What Is AMA In Text Citation? π
AMA in text citation is the citation method used in the American Medical Association (AMA) citation style. Instead of using the author’s name and publication year inside the text, AMA assigns each source a unique number.
The first source you cite becomes 1, the second becomes 2, and so on. Every time you use the same source again, you reuse its original number instead of assigning a new one.
This numbering system keeps academic writing clean, organized, and easy to read.
Quick Overview of AMA Citation Style π
| Feature | Details |
|---|---|
| Citation Method | Numbered references |
| In-Text Format | Superscript or regular Arabic numbers |
| Reference Order | Listed in the order sources first appear |
| Reuse of Sources | Use the same citation number every time |
| Common Fields | Medicine, Nursing, Pharmacy, Public Health |

How to Create an AMA Reference List π
Every AMA in text citation must match a complete entry in the reference list. Unlike some citation styles that arrange references alphabetically, AMA organizes references in the order they first appear in your document.
For example, if a journal article is the first source mentioned in your paper, it will be listed as reference number 1. If a book is the second source you cite, it becomes reference number 2.
This numbering remains the same throughout your document, even if you cite the same source multiple times.
| Reference Number | Source Type |
|---|---|
| 1 | Journal Article |
| 2 | Book |
| 3 | Website |
| 4 | Government Report |

Although every source follows specific formatting rules, the general structure remains consistent. Here are simplified examples to help you understand how different references are organized.
Journal Article Example

Book Example

Website Example

Common Mistakes When Using AMA In Text Citation β

Changing Citation Numbers

Using Different Formats Together
Avoid mixing AMA with APA, MLA, or Chicago formatting within the same document.
Incorrect Reference Matching
Each citation number must match the correct source in the reference list.
Skipping Citation Numbers
Do not leave gaps in numbering. Every new source should receive the next available number.

Is AMA only used in medicine?
Although it is most common in medicine and healthcare, AMA style is also used in related scientific and biomedical fields.
Should references be alphabetical?
No. AMA reference lists are arranged according to the order in which sources first appear in the document.
