Secondary Sources

What are Secondary Sources?

Secondary Sources use primary sources to answer research questions, solve problems, and interpret the past.  The authors or creators of these sources were not present at the time of the event they seek to explain.

There are incidents when secondary sources may become primary sources. For example, if you were researching trends among scholars’ interpretations of an event, you would want to turn to the secondary publications of those scholars to support your thesis. These publications become your primary sources.

   Examples of secondary sources:

  • textbooks
  • encyclopedias
  • magazine articles
  • reviews and commentaries
  • books about past events for which the author was not present
