Secondary vs Primary





***Note: there is often a grey area between these categories, so exercise your judgment and critical thinking in evaluating your information sources.

Secondary Sources

  • Secondary sources are books or articles written about a topic using primary sources.
  • Secondary sources interpret original documents that give you background information about the topic you want to research.
  • Examples of secondary sources are: articles, dictionaries, encyclopedias, textbooks and books that interpret or review research works.

Primary Sources

  • A primary source is first hand evidence. It was there at the time of an event. It is contemporary to the period being studied.
  • Examples of primary sources are: speeches, letters, comics/cartoons, songs, legislation, court decisions, journals/diaries, interviews, artifacts, autobiographies, statistics, experiments, and photographs.

Here's a real life example of primary and secondary sources:


Suppose there had been an accident. The description of the which a witness gives to the police is a PRIMARY SOURCE because it comes from someone actually there at the time. The story in the newspaper the next day is a SECONDARY SOURCE because the reporter who wrote the story did not actually witness it. the reporter is presenting a way of understanding the accident or giving an interpretation.
