SCA Frequently Asked Questions


Do you have a question about the Society for Commercial Archeology (SCA)? If it is not answered here, please look here for more contact options.

Where is the archeology in SCA?

The SCA focuses on a field of archeology that is often referred to as above ground archeology (the term was coined by John L. Cotter of the National Park Service and refined by Thomas Schlereth of Notre Dame). Research takes place above ground level and includes the study of buildings and the landscape. But piecing together these above-ground elements, it is possible to interpret the past and its importance to contemporary matters. Schlereth considers the following in his definition of above-ground archeology:

Geological/Geographical Features

Landscape Vegetation

Place and Street Names

Street Histories

Vernacular Buildings

Working Places

Commercial Archeology

What is commercial archeology?

In the Dictionary of Building Preservation (1996), commercial archaeology is defined as “The study of artifacts, structures, signs, and symbols of the American commercial process; includes both mass-produced and vernacular forms of the machine age: transportation facilities, such as highways and bus stations; roadside development, such as diners, strip retail, and neon signs; business district buildings, such as movie theaters and department stores; and recreation facilities, such as amusement parks.”

What is roadside architecture?

The term roadside architecture applies to buildings and other structures directly and indirectly associated with roads. Obvious examples include restaurants, motels, and gas stations. Other examples include signs, vernacular buildings, shopping and retail centers, and programmatic (or mimetic) structures, as well as theme and amusement parks.

What is the SCA's mission?

The mission of the SCA is to recognize the unique historical significance of the 20th-century commercial built environment and cultural landscapes of North America, emphasizing the impact of the automobile and the commercial process. To this end, the SCA will carry out projects of documentation, education, advocacy, and conservation to encourage public awareness and understanding of these significant elements of our heritage.

How did the SCA begin?

The SCA was organized by a group of scholars and experts who had an interest in commercial archeology. The group met in Vermont, and in 1979 they formally organized.

Where is the SCA located?

At present, the operations of the SCA are managed throughout the country by the members of the board of directors.

Does the SCA have an archive?

How do I save an important roadside building or structure?

Start by contacting your state historic preservation office, statewide preservation non-profit organization, or local preservation organizations in your area (click here for a directory of preservation organizations). Make sure to share details about the resource, including the nature of the threat and photographs. Additionally, contact organizations that are directly interested in the type of resource, for example, the United Drive-In Theatre Owner’s Association.

If the resource is endangered, consider a nomination to our Falling by the Wayside program, the SCA’s official list of endangered roadside places. You may also contact your state or local preservation organization, who might also retain a list of endangered places.

Lastly, don’t give up! Preservation efforts can take years and many hours of dedication. Find local allies who believe in your cause. The National Trust for Historic Preservation includes Preservation Tips and Tricks for saving historic resources.

What is the SCA interested in?
