As this University of Georgia Libraries video states, "primary sources are documents, artifacts, or other materials created by people directly connected to your topic. A primary source might be connected in this way to:
Examples of primary sources include: photos, maps, diaries, art, letters, newspaper articles, laws, speeches, audio recordings, autobiographies, oral histories, government records, advertisements, statistics, and material artifacts.
Primary sources, therefore, are original documents and contemporary accounts of an event or phenomenon (UC Santa Cruz Library).
