Reference sections do not work well online as they involve a lot of scrolling for users, who can easily lose their place. They should be avoided where possible. Using hyperlinks within your text is best practice for web writing and helps users get to any information they need without having to scroll.
Only include a references section if the publications you need to reference are offline and cannot be linked to. If there are only a couple of offline references that you need to link to, include these as footnotes to the relevant section rather than as a separate section. This keeps the reference with the content it relates to and prevents users having to scroll, but avoid using footnotes where possible as they are not very accessible.
Follow our guidance for writing accessible reference sections if your users need you to include one.
