A primary source is a piece of evidence created during the time you are studying. These sources offer an eye-witness view of a particular event. They can be any type of format, as long as you as the researcher are looking for the source's context: Who made this, and what was their perspective? What other sources describe the same events? Whose perspective isn't represented, and where can you find it? What was the world like when this thing was made? With primary sources, you will ask a lot of questions!
Some common types of records used as primary sources include:
Remember: you have to find context for your primary sources.
A secondary source interprets and analyzes primary sources. Secondary sources may have pictures, quotes or graphics of primary sources in them. Some common types of secondary sources include:
Remember: a secondary source is making an argument based on research from other primary and secondary sources.
In the Humanities (history, literature, religion), primary sources focus on original documents or accounts contemporary to a specific event or an individual’s life. Terms such as “eyewitness” or “firsthand” are also commonly used to describe these sources. Autobiographical accounts written at a later date are also considered primary sources. Letters, diaries, journal entries, public records as well as contemporaneous newspapers articles offer solid examples of this type of primary source. Fictional works such as short stories or novels written during that specific time period constitute primary documents, too.
In the Arts (art, dance, music, theatre), primary sources are as diverse as the various disciplines in the category. They may include paintings, sculpture, prints, performances, video or audio recordings, scripts, or musical scores.
Social Sciences (psychology, sociology, education) place a heavy emphasis on unanalyzed data sets as primary sources. Numerical data sets such as census figures, opinion polls, surveys or interview transcripts constitute this type of raw, uninterpreted data. A researcher’s field notes are also primary sources in the social sciences.
In the Sciences (biology, ecology, chemistry), primary source documents focus on original research, ideas, or findings published in academic journals. These articles mark the first publication of such research; and they detail the researcher’s methodology and results. Plant or mineral samples and other artifacts are primary sources as well.
In STEM fields, primary sources may include papers or proceedings from scientific conferences; journal articles sharing original research, technical reports, patents, lab notes, and researcher correspondence or diaries.
