Local History in the Special Collections and Archives Research Center

Additional Resources

A number of agencies, organizations, and resources external to the Special Collections and Archives Research Center (SCARC) are available to assist you in your local history research. Just a few of these resources have been listed below, arranged at the city, county, state, and national level. Contact information, where available or applicable, has also been provided for each of the agencies or organizations.


Some of the cities in Benton County, including those listed below have their own historical societies. Additional local institutions that may serve as useful resources include:

City libraries can also be useful resources for genealogical and/or local history research. For example, both the Corvallis-Benton County Public Library (CBCPL) and the Valley Library at OSU have a complete run of the Corvallis Gazette-Times on microfilm. The Valley Library and CBCPL also have physical copies of Polk City Directories, a useful tool in any local historian's arsenal, as they include additional personal details about the residents listed, often including marital status, occupation, and the names of family members. The CBCPL holds Polk City directories for Benton County and the city of Corvallis. The Valley Library and SCARC hold a variety of Polk City directories for Linn and Benton County, and the cities of Corvallis, Salem, and Portland (check specific catalog listings for years).


Many counties across Oregon have their own historical societies, and all counties have both a Clerk's and Surveyor's Office. The Oregon Blue Book County Government page includes an interactive map which links out to contact pages for each county's governmental departments.

  • Benton County Historical Society: The collections of the Benton County Historical Society are comprised of over 120,000 artifacts including photographs, historical documents, textiles, clothing, domestic arts, farm implements, scientific instruments and personal possessions. You can access their online collections database here: Benton County Historical Society Collections Database.
  • Benton County Clerk's Office: A great resource for vital records such as birth, marriage, and death.
  • Benton County Surveyor's Office: Can provide information on property line surveys, property line adjustment surveys, partition and subdivision plats, and oversees the county road list. Surveyor's offices often have access to additional resources as well, such as aerial photographs and Metsker atlases.
