The Vancouver referencing style uses numerical citations throughout a document and a Reference List at the end. It was created in 1978 at the International Committee of Medical Journal Editors conference in Vancouver, and has come to be known as the Vancouver style. Vancouver, is a "numbered" style, and follows the rules established by the International Committee of Medical Journal Editors.
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.
