 In-Text Citation Examples

AMA Style uses superscript numbers for in-text citations. The superscript comes after quotations, periods, and commas. The superscript goes immediate following the information including mid-sentence.  At the end of the paper list References with their number in the order they appear in the paper. 

Examples of in-text citations:

If the sources are not consecutive use commas.

Digital Object Identifier (DOI)

What is a DOI, and how do I find it? A DOI is an alpha-numeric code that provides a persistent link to an article location on the Internet. With an HTML full-text article, the DOI is often found in the online citation of the article. With a PDF article, the DOI is often found on the beginning page of the article. Not all articles have a DOI.
