Published since the 1870's this report contains production statistics, mine names, locations, owner information, and accident statistics. Prior to the mid-1880's the reports for anthracite and bituminous coal were produced by separate agencies, therefore early reports for bituminous coal are available as part III "Industrial Statistics" of the Annual Report of the Bureau of Statistics of Pennsylvania, later the Annual Report of the Secretary of Internal Affairs of the Commonwealth of Pennsylvania. Industrial minerals were included in these reports beginning with 1973.

Another report "Pennsylvania Minerals" was issued in 1955, a report of a joint commission, which covers the period from approximately 1943-1953. The presentation of the report to the legislature appeared in the Pennsylvania Legislative Journal in 1955 (appendix p.9797-9542).
For information about mining activities prior to 1870, sources are limited. I suggest consulting the following:
