This is the Vancouver style for referencing, used at the Univerity of Portsmouth within the School of Pharmacy and Biomedical Sciences and the Radiography departments.
This guide is modelled on Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers (2nd edition). You may wish to consult this source directly for additional information or examples.
Before referencing your webpage, determine that the item you are quoting cannot be cited alone as an electronic book, journal article etc.
Make sure that the item you are quoting is not a homepage. If you are referencing a homepage or a whole website, see the referencing a website pages.
Webpages can be volatile and subject to unannounced change. Whenever possible the URL you give should be a stable URL and link directly to the webpage itself. A stable URL, also known as a 'permament link' is more likely to remain accessible. To check if a link to a URL is stable, paste the link into the address bar of an Internet browser to make sure that it works. If there is no stable URL for the item, give the homepage of the website.
When citing organizations that are national bodies such as government agencies, if a nationality is not part of the name, place the country in parentheses after the name, using the two-letter ISO country code
For example: Department of Health (GB).
