AMA 11th Edition Citation Guide: Everything You Need to Know
Mastering the AMA citation format is a rite of passage for every medical student and researcher. As of 2026, the AMA Manual of Style (11th Edition) remains the definitive standard for health sciences.
Unlike APA or MLA, the AMA style uses a numerical system that keeps your medical papers clean and focused on the data. In this guide, we break down the most critical rules for AMA style citation, from superscript numbers to the "et al" rule, to help you build a flawless reference list.
The Anatomy of an AMA In-Text Citation
The most recognizable feature of ama in-text citation is the use of Arabic superscript numerals (1, 2, 3).
Key Placement Rules:
- Sequence: Numbers are assigned in the order they appear in the text. If you cite a source again, use its original number.
- Punctuation: Place superscript numbers outside periods and commas (e.g., ...as seen in previous trials.1), but inside colons and semicolons.
- Multiple Sources: If citing more than one source at once, use commas without spaces for non-consecutive numbers (2,5,8) and hyphens for a range (1-3).
The "Et Al" Rule: How Many Authors?
One of the most frequent searches for an ama 11th edition citation generator is how to handle multiple authors. The 11th Edition rule is very specific:
- 1 to 6 Authors: List all authors' names in the reference list.
- 7 or More Authors: List the first three authors, followed by "et al."
- Format: Smith JA, Doe JB, Williams RT, et al.
Note: In AMA style, there is no period after the "et al" unless it’s at the end of a sentence!
Citing Journal Articles (The Gold Standard)
Most of your ama format citation work will involve journals. The 11th Edition has simplified this by removing the publisher's location.
The Formula
Author(s). Title of article. Abbreviated Journal Title. Year;Volume(Issue):Pages. doi:10.xxxx/xxxx
Example:
Mark S, Utility M. The rise of digital medical utilities in 2026. J Med Tech. 2026;15(2):104-110. doi:10.1017/S1460396

Free AMA Citation GeneratorFrequently Asked Questions
Do I need to include an access date for websites?
Yes. For any source with a URL, AMA 11th Edition requires the "Accessed [Date]" format after the publication date.
Is the reference list alphabetized?
No. Unlike APA, an ama style citation list is numerical, following the order of appearance in your paper.
What is sentence case?
For article and book titles, only the first word and proper nouns are capitalized. Journal titles, however, use Title Case (capitalizing all major words).
