AMA Manual of Style


AMA Manual of Style: A Guide for Authors and Editors is the style guide of the American Medical Association. It is written by the editors of JAMA and the Archives journals and is most recently published by Oxford University Press. It specifies the writing and citation styles for use in the journals published by the American Medical Association. The manual was first published in 1962, and its current edition, the 11th, came out in 2020. It covers a breadth of topics for authors and editors in medicine and related health fields. The online edition also has updates, a blog, monthly tips from the editors, quizzes, and an SI unit conversion calculator.
AMA style is widely used, either entirely or with modifications, by hundreds of other scientific journals, in many textbooks, and in academia. Along with APA style and CSE style, it is one of the major style regimes for such work. Many publications have small local style guides that cascade over AMA, APA, or CSE style.

    Traits of AMA style

In general, AMA style strives for clarity and simplicity, and trusts the target readership to have a certain amount of knowledge and education. For example, AMA style dispenses with periods in abbreviations, on the grounds that they are unnecessary for meaning's or clarity's sake in all but very few contexts. AMA also requires expansion of most abbreviations at first use, for clarity's sake. The AMA Manual of Style sets standards for mechanical style, but does not insist on invariability for its own sake in contexts where a bit of limited variation is logical, especially in higher-level style.
