Learn how to cite arXiv, bioRxiv, and other preprint server papers in AMA format (11th edition). This guide includes the reference list format, in-text citation examples, and key formatting rules.

AMA Reference List Format

Here is the standard AMA format for citing a preprint in your reference list:

AMA In-Text Citation

Use one of these formats when referencing this source within your paper:

Parenthetical

Key AMA Formatting Rules

  • Name the preprint repository as the source, not a journal.
  • Use the wording "Preprint posted online Month Day, Year."
  • Include the DOI at the end (doi:xxxxx).
  • References are numbered in order of first citation.

Step-by-Step Guide

  1. Gather source information: Collect the author name, title, publication date, and URL or DOI for your preprint.
  2. Format the reference: Arrange the elements following the AMA (11th edition) template shown above.
  3. Create the in-text citation: Add a parenthetical or narrative citation in your paper where you reference this source.
  4. Add to your reference list: Include the full formatted citation at the end of your paper.
  5. Double-check formatting: Verify italics, punctuation, capitalization, and hanging indents match AMA requirements.
