The Frederick S. DeMarr Library of County History specializes in many different types of materials relating to Maryland, with particular emphasis on Prince George’s County. It began as the private collection of Frederick S. DeMarr, and was legally conveyed to the Historical Society after Mr. DeMarr’s death in 1997. The library houses approximately 6,000 volumes on subjects ranging from architecture to educational institutions to military history and transportation; it also houses an outstanding collection of historical maps, archival photos, journals, and newspapers, as well as extensive files on places, events, and individuals. Complete sets of the Archives of Maryland and the Maryland Historical Magazine are available at the library, which also offers on-line services, and assistance in all types of research.
The library is operated by an all-volunteer staff, including professional research instructors. Use of the collection is offered to the public free of charge, with nominal fees for copies. The library is located on the lower level of the Greenbelt Library building at 11 Crescent Road in Greenbelt.
