The information contained within these pages is intended as a general referencing guideline.
Please check with your supervisor to ensure that you are following the specific guidelines required by your school.
This guide provides you with examples of how to correctly cite references in the Vancouver style within the text of your assignments.
The Vancouver system does allow for some variations in style, but you must remain consistent throughout your document. The Vancouver system is most commonly used in medical and clinical sciences.
Citations you include in the main body of your writing should only provide a number that refers to the reference that you are citing. These citations will then link to a fully detailed reference, which will be included in your list of references / bibliography.
The way in which you refer to a source within the text of your work should always follow this format:
If the author’s name forms a natural part of your sentence, then the surname should be followed by the number indicating the order that it appears in the document (in brackets), eg.
Albanese refers to problem based learning as...(1)or
Albanese refers to problem based learning as...(1)
If you do not mention the author’s name within your text, you should place the number in brackets at the end of the sentence, eg.
There are six distinctive conditions, which need to be satisfied, in order for a whistle-blowing case to be justified. (2)
You can always cite within the sentence structure providing it does not interfere with the flow of the sentence, eg.
There have been efforts to replace mouse inoculation testing with in vitro tests, such as enzyme linked immunosorbent assays (23) or polymerase chain reaction (6), however these remain experimental.
Provide the numbers in brackets as they appear in the text after these sentence, eg.
Several drug trials proved that the antibody was released immediately. (2, 3, 9- 12)
There is currently no agreement among citation authorities as to the use of page numbers with in-text citations in Vancouver style. If you have been asked to include page numbers for direct quotations by your school, we recommend using one the following formatting methods:
Peterson (1, p. 20) discusses two examples of...
Peterson 1 (p. 20) discusses two examples of...
Any quotations used should be relevant to the argument you are making. Short quotations (1-2 lines) can be set in quotation marks and included within the body of the text.
Your reference list links with your in-text citations, enabling readers to easily trace the sources cited within your work. It is a list of the documents from which any direct quotations or examples have been taken.
N.B. A bibliography (where you give credit to sources that were used for background reading, but were not quoted within the body of the text), is not usually required. You should however always check this first, with the person who will be assessing your work.
Your reference list (and bibliography if you choose to provide one) should be arranged numerically in the order that the citations appear in the text.
If you have up to six authors for a reference then you list all the authors in your reference list, If you have more than six than six, list the first six authors followed by the term 'et al,' .
Different types of publication require different amounts of information. The Vancouver system lays down standards for the amount of information required for each document type; these are detailed below.

It can often be difficult to identify the author of a web-page. If this is the case use the organisation (e.g. BBC) in place of the author. If a website has no discernible author or organisation you may want to strongly consider whether it is suitable for inclusion in a piece of academic writing! Again it is probably best to check with the person who will be assessing your work, if you find yourself in this situation.
