Notes for books and book chapters:

  • Do not include the publisher location.
  • If the print book or eBook has a DOI, include the DOI in the reference after the publisher name.
  • Do not create references for chapters of authored books. Instead, write a reference for the whole book and cite the chapter in the text if desired (e.g., Kumar, 2017, Chapter 2).

Journal article

Notes for journal articles:

  • Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate.
  • If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a subscription database), include the URL of the article at the end of the reference.
  • If the journal article has an article number (ie. Article e0193972) instead of a page range, include the article number instead of the page range.
  • Up to and including twenty authors should be listed in the entry in the reference list.

Notes for magazines and newspaper articles

  • If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a webpage on a website instead.

Webpage from website, if content does not change over time.

Author, A. A. (year of publication, Month date). Webpage title. Website Title. https://url

National Institute of Mental Health. (2018, July). Anxiety disorders. U.S. Department of Health and Human Services, National Institutes of Health. https://www.nimh.nih.gov/health/topics/anxiety-disorders/index.shtml

Webpage from website, if content changes over time.

Author, A. A. (year of publication, Month date). Webpage title. Website Title. Retrieved Month date, Year from https://url

Fagan, J. (2019, March 25). Nursing clinical brain. OER Commons. Retrieved November 26, 2019 from https://www.oercommons.org/authoring/53029-nursing-clinical-brain/view

Notes for websites:

  • Provide as specific a date as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
  • When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition.
  • If the author is missing, the title moves to the beginning of the reference and is used in place of the author name.
  • Generally, a retrieval date is not required. Only include a retrieval date in the reference if the information is designed to change over time (e.g., Wikipedia). Only use “Retrieved from” when you are including a retrieval date. Including the date indicates to readers that that they are likely to access a different version of the webpage.
  • Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers).
  • Use the newspaper article category for articles from newspaper websites such as The New York Times or The Washington Post.
  • Do not create a reference or in-text citation for a whole website.
