Vancouver Referencing

Basic instructions on how to reference using the Vancouver system

Vancouver - this guide and further resources

The Vancouver referencing style is a numeric system commonly used in biomedical, health and some science journals (1, p. 248). 


The Vancouver referencing style is used by MBBS students at St George's.  This guide gives brief examples of how to cite within the text and how to write references using the Vancouver style.  The information in this guide is based on Cite them Right (12th edition) which is endorsed by St George's. This book contains many more types of referencing examples so if you don't find your example in this guide, use Cite them Right. 


Use the online version (you will need to log in with your St George's username and password) or find it on the library shelves at PN171 PEA.  Further samples of referencing formats can also be found in the National Library of Medicine's Citing Medicine publication (2), which is also recommended by Cite them Right (1).


This guide will show you how to reference:

  • Books and ebooks

  • Journals and ejournals

  • NICE Guidelines and other regulations and protocols

  • Cochrane Library systematic reviews

  • Webpages
  • Information from Canvas
