The Agricultural and Resource Economics Department Photographs consist of images taken by Oregon State College County Agents, Farm Management Department faculty and staff, and Agricultural Economics Department faculty. The photographs depict agriculture in Oregon, including livestock, equipment, and crop fields. Additional images document damage caused by the 1945/1946 Willamette River flood, pasture scenes, operations of the Duckwall Fruit Processing Plant, and fruit harvesting and processing in Wenatchee Valley, Washington.
The Washington County (Or.) Extension Service Records document educational and outreach programs offered by the Oregon State University Extension Service in agriculture, home economics, and 4-H. The bulk of the records consist of annual reports. Washington County received its first County Extension Agent in 1917.
