The Walter C. Woodman photographs and research notes series contains materials about iron furnaces. The series has been divided into two subseries: Iron furnaces and Saugus Iron Works. The Iron furnaces subseries consists of two volumes of notebooks compiled by Woodman which contain newspaper clippings, correspondence, field notes, programs and maps about the early iron industry and furnaces in Connecticut, Maine, Massachusetts, New Jersey, New York, and Virginia. There are three photograph albums containing Woodman's photographs of furnaces which correspond to his research notes. There is one report from the American Society of Mechanical Engineers which chronicles the organization's history and the history of iron Forges, furnaces and rolling Mills in New England. The publication was edited and partially written by Woodman. The work was published posthumously and is dedicated to Woodman.

The Saugus Iron Works subseries is made up of correspondence, articles, and booklets which document the nomination of the Saugus Iron Works site as a National Historic Mechanical Engineering Landmark, it's acceptance, and planning for the dedication. All of which Woodman played an instrumental role in.
