AMA Citation Style

AMA Citation Style
AMA (American Medical Association) is the standard referencing style used by researchers, editors, and students in the medical, health, and science field. The system was developed by the editors of JAMA (Journal of American Medical Association) to provide authors and editors with a clean and clear style for uniformity in style, format, and structure of the documents. Extensive and regular updates are also provided regarding the citation of different source materials such as books, journals, articles, digital publications, among others.
In-text citation using AMA reference style
The AMA style uses superscripted numbers in a chronological order to cite sources within the body of a document. Only these superscript numbers will appear in the text, while full and more detailed references corresponding to the numbers are provided in the bibliography at the end of the manuscript. The numbers should be placed at the end of the relevant sentence after periods or commas and inside of colons and semicolons. Unlike other styles, In-text citation in AMA does not include the name of the author, title of the article, year of publication, or the page numbers.
In-text example:
The sky is blue.1
The Bibliography
The bibliography is given at the end of the document on a separate page. It lists all the sources used in the text, as presented by the superscript numbers. Therefore, the entries containing the full references must always be given, starting with the citation numbers and following the sequence of the superscript numbers as they appear within the text. The format employed when making the entries in the reference list also varies depending on the source.
When citing books, you can include up to a maximum of six authors. For more than six authors, only the first three authors are listed, followed by “et al.”. If the author is not given, use the title of the source. The format when citing a book should contain, name of the author(s) of the chapter, main author of the sourcebook, page number/range, edition, name of the publisher, location of publishing, and year of publishing.
Example when using one author
1. Frumkin H, ed. Environmental Health: From Global to Local. San Francisco, CA: Jossey-Bass; 2005.
Example when using more than six authors:
16. Brown JE, Smyth PT, Xu Y-C, et al. AMA reference style. J Med Style. 2007;26(1, pt. 2):98-103.
For journal articles, newspapers, and magazines, only abbreviated titles are used. The format should contain author names(s), the title of the publication, year of publication, volume and issue, and the page number/range.
Example:
Cropley TG. Dermatology and skin disease in the American Civil War. Dermatol Nurs. 2008;20(1):29-33.
