This page, Help:Reftags, explains the use of the reftag element,<ref>...</ref> for defining reference footnotes, as displayed by using a <references /> tag or a ((Reflist)) template to list the footnotes. A reftag can also be defined by using wikitext function ((#tag:ref|...)) to generate the text <ref>...</ref> and allow direct use of subst'ing of templates to embed equivalent markup inside a footnote, or to nest a <ref>...</ref> inside a ((#tag:ref|...)).

Defining a reftag element[edit]

The general format is <ref>text</ref> for a simple reftag footnote. However reftags can have a name="xx" to define a footnote to be reused on a page by named ref, <ref name="xx" />, as when citing the same webpage at several spots in the article text. There can be more than 3,000 reftag footnotes defined on a page, but usually there are less than a hundred.[fn 1]

Citing different pages in a single source

When citing different pages in a single source, a named ref[1] can be followed by a ((R)) template. Given a ref like "<ref name="author1990">book</ref>", the ref "author1990" can be reused, now using a different page number, say 53. This subsequent ref ((R|author1990|p=53)) will show the same superscript number, with a suffix of a colon and, in this case 53, the page number.[1]: 53  This format allows the reader to click to the reference section, and then click on other references from the same source.

Named groupings

Rather than define hundreds of footnotes in a single list, various reftags could split to some named groupings, such as using "<ref group="gg">...</ref>"" to collect those footnotes into group name "gg" as displayed by <references group="gg" />.[fn 2] For example, a common tactic is to define footnote group "fn" which shows each link as "[fn 9]" for the 9th footnote in the group="fn". A group name can be multiple words in straight double quotation marks (group="set xx yy"), but a single-word name with no punctuation or other special characters, just ASCII letters and numerals, can omit the quotation marks (as: group=fn). Hence, many group names are typically one-word labels, to avoid excessive quotation marks.[fn 3]

Defining a reftag function[edit]

Rather than using an element <ref>text</ref>, an alternate method is to use the wikitext function tag:ref, as ((#tag:ref|...text...)) to define the contents of a footnote.


Footnotes (fn)[edit]

  1. ^ A reftag formats extremely fast, but users can become overwhelmed with more than 500 footnotes on a page.
  2. ^ This is a sample footnote in group="fn".
  3. ^ This footnote uses double-quotes in name group="fn".
