Frequently Asked Questions

What is AMA citation format?

AMA (American Medical Association) format is a citation style used primarily in medical, health sciences, and biomedical research. It uses superscript numbers in the text and a numbered reference list at the end of the paper, ordered by first appearance. The current version is the AMA Manual of Style, 11th edition (2020).

How do I cite a journal article in AMA format?

For journal articles in AMA format, list authors (last name followed by initials without periods), the article title, abbreviated journal name in italics, year, volume, issue in parentheses, pages, and DOI. Example: Smith AA, Johnson BB. Machine learning in diagnostics. Nat Med. 2024;29(4):123-145. doi:10.1038/s41591-024-00001

What is the current AMA edition?

The current edition is the AMA Manual of Style, 11th edition, published in 2020. It is the standard reference guide for medical and scientific publishing, covering citation formatting, grammar, nomenclature, and ethics.

How do AMA in-text citations work?

AMA uses superscript Arabic numerals (1, 2, 3) placed after punctuation in the text. Sources are numbered in the order they first appear. If the same source is cited again, it keeps its original number. Example: "Recent studies have shown improvement in outcomes.¹"

Is this AMA citation generator free?

Yes. CiteMe lets you generate AMA 11th edition citations for free. Search real academic databases including PubMed, OpenAlex, and Semantic Scholar to find and format medical references automatically.

What is the difference between AMA and APA?

AMA uses superscript numbers for in-text citations and a numbered reference list (ordered by first citation), while APA uses author-date in-text citations (Smith, 2024) and an alphabetical reference list. AMA is standard in medicine and health sciences; APA is used in psychology and social sciences.

How do I cite a website in AMA format?

For websites, include the author (if available), title of the page, website name, publication date, accessed date, and URL. Example: Smith AA. Mental health guidelines. World Health Organization. Published January 10, 2024. Accessed March 1, 2026. https://www.who.int/mental-health

When should I use AMA citation style?

Use AMA style when writing for medical journals (such as JAMA, Archives of Internal Medicine), health sciences courses, nursing programs, or any biomedical research publication. Many medical schools and health-related academic programs require AMA formatting.

How do I list multiple authors in AMA format?

List up to 6 authors by last name and initials (e.g., Smith AA, Johnson BB, Williams CC). If there are 7 or more authors, list the first 3 followed by "et al." Do not use "and" between author names.

How is the AMA reference list ordered?

Unlike APA or MLA, the AMA reference list is numbered and ordered by first appearance in the text — not alphabetically. Each source receives a unique number when first cited, and that number is reused for subsequent citations of the same source.
