What Are Primary Sources?

Primary sources are “first hand”accounts of an event, an occurrence, or a time period produced by a participant or observer at the time, or shortly thereafter. They can be published or unpublished.

Typically, primary sources include:

Unique documents or manuscripts - letters, diaries, journals, writings, speeches, photographs, scrapbooks, etc.

Historic records of an organization - correspondence, memoranda, minutes, annual reports, etc.

Government documents - records, maps, and statistical data

Artwork and artifacts

Music and audiovisual materials - film, audio and video tape

Speeches and oral histories - printed transcripts or audio recordings

Photographs and advertisements

Electronic computer files - including emails

This tutorial from University of Guelph Library explains what primary sources are, and how they differ from secondary sources.

How Do I Distinguish Between a Primary Source, a Secondary Source and a Tertiary Source?

Primary sources are the surviving original records of a period, eyewitness accounts and first-published documentation of new information.

Examples of primary sources include:

Peer-reviewed journal articles about one's original research or ideas.
Autobiographies, letters, diaries, and journals describing one's personal experience, activities, and the people, places and events at the time.
Oral histories, interviews and ethnographic research records.
Sound and video recordings of an event or people.
Published material written at the time, such as newspapers, books and articles.
Government or court records including birth and death certificates, deeds, trial transcripts, census records, patents, treaties and other documents.
Business records such as reports, surveys and minutes of meetings and conferences that document contemporaneous activities, people and events.
Art such as architecture, sculpture, photographs, drawings, maps, posters and cartoons.
Written creations such as literary works, sacred texts and musical scores.
Artifacts such as tools, weapons, crafts, furniture, buildings, roads, machines or other objects made by humans living at the time.

Secondary sources interpret the past and analyze primary sources.

Examples of secondary sources include:

Journal articles that review the original work of others.
Biographies and histories written by people who did not experience events or the time first-hand.
Commentaries and criticism of primary sources.
Historical studies, literature reviews and textbooks.
Magazine articles and Web pages which describe events or ideas a substantial time after they have occurred.

What Questions Should I Ask?

In the Arts:

1. Was the source created during the time period you're studying? If the answer is yes, you are looking at a primary source.

2. Is it an object from a particular time in history? (Archie Bunker's chair? An Emily Dickinson poem?) This also counts as a primary source.

3. Was the source written after an event took place? If so, it is a secondary source.

In the Sciences:

1. Is the source reporting original research?

2. Did the author(s) carry out this original research?

If the answer to the two above questions is yes, it is a primary source.
