Welding Technology: Primary v. Secondary Sources

This guide supports the research needs of students enrolled in Welding Technology diploma, certificate, and CCP programs at Brunswick Community College.

What is the difference between primary and secondary sources?

You ask: 

My instructor says I have to use at least one (1) primary source in my paper and at least two (2) secondary sources.  What is the difference between primary and secondary sources?

We answer: 

  • A primary source is a document or physical object written or created during a time period of study and provides an insider or first-hand view of an era, event, person, object, and/or idea, including original scientific research and/or data.
  • Secondary sources are documents that comment on or analyze and synthesize primary sources and/or original scientific research and/or data.
