The Center for Public Integrity’s year-long investigation into the social and environmental impacts of longwall mining centered on hundreds of pages of documents obtained from government sources, such as the Pennsylvania Department of Environmental Protection and the U.S. Fish and Wildlife Service; legal agreements between coal companies and property owners; environmental studies; landowner letters; and federal and state records requests.

The library features key documents exemplifying key people or issues in each of the project’s magazine articles.
