Vancouver citation examples by source type

The ICMJE format: surname then initials with no punctuation, sentence-case title, journal abbreviation without italics, then year, volume, issue and pages.

More than six authors

List the first six names, then et al. This is the most common difference from AMA, which stops at three.

Common Vancouver citation mistakes

  • Using the AMA three-author rule Vancouver names the first six authors before et al. Three is AMA.
  • Dropping the city from a book reference That is the AMA 11th edition change. Vancouver still wants City: Publisher; Year.
  • Spelling journal names out in full Use the NLM abbreviation, which is what PubMed shows on the record.
  • Writing the full closing page number Vancouver shortens it: 100-10, not 100-110.
  • Alphabetising the reference list The list follows citation order. Sorting by author renumbers every citation in the text.
  • Omitting [Internet] and the cited date Journals following ICMJE strictly want both, plus "Available from:" before the URL.

Vancouver citation generator FAQ

Is this Vancouver citation generator free?

Yes. Generate, copy, save, and export Vancouver citations without signing up. There is no paid tier and no export limit.

Is Vancouver the same as AMA?

They are close relatives, not the same style. Both number sources in citation order and write author names as Doudna JA. Vancouver names six authors before et al. and keeps the place of publication in book references; AMA names three and dropped the city in its 11th edition.

Parentheses, brackets or superscript?

All three are used. The ICMJE Recommendations leave the marker to the journal, so check the author guidelines for where you are submitting and stay consistent throughout.

How do I abbreviate a journal name?

Use the NLM abbreviation, which appears on every PubMed record and in the NLM Catalog. If you paste a PubMed ID into the generator, we take the abbreviation straight from the record.

Can I cite by PubMed ID?

Yes. Paste the PMID and we pull the record from PubMed, which covers most biomedical articles, including older ones with no DOI.

Where does the citation metadata come from?

PubMed for biomedical literature, Crossref for DOIs, and Open Library for ISBNs. Nothing is written by a language model, so a volume or page range is either verified or left blank for you to fill in. See our methodology.
