Use OneSearch or our Databases to find credible sources. To check they are credible, ask yourself two questions: 

1. Who is writing? 

  • They should be an expert who has at least a master's degree in the subject. 
  • For primary sources, this will be a person who has significant personal experience (e.g., a Holocaust survivor talking about their experience of the Holocaust). 

You can google their name to find this information.

2. On what topic? 

  • It should be a subject the expert studied (e.g., a nurse writes about a medical topic). 
  • Primary sources should talk only about his/her experience (e.g., a police officer talking about their experience working with homeless people). 

Take a look at our Evaluating Sources tutorial for more examples. You can also schedule a research appointment and a librarian will help you find credible sources for your research.
