Pennsylvania’s wages for librarians are just a few dollars away from the national average, but is great compensation for their cost of living rates. Even when their cost of living hovers a little above the average, it still makes more sense than earning too much but spending too much on living expenses elsewhere. Pennsylvania is also popular for its universities and colleges, so we know they have quite a lot of libraries there.
