The Oregon Century Farm and Ranch Program Records document farms and ranches in Oregon that have applied for and received recognition as Century or Sesquicentennial Farms or Ranches. The records consist primarily of application materials; a database listing all the farms and ranches accepted into the program is also included. The Oregon Century Farm and Ranch Program was established in 1958. The records are closed for research at this time for processing and digitization, but data can be accessed on the Century Farm and Ranch Public Data Export page.
The Sanborn Fire Insurance Maps of Oregon are an extensive collection of detailed maps of 178 towns and cities in Oregon beginning in the 1880s. The maps depict both business and residential areas and provide information about the location of structures and type of construction. These can be used to locate breweries and other structures like ice houses, but researchers need the name or rough location of the brewery to determine the exact location.
The Metsker's Atlases of Oregon Counties consist of 66 atlases and include one or more atlases for all 36 Oregon counties that depict property owners and donation land claims. The bulk of the atlases were published in the 1930s-1950s. Each atlas includes an index map. In addition to property boundaries, the maps show roads; railroads; streams, rivers, and water bodies; and schools. Most of the atlases were compiled by Charles F. Metsker, a civil engineer; the more recent atlases were prepared by Thomas C. Metsker. These can be used to locate hops farms, but researchers need the name of the farm owner to identify the location.
