Would add my recommendation of The Kingdom of Coal. Have a lot of family history in those parts, and it really brought to life some of the legends. Also, there's a great book called Breaker Boys with (as I recall) many contemporaneous accounts.

As a non-sequitor, there's a train that runs in Allaire Village in Monmouth County, NJ (a wonderful state park) that carries a caboose used in the movie that Sean Connery (?) was in about the Molly Maguires.
