The Pennsylvania Mining Resources page contains lists and links to publications related to the mineral resources and mining history of Pennsylvania. Items include materials from the Pennsylvania Geological Survey, the Pennsylvania Department of Environmental Protection, and other sources. Of particular note are the inclusive Pennsylvania Annual Report of Mines for the period 1870 to 1979 and the Historical Statistics of Pennsylvania’s Mineral Industries.

The Bituminous coal mine maps of Pennsylvania were created by the Works Progress Administration from 1934-1938. Workers transcribed information about the extent of underground bituminous coal mines on to these maps, as well as locations of oil and gas wells. Although some mine information was never transcribed, this set provides an excellent representation of the extent of mining throughout western and central Pennsylvania.The counties covered include Allegheny, Armstrong, Beaver, Bedford, Blair, Bradford, Butler, Cambria, Cameron, Centre, Clarion, Clearfield, Clinton, Elk, Fayette, Forest, Fulton, Greene, Huntingdon, Indiana, Jefferson, Lawrence, Lycoming, Mercer, Somerset, Sullivan, Tioga, Venango, Washington, and Westmoreland.

The Pennsylvania Mine Map Atlas is a collaborative of the Pennsylvania Department of Environmental Protection (DEP) and Penn State’s Pennsylvania Spatial Data Access Program (PASDA). This Web-based mapping application and downloadable data allow residents and stakeholders to see detailed underground mine maps that were once only available in hard copies. It not only allows homeowners to view previously unavailable mine maps, but also allows them to see their home’s proximity to the nearest underground mine.

Links to PDF versions of Pennsylvania coal mine accident registers, providing documentation on mining accidents for the commonwealth's anthracite and bituminous coal districts. Topics covered in both the early and later reports include: name of the inspector, name of mine, operator of the mine, name of the injured miner, mine district number, date of the accident, cause of accident, county in which the accident occurred, whether fatal, whether the accident occurred inside or outside the mine, citizenship status, nationality, job classification, marital status, and the number of children.

This collection consists primarily of a special report by the Pinkerton National Detective Agency from its investigation of the Scranton, Pennsylvania general strike of 1877. In response to increasing labor unrest in the post-Civil War period, several corporations in the mining, railroad, and steel industries hired the Pinkerton agency, which Allan Pinkerton had founded in 1850, to surveil, infiltrate, and undermine labor organizations and break strikes.

The Thomas Richards (T.R.) Johns papers digital project offers a unique historical resource to examine life, work, and community within the central Pennsylvania bituminous coal mining region.
