Vancouver Style uses a notational method of referencing when referring to a source of information within the text of a document.
In its simplest form, a number in parentheses (round brackets) placed in the text of the essay, indicates the relevant reference:
Citations are numbered consecutively in the order in which they appear in the text and each citation corresponds to a numbered reference, containing publication information about the source cited, in the reference list at the end of the publication, essay or assignment.
Once a source has been cited, the same number is used in all subsequent references. No distinction is made between print and electronic references when citing within the text.
A numbered list of references must be provided at the end of the paper:
The list should be arranged in the order of citation in the text of the publication, assignment or essay, not in alphabetical order.
List only one reference per reference number.
See Reference List Entries or All Examples for details on how to construct references for specific resources such as books, journals and web pages.
Please note: that this guide has been modified to reflect updates to Vancouver referencing style published in the Uniform requirements for manuscripts submitted to biomedical journals: writing and editing for biomedical publication (December 2018).
Significant change: In text citations should now be placed in parentheses (round brackets).
Additional examples: This guide now includes examples for referencing datasets.
