The Frederick S. DeMarr Library of County History was founded by Fred DeMarr, who was President and Historian of the Society for a number of years. Mr. DeMarr was a life-long resident of the County and had an abiding interest in all aspects of County History. His collection was donated to the Society by the DeMarr family after his untimely death in 1997.

The library has moved to the Greenbelt Public Library building, 11 Crescent Road in Greenbelt (301-220-0330). The public is invited to the opening ceremonies at 1:00 p.m., Saturday, May 31, 2008. After the official opening, we will resume the regular library hours of noon to 4:00 p.m. on Saturdays and by appointment.

The Library is staffed by a dedicated team of volunteers including Susan Pearl, Historian, Sarah Bourne, Dusty Rhoads, and Diane Stultz, Genealogical Research Specialist. Specific questions concerning aspects of the history of Prince George's County may be directed by telephone to 301-464-0590, on the web message board, or by email to the Society at info [at] pghistory.org.

The Society is currently engaged in cataloging the collections of written materials, maps and ephemera, and has a partial listing here. Materials do not circulate but may be used at the Library. Copies of non-copyrighted materials may be secured for a modest copying fee. Request for copies of materials should be directed to the Society at info [at] pghistory.org.
