AMA Format: Complete Citation Guide (2026)

AMA Format: Complete Citation Guide (2026)

Introduction

The AMA format is the American Medical Association citation style used widely in medicine, health sciences, and biomedical journals. It emphasizes numbered, sequential citations and a concise reference list designed for clarity in clinical and research writing.

Medical students, researchers, clinicians, and journal authors typically use AMA style for manuscripts, reports, and patient-care documentation. This guide gives up-to-date (2026) rules, step-by-step examples, and practical tips — plus a quick link to Rephrasely's free citation generator to speed your workflow: Rephrasely Citation Generator.

General Rules

• Number citations in the order they appear in the text using Arabic numerals in superscript (no parentheses).
• Place the citation number after punctuation when practical: after commas and periods, but before colons and semicolons if clarity requires.
• List references in numeric order at the end of the document (not alphabetical), and use the same number for repeated citations.
• Abbreviate journal names per PubMed/MEDLINE conventions; provide DOI whenever available.
• Use plain, consistent punctuation and spacing. AMA is strict about commas, periods, and abbreviation formats.

How to Cite by Source Type

Below are step-by-step templates and examples for common source types. Use the templates to construct citations manually or plug data into Rephrasely's free citation generator to automate formatting.

1. Book (single author)

Template: Author(s). Title of Book. Edition (if not first). Publisher; Year.

Example:

2. Chapter in an Edited Book

Template: Author(s) of chapter. Title of chapter. In: Editor(s), ed(s). Title of Book. Edition (if not first). Publisher; Year:page range.

Example:

3. Journal Article (print or online with DOI)

Template: Author(s). Article title. Journal Name. Year;Volume(Issue):page range. doi:DOI

Example:

4. Website or Webpage

Template: Author(s) (if available). Title of webpage. Name of Website. Published date. Updated date (if applicable). Accessed Month Day, Year. URL

Examples:

5. Government or Agency Report

Template: Name of Agency. Title of Report. Report number (if any). Publisher (if different). Year. Accessed Month Day, Year. URL

Example:

6. Conference Proceedings or Abstract

Template (proceedings): Author(s). Title. In: Editor(s), ed(s). Title of Proceedings; Date(s) of Meeting; Location. Publisher; Year:page range.

Example (abstract):

Quick tips for multiple authors

List up to six authors in full. If there are more than six authors, list the first three followed by "et al." (AMA recommends listing up to six, but many journals now list all; check the target journal).

In-Text Citations

Use superscript Arabic numerals in sequential order the first time a source is cited.

Single citation example:

Recent studies show improved outcomes with early mobility therapy.¹

Multiple citations should be comma-separated, and ranges should use a hyphen:

See prior work for anesthetic dosing guidelines.^1,3,5-7

If you cite the same source again, use the original number assigned the first time it appeared.

Reference List

Place the reference list at the end of the document under the heading "References" or "Reference List." Number each entry in the order cited in the text.

Formatting rules:

• Use a hanging indent for each reference entry.
• Do not use bold or italics unnecessarily; italicize book and journal titles only.
• Abbreviate journal titles per the National Library of Medicine.
• Include DOI in the format doi:10.xxxx when available.

Example reference list (numbers match in-text citation order):

1. Smith J. Clinical Pharmacology. 3rd ed. Health Press; 2021.
2. Garcia M, Wong T, Allen K. Telemedicine outcomes in rural clinics. J Telemed Health. 2024;30(4):210-217. doi:10.1234/jth.2024.0012
3. World Health Organization. Global influenza surveillance and response. WHO. Published March 10, 2025. Accessed January 12, 2026. https://www.who.int/flu-surveillance
4. Centers for Disease Control and Prevention. National Diabetes Statistics Report, 2023. CDC; 2023. Accessed February 1, 2026. https://www.cdc.gov/diabetes/data
5. Doe A, Lee R. Fluid management in critical care. In: Brown P, Patel S, eds. Critical Care Essentials. 2nd ed. MedPublish; 2023:45-62.

Common Mistakes

• Incorrect numbering order. Reordering paragraphs without updating citation numbers creates mismatches. Fix by renumbering sequentially or use your word processor's reference manager.
• Using author-date instead of numeric superscripts. AMA does not use parenthetical (Author, Year) citations. Replace author-date citations with superscript numbers.
• Improper journal abbreviations. Use PubMed/NLM title abbreviations. If unsure, check the NLM Catalog or use Rephrasely's citation generator to auto-format journal titles.
• Missing DOI or access dates for online items. Always include DOI when available and an access date for webpages without publication dates.

Practical Workflow Tips

1) Create citations as you draft. Assign numbers the first time a source appears and use the same number for repeats.

2) Use Rephrasely's free citation generator to produce properly formatted references quickly. Copy the output into your reference list and ensure numbering matches your in-text citations.

3) Run your manuscript through tools for quality control: Rephrasely's plagiarism checker to verify originality, AI writer (Composer) to draft clean prose, and the AI detector to check generated content when required by journals.

4) Keep a final pass to check journal-specific submission requirements — journals using AMA may have small house-style differences.

Frequently Asked Questions

Do I need to include DOIs in AMA citations?

Yes. Include the DOI when available using the format doi:10.xxxx. If there is no DOI and the article is online only, include the URL and an access date if no publication date is clear.

How do I cite the same source multiple times in AMA?

Use the original superscript number assigned at first mention for each subsequent citation. Do not assign new numbers for repeat citations; keep the sequence consistent throughout the document.

Can Rephrasely help me format an entire reference list?

Yes. Rephrasely's free citation generator can format individual citations in AMA style. For manuscript drafting and checks, combine the generator with the Composer, verify originality with the plagiarism checker, and use the AI detector if you used AI tools during writing.
