Reference lists are in numerical order, based on the order in which the sources were first cited in your assignment.
The AMA style guide does not give specific instructions for the layout of the reference list, but the following advice is based on the formatting of reference lists in both the style guide and the journals published by the JAMA family.
Do not begin the reference list on a new page, but place it at the end of your document, after a space or a line. It follows any article information or acknowledgments. Put the word "References" in all caps, and in line with the left-hand margin. Format the numbers as per normal numbering style within Word (or similar programmes).
