Some basic techniques and resources required for researching a historic property. Whether the research is intended for personal or academic interest, or for the nomination of a property to the National Register of Historic Places,the following information will help the researcher get started.

1. Asking the Right Questions:

Research for a National Register nomination must demonstrate the property’s historic significance, defined as the importance of the property to the history, architecture, archeology, engineering or culture of a community, a State or the nation. Significance is based on four criterion: association with historical events; association with a significant person; distinctive physical characteristics of design, construction or form; and the potential to yield important information.

A nomination must also place the property in its historic context, establishing the property’s direct connection with the designated area of significance; clearly set the boundaries of the property’s period of significance; and demonstrate the property’s integrity, defined as the authenticity of the property’s physical characteristics. To evaluate the property’s significance, the researcher must answer the following questions:

  • How large is the property, where is it located, or what are its boundaries?
  • How many buildings, structures, and other resources make up the property?
  • When was the property constructed? By whom was the property designed and/or constructed?
  • Does the property have a historic name or names? What is the source of those names?
  • What are the property’s historic characteristics?
  • What changes have been made since its initial construction and when?
  • How have these changes affected the historic integrity?
  • What was the historic function/use of the property? How is it used today?
  • What is the current physical condition of the property, including the exterior, grounds, setting and interior?
  • Who occupied/used the property historically? Who is the current owner?
  • Was the property associated with any important events, activities, or persons?
  • In what areas of history is the property significant?
  • How does the property relate to the history of the community in which it is located, of the State, and/or of the nation?

2. Preliminary Resources:
With a list of questions prepared, the researcher may then begin to identify the primary and secondary resources needed to answer those questions. Some initial hints include:

  • Begin with the most crucial primary source: the property itself.
    Compile a detailed description of the physical characteristics of the property’s grounds and setting, including the exteriors and interiors of all buildings, structures on the site. Note any distinctive features, obvious alterations or changes, and any signs of previous buildings or activities, (foundations, wells, paths, vegetation, roads, etc.).
  • As early as possible, establish the property’s date of construction, if only initially a rough time frame (for example, 1835-1850). Also, discover the names of any persons or institutions associated with the property and any alternate names by which the property has been known. This information will immediately provide a focus to the field of inquiry, facilitating the research tasks.
  • If possible, talk with current and/or past owners, neighbors, and long-time residents of the community. In addition to the physical records (deeds, abstracts, building permits, receipts etc.), personal recollections can contribute greatly to your understanding of the social and cultural significance of the property and lead to new sources of information.

3. Locating Primary & Secondary Sources:
Researching a property entails the careful examination of both primary (archival & original) and secondary sources of information. The following list identifies potentially useful types of materials:
