Overview[edit]

Further information: Help:Footnotes

A footnote used multiple times may be defined with a name:

<ref name="foo">content</ref>

To invoke a named footnote:

<ref name="foo" />

References may also be defined within the reference list:

{{reflist|refs=
<ref name=rename1>refcontent1</ref>
<ref name=rename2>refcontent2</ref>
}}

List-defined reference may be within groups:

{{reflist|refs=
<ref name=rename1>refcontent1</ref>
<ref name=rename2 groupname=groupname>refcontent2</ref>
}}

List-defined references may be invoked by the standard markup or by use of {{r}}.

Issues and resolution[edit]

  • A list-defined reference uses a group name that is not used within any <ref>...</ref> tags.
  • An explanatory note template such as {{efn}} is used inside <ref>...</ref> tags; use {{refn}} instead of <ref>...</ref> tags.

Examples[edit]

The reference list has a defined reference with a group named note, but there is no reference in the content with that group and name.
