How to write your reference list and bibliography in the Vancouver style
Your lecturers consider accurate and consistent referencing to be an important part of your academic work. Check your course guidelines so you know which referencing style to use.
The following examples are in two parts:
- the information you should collect about each piece of work you use
- how this information is presented when you write a full reference
If you cannot find the type of work you need to provide a reference for, please contact your librarian for more help.
In general, if no author is provided or the author is unknown, begin with the title, followed by the year.
Click on the type of work you need to provide a reference for. If you cannot find the type of work you need, please contact your librarian for more help.

Please refer to Imperial Generative AI tools guidance as well as your tutor(s) for guidance on using generative AI tools for assessed work. You must provide clear and accurate information for any sources you use in your work.
Depending on the generative AI tool you use, the content may be nonrecoverable when it cannot be retrieved or linked to. Note: as of June 2023, you can generate a shareable link to a ChatGPT conversation and we recommend you do so for use in references.
You should also acknowledge your use of generative AI tools for all assessed work. Follow the guidance provided on the library’s Generative AI guidance page.
Information about using and referencing ChatGPT and other generative AI tools in assignments will continue be updated. Check this section regularly for any changes in our advice. (Last update: 29 Nov 2023)
Example 1: You have generated a shareable link
Reference list:

In-text citation:
Each piece of work cited in your text should have a unique number, assigned in the order of citation. If, in your text, you cite a piece of work more than once, the same citation number should be used. You can write the number in brackets or as superscript.
