Reports, studies, and pamphlets series is arranged into three subseries: Research and comments about Woodlawn and studies prepared for the Woodlawn Trustees; Materials relevant to conservation and preservation of open space; and Material relevant to conservation and preservation.

Research and comments about Woodlawn and studies prepared for the Woodlawn Trustees subseries contain print materials that Woodlawn commissioned to chronicle important people, places, deeds, and events in the history of Woodlawn. Board members and Woodlawn's "neighbors," from time to time, needed chronological clarification of Woodlawn's mission and future expectations. There are reports written by professional information specialists, using board minutes, letter books, and historical correspondence to tell the story of Woodlawn for the company's future officers and employees. This subseries includes materials about the Quaker faith written by those who influenced early trustees. Additionally, there is the inclusion of a forestry study by Thomas White commissioned by Woodlawn in which White examines the forests of Woodlawn property and produces an economic analysis and other reports.

Materials relevant to the conservation and preservation of open space subseries are documents that would enhance the Woodlawn Trustees' understanding of better ways to preserve and conserve open space for the benefit of the general public. This subseries comprises print materials best describing various aspects of the preservation and conservation of open space and orderly urban and suburban planning.

Materials pertaining to zoning and miscellaneous reports subseries consist of documents about the New Castle County Department of Planning, development and zoning plans, Hagley Museum and Library archival information, and history of specific landmarks in Delaware.
