The Coxe Family Mining Papers were donated to HSP by the Coxe family in 1967. From 1999 to 2001, with funding from the National Historical Publications and Records Commission and the Pennsylvania Historical and Museum Commission, these important records were organized, described, and preserved. The collection, consisting of more than 1,000 boxes and upwards of 300 volumes, richly documents the history of what once was the largest independent anthracite coal producer in the United States.
