The full Citation Generator covers APA, MLA, Chicago, Harvard, AMA, ACS, IEEE, Vancouver, and the 10,000+ other styles in the CSL registry.
Paste a DOI, URL, or ISBN. Get back a clean reference in AMA style — the format used by JAMA and most clinical journals. Numbered references, abbreviated journal names, superscript in-text citation. Free, no signup.
Tip: Paste a URL, DOI, or ISBN for automatic metadata lookup.
AMA style is defined by the AMA Manual of Style, currently in its 11th edition (2020), published by the American Medical Association and the Oxford University Press. It's the working standard for JAMA and its specialty journals, and the default for clinical, biomedical, and translational research writing across the US. Most medical schools, residency programs, and clinical-research labs default to AMA for case reports, manuscripts, and grant applications.
1. Tversky A, Kahneman D. Judgment under uncertainty: heuristics and biases. Science. 1974;185(4157):1124-1131. doi:10.1126/science.185.4157.1124
AMA uses numbered superscript in-text citations. The first source cited gets 1, the second 2, and so on, with the same number reused every time that source is cited again. Numbers go after punctuation: ...antibiotic stewardship reduces resistance.1 Ranges and lists are compact: 1-3 or 1,4,7.
Antibiotic stewardship reduces resistance.1
References are numbered in the order they first appear, not alphabetized. Author names are surname plus initials, no periods between initials, comma-separated. Article titles use sentence case. Journal names use the official NLM-style abbreviation (N Engl J Med, not New England Journal of Medicine) and stay italicized. Year, volume, issue, page range follow in compact punctuation: 2020;383(2):109-118.
doi:10.xxxx with no space after the colon.Each input goes through the right source. DOIs hit Crossref directly, since that's where they're registered. ISBNs resolve through library and publisher records. URLs get scraped for embedded metadata (DOI in the source, OG tags, schema.org). If nothing's there, we fall back to Semantic Scholar and OpenAlex. Once the canonical record lands, the CSL engine renders the citation in AMA. That's the same engine Zotero and Mendeley run, the same one behind most journal submission portals.
AMA is the working standard for clinical journals, medical schools, residencies, and grant submissions. JAMA and most specialty journals require it. APA is rare in clinical writing — you'll see it in psychology and nursing journals, but biomedical and translational work defaults to AMA.
Reuse the same superscript number. If a paper is cited as 1 on page 2 and again on page 8, both citations get 1. Don't renumber on subsequent appearances.
The official NLM/MEDLINE abbreviations: N Engl J Med, JAMA, Lancet, BMJ, Ann Intern Med. The generator pulls the abbreviated form automatically — you don't need to look it up. PubMed's full-record view also lists the abbreviation for any journal.
doi:10.xxxx with no space after the colon. Not https://doi.org/10.xxxx the way APA 7 prefers, and not doi: 10.xxxx with a space.
Surname + initials, no periods between initials, comma-separated: Tversky A, Kahneman D. List the first six authors; for seven or more, list the first three followed by "et al."
Many journals publish their own house-style overlays on top of AMA — slightly different DOI formatting, or specific rules for supplementary materials. Submit in standard AMA and the journal's copyeditor will adjust to house style. Or pick the journal's specific CSL style from the More menu if it's in the registry.
