Whenever you quote or paraphrase source materials in your paper, you will need to cite where the original information came from. The AMA style uses numbers as superscripts that refer to full citations in the reference list. These numbers are given in chronological order from where they are referenced in the paper. Use the same number when you refer to that source again, include page numbers if necessary.
Use numbers as a superscript outside periods and commas.
Multiple sources can be cited together. If the sources are consecutive, separate them with a hyphen. If they are not, use commas without a space to separate the numbers.
Direct quotes should include page numbers.
Using numerical citations instead of a name-year system can be frustrating as you edit your paper. You may need to add, move, or remove a citation, which will change the order of your reference list and the numbers for each new citation after the change. Manually changing each of these numbers with every revision is stressful and time consuming, and it has very little effect on the content of the paper. The following is advice from someone with experience using numerical citations and is not part of any official citation style.
