Vancouver Reference Builder
A Vancouver reference builder formats references in the numeric system set by the International Committee of Medical Journal Editors (ICMJE) and the NLM's Citing Medicine guide — sources are numbered in the order they're cited, with each in-text reference shown in parentheses. It's the standard citation format for biomedical and clinical journals worldwide. Search by title, DOI, ISBN, or URL, confirm the match, and get a numbered reference plus its in-text marker.

This Vancouver reference builder formats sources in the style that takes its name from a 1978 meeting of medical journal editors in Vancouver, today formalized by the International Committee of Medical Journal Editors (ICMJE) and documented in the NLM's Citing Medicine guide. It numbers sources in the order they're first cited, lists authors by last name and initials with no punctuation between them, and abbreviates journal names where a standard abbreviation exists. Run a journal article, a book, or a website through this Vancouver reference builder and each comes back in the same numbered format.
This Vancouver reference builder builds the reference-list entry and its parenthetical in-text number directly from the NLM/ICMJE citation-sequence rules, encoded in the open Citation Style Language (CSL) that Zotero also uses. Search by title, DOI, ISBN, or URL and this Vancouver reference builder pulls in a source automatically; confirm it's the right one, or type the details in by hand and the Vancouver reference builder still returns the same correctly numbered result.
Who uses Vancouver style
Vancouver style is the citation format required by most biomedical and clinical journals worldwide, following the ICMJE's "Uniform Requirements for Manuscripts Submitted to Biomedical Journals." If a journal's author guidelines say "Vancouver style," "NLM style," or "ICMJE recommendations," a Vancouver reference builder keeps every numbered entry consistent with those rules across a long reference list.
