What is a secondary source?

Secondary sources analyze, describe, discuss, or summarize primary sources. In general, a secondary source is one or more steps removed from the event, time period, or person being discussed, and are written after the fact with the benefit of hindsight. Secondary sources can include:

  • Biographies
  • Reference sources like dictionaries or encyclopedias
  • Literature reviews
  • Works of criticism or interpretation as in many scholarly articles

Search Techniques

1.  Once you know your research interest, formulate it into a question and use the most important parts to generate keywords. Here, "Star Wars" and "myth" are the key parts of the topic, so those will be the keywords. 

2. You can then use Boolean operators (AND, OR, NOT) to better refine your search.
