You will probably want to check with your instructor first, because they may have specific requirements.

Otherwise, if this is research paper, it depends on the citation style you are using. Here are links to the Online Writing Lab at Purdue:

APA: https://owl.english.purdue.edu/owl/resource/560/01/

Hope that helps.
