The collection contains approximately 384 documents (deeds, titles, indentures, correspondence and leases) for anthracite coal lands, 40 envelopes, 20 maps, two pamphlets, one photogravure, and one large colored "painting." In general, the items are dusty, stained, crumpled, and some are very fragile.

The earliest date mentioned in the documents is 1773 (Tomlinson survey of land) referred to in a later dated deed to the most recent items from the Peca Coal Company dated 1962. The bulk of the documents are land exchanges mostly in the 1850s to the 1890s.
