What is a primary source?

A primary source is a direct or firsthand piece of evidence related to a particular event, topic, or time period. This can include original documents such as letters, photographs, official records, diaries, speeches, or any material that has not been altered or interpreted by someone else. Primary sources provide insight and evidence from the perspective of those who experienced or witnessed the events themselves, making them invaluable for research and understanding historical contexts.

In contrast, the other choices do not fit the definition of a primary source. A secondary analysis involves interpreting and discussing primary sources or events, thus making it secondary. An interpretive essay presents an analysis or viewpoint rather than original evidence, while a summary of existing documents consolidates information from various sources, rather than presenting firsthand accounts or artifacts.
