Primary and Secondary Sources

A primary source is an original document. Primary sources can come in many different forms. In an English paper, a primary source might be the poem, play, or novel you are studying. In a history paper, it may be a historical document such as a letter, a journal, a map, the transcription of a news broadcast, or the original results of a study conducted during the time period under review. If you conduct your own field research, such as surveys, interviews, or experiments, your results would also be considered a primary source. Primary sources are valuable because they provide the researcher with the information closest to the time period or topic at hand. They also allow the writer to conduct an original analysis of the source and to draw new conclusions.

Secondary sources, by contrast, are books and articles that analyze primary sources. They are valuable because they provide other scholars’ perspectives on primary sources. You can also analyze them to see if you agree with their conclusions or not.

Most essays will use a combination of primary and secondary sources.
