheet. One person will be allowed in at a time. Inside will be a washer, a dryer and a shower, all free to use.
On top of all this, the library is also willing to make deliveries to your home for free once a month if you can't make it in or just don't want to.
Librarians are also living Wikipedia/web Searches. They will happily look up any information for you that you could possibly ask. They will do all the research they can to help you. That's part of their job and part of what they went to school for- did you know librarians are generally expected to have masters degrees in library science?
Public libraries are fucking incredible. They are not just for poor people or homeless people or whatever silly thing people might think about them. Go in and check out the one in your area. You don't need a card to get in. You may not need a card to use a single service while you're there. You might only need a card to take things out or use online services.
Where I am we also have state libraries and a national library. I haven't fully explored either of them, but the most useful thing I've found they have are a shit ton of records and newspapers. My state library has soooo many records.its truly mind boggling. The national library has digitised about the same amount of newspapers and gazettes as the entire population of my country. They also keep almost the same amount of records just relating to Australia (or "of interest" to Australians) as the entire population of the planet
Exactly the same with the library here. Tons of local records archived. People come in to do genealogy research all the time.
