10ABOUT
What is BARC?
Since 1910 the Beltsville Agricultural Research Center has occupied a vast federal landscape just outside Washington, D.C. — thousands of acres where crops, animals, soils, insects, food, buildings, and fields all became subjects of research for the United States Department of Agriculture.
That century of work left an equally sprawling record: annual reports, field photographs, seed catalogues, maps, and bulletins, now scattered across public collections. This project brings those traces back together — in public, as the record accrues — so the history and the work of reconstructing it are both in view.
