Examples in the humanities:

  • a novel
  • a painting
  • a theatre performance

Examples in the social sciences:

  • a political, social, or economic theory
  • a dataset
  • the results of an experiment published in a peer-reviewed journal

Primary Sources in the Sciences

Primary sources in the natural sciences are publications which provide a full description of original research and the presents the results of that research. The most common example of a primary source in the sciences is a scholarly article published in a peer-reviewed journal. Primary sources in the sciences include a description of the research and the results and references to other research in the field, and are factual, not interpretive. They can also take the form of more personal records and correspondence, including lab notebooks, diaries, and letters.
