Use in-text citations to tell the reader where you got any information that did not come from inside your own head. This is more obvious when you are directly quoting from a source, but it is also needed when you have summarized or paraphrased from a source, or even when you use an idea from a source.
So how do you do it?
With AMA style, you will use superscript arabic numerals to number each of the sources in your text, tables, or figures. The sources are numbered consecutively and refer to the sources listed on the "References" page at the end of your paper.
In-Text Citation Examples:
