Primary and Secondary Sources

Published Documents

When reviewing published documents, remember that just because something was published does not make it truthful, accurate, or reliable. Every document has a creator, and every creator has a point of view, blind spots, and biases. Also remember that even biased and opinionated sources can tell us important things about the past.

Unpublished Documents

Many types of unpublished documents have been saved, and can be used as primary sources. These include personal letters, diaries, journals, wills, deeds, family Bibles containing family histories, school report cards, and many other sources. Unpublished business records such as correspondence, financial ledgers, information about customers, board meeting minutes, and research and development files also give clues about the past.

Unpublished documents often come from community organizations, churches, service clubs, political parties, and labor unions in the form of membership lists, meeting minutes, speeches, financial and other records. Government at all levels creates a variety of unpublished records. These include police and court records, census records, tax and voter lists, departmental reports, and classified documents.

Visual Documents and Artifacts

Visual documents include photographs, films, paintings, and other types of artwork. Because visual documents capture moments in time, they can provide evidence of changes over time. Visual documents include evidence about a culture at specific moments in history: its customs, preferences, styles, special occasions, work, and play.

Like other primary source documents, a visual document has a creator with a point of view -- such as a painter, sculptor, or film maker. Even photographs were created by photographers using film and cameras to create desired effects.

Oral Traditions/Oral Histories

Oral traditions and oral histories provide another way to learn about the past from people with firsthand knowledge of historical events. Recently, spoken words that make up oral histories have gained importance as primary sources. Historians and others find out about the lives of ordinary people through spoken stories and tales. Oral histories provide important historical evidence about people, especially minority groups, who were excluded from mainstream publications or did not leave behind written primary sources.

Oral histories are as old as human beings. Before the invention of writing, information passed from generation to generation through the spoken word. Many people around the world continue to use oral traditions to pass along knowledge and wisdom. Interviews and recordings of community elders and witnesses to historical events provide exciting stories, anecdotes, and other information about the past.
