For instance, if a scientific study is performed, the primary source is the initial report that is prepared by the scientist(s) who performed the research. Secondary Source: A secondary source is a document that is written about the primary source
Historians use primary sources as the raw evidence to analyze and interpret the past. They publish secondary sources - often scholarly articles or books - that explain their interpretation. When you write a historical research paper, you are creating a secondary source based on your own analysis of primary source material. Examples of primary sources include diaries, journals, speeches, interviews, letters, memos, photographs, videos, public opinion polls, and government records, among many other things.
