Primary Source vs. Secondary Source

Primary sources are documents (or other kinds of materials) that were created in the past that can be used by researchers in the present to gain insight into a specific time period. Primary sources provide ideas and evidence about events in the past. Scholars use the evidence found in primary sources to draw conclusions and construct narratives about the past.

Types of primary sources: Diaries, speeches, manuscripts, photographs, letters, oral history interviews, news film footage, autobiographies, official records, meeting minutes, and can include objects such as pottery, furniture, clothing, and buildings.

Primary source documents exist as such only after the passing of time; they were not necessarily created to support historical analyses. They are typically the day-to-day documents that support the functioning of a business or organization or an individual. Over time, these documents remain and can lend insight into specific time periods, organizations' and individuals' histories. But it is important to note that this is their secondary, not original function.

Secondary sources are published works that present arguments and conclusions about events in the past based on primary source (or archival) research. Types of secondary sources include: textbooks, magazine articles, histories, criticisms, commentaries, and encyclopedias.

  • What kinds of factual information does it provide?
  • What is conveyed, but not necessarily intentionally?
  • What is not conveyed in this source? What isn't being said?
  • What us surprising, unique, puzzling, interesting in this source?
  • How does the creator of this source convey information?
  • How is the world today different than when this document was created?
  • How might this source have been received in its time?
