Hi Linda,
It depends on the system you're using (e.g., APA, MLA, Chicago).
For APA, check out this site: https://apastyle.apa.org/learn/faqs/references-in-parentheses
For MLA, look at this sample MLA paper that follows the 8th edition: https://style.mla.org/app/uploads/sites/3/2017/03/Samantha-Paper_FINAL.pdf
For Chicago Turabian, look at a sample reference list published by the Chicago Manual of Style: https://www.chicagomanualofstyle.org/dam/jcr:a9c0aa5d-0e45-4b6e-9db4-2a336208f5fa/Turabian-Tip-Sheet-14.pdf
Please reach out to me if may provide more specific assistance. I'm happy to help!
Keri
