AMA Style is a variation of the Vancouver system that is used by the Journal of the American Medical Association (JAMA) and other publications by the AMA. We are currently following the 11th edition of the AMA style guide.
AMA is a documentary-note style, which means you put a number in your text to cite sources of information and the reference list is in numerical order.
In text citations are in superscript1 and in order of citation (the first citation is 1 the next is 2). If you use the same source again, you keep the same number (the source you used for the first citation is always 1, even if you use it again after 6).
See the page on In-Text Numbering in the full style guide for more detail.
General Notes:
Chapter 3 of the AMA Manual of Style 11th ed.
The information in this guide has been taken primarily from the referencing chapter of the AMA Manual of Style 11th ed. You can download PDFs of the chapter here.
The AMA Style Insider is the official AMA Style blog. It can provide answers to some of your questions, particularly if you are trying to cite something unusual.
The following guidelines are based on the minimum requirements for AMA citations. AMA style requires this core information for each citation (additional details can be added where appropriate – see the relevant pages in the full UTSW AMA guide using the links on the left).
Pay close attention to punctuation use in the examples – including case, italics, the order of dates and spaces.
A DOI is preferable to a URL if one is available. No accessed date is required for the DOI because it is a permanent identifier.
You must include an accessed date for URls as they are subject to change.
