What are the coziest libraries that you can visit in Pennsylvania -- especially around NEPA?

Sort of an odd question, but I'm looking for really cozy libraries I could visit in Pennsylvania - particularly in NEPA. It's hard to give a list of criteria, but it's a know-it-when-you-see-it kind of thing: Lots of little nooks and crannies in an almost mazelike layout, not very crowded, comfy chairs for long reading sessions (mostly tucked in out of the way places), just a bit cluttered-looking, maybe a fireplace, perhaps vaguely Victorian or otherwise old-timey in appearance.

I know there are a couple bookshops that shoot for that sensibility -- with varying degrees of success -- but are there Pennsylvania libraries that look and feel like that?
