Some people might welcome polite interest on what they're reading, but it's a big grey area. Most people are interested in talking to other fans, but it is a quiet place for reading so there's the risk of interrupting people when they're in the middle of the best part. I don't think it would be weird to talk to someone reading a book you loved while they pause to look out a window or stretch.
I've never known anyone to go to a library to socialize, but there's no rule saying you can't talk and see what happens.

I think meeting a person at a library might be difficult because social rules are even more complex there. Finding "the right time" to approach someone is pretty hard for most aspies in general... library etiquette might just get in the way.
But if you see someone reading a book/who shares an interest with you, I'd try coming up to them and simply introducing yourself and your connection to that book/interest. It's a library, and you're unlikely to see that person again. Especially not at a party or anything.
Yep... easy to disrupt other people, too.
