Template:SfnRef/doc

{{#invoke:Message box|mbox}} {{#invoke:High-use|main|1=|2=|info=|demo=|form=|expiry=|system=}} {{#invoke:Shortcut|main|template=yes}} {{#invoke:Lua banner|main}}

This template creates an identifier that is used as a link anchor for short citations. Many articles are cited with shortened footnotes, which usually link to full citations at the bottom of the page. {{SfnRef}} accepts the same parameters as most short citation templates and create matching anchors when used in the |ref= parameter of the full citation. Most {{cite xxx}} templates will automatically generate the anchor, or landing point, for links. The anchor can be created manually in situations where the automatic anchors would cause issues including:

• Multiple authors with the same last name
• No known last name for the author
• Unusual characters in the author field
• Multiple works in the same year by the same author
• Year of publication unknown

Additionally some less commonly used citation templates, and all full citations written by hand can only be linked to with a manually created anchor.

Examples

When citing an article published in the December 2004 edition of Rolling Stone where the author is unknown, you might create a short footnote as follows:

{{Sfn|Rolling Stone|2004}}

You may code the value for the |ref= parameter manually, or you can use {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}} and specify the same parameters as used with {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}}:

{{SfnRef|Rolling Stone|2004}}

The full footnote:

{{Cite news |work=[[Rolling Stone]] |title=The RS 500 Greatest Songs of All Time |ref={{SfnRef|Rolling Stone|2004}} |date=December 2004}}

You can copy and paste the {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}} template code and change the name of the template from "Sfn" to "SfnRef". If your short footnote includes page numbers such as {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}}, you can copy and paste it to create {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}}; the |p=48 parameter is not necessary but will do no harm.

Usage

{{SfnRef|Name|Year}}
{{SfnRef|Name 1|Name 2|Name 3|Name 4|Year}}

The template accepts up to four names and a year of publication. If there are more than four authors, list only the first four. The last parameter is the year of publication, optionally with a letter suffixed if there are multiple citations by the same set of authors in the same year. All named parameters, such as |p= are ignored.

Purpose

This template creates the proper value for the |ref= parameter of Citation Style 1 templates ({{#Invoke:Template link general|main|code=on}}, {{#Invoke:Template link general|main|code=on}}, {{#Invoke:Template link general|main|code=on}}, etc.) and the generic Citation Style 2 template {{#Invoke:Template link general|main|code=on}}. It is intended to be paired with {{#Invoke:Template link general|main|code=on}}, {{#Invoke:Template link general|main|code=on}}, {{#Invoke:Template link general|main|code=on}}, {{#Invoke:Template link general|main|code=on}}, and related templates, and uses the same arguments. As explained above, {{#Invoke:Template link general|main|nolink=yes|code=yes}} is only necessary in a subset of the cases where those are used.

{{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}} and its variants create a short footnote that is linked to a full footnote. The templates create the link automatically, but the full footnote must be assigned the proper ID value to be a valid target for that link. This usually happens automatically using the full-citation template's author/editor and date/year parameters, but some cases need a custom anchor, and that is what {{#Invoke:Template link general|main|nolink=yes|code=yes}} is for.

When using the Citation Style 1 and 2 family of citation templates, a default ID is generated from the last names of the first four authors (or editors if there are no authors specified). However, if none of |last=, |author=, |editor-last=, or their equivalents are present, use {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}} inside the CS1/CS2 template's |ref= parameter to create a link anchor (perhaps using the publisher name or work title or an abbreviation thereof) without having to know the rules for how {{#Invoke:Template link general|main|nolink=yes|code=yes|nowrap=yes}}, etc., interpret the anchor ID string which is normally auto-generated.

Consistent output: For use with CS1/CS2 templates, {{#Invoke:Template link general|main|code=on}} and its {{#Invoke:Template link general|main|code=on}} companion produce the most consistent citation formatting. For other citation styles that do not put dates in parentheses or brackets, matching short-footnote templates include {{#Invoke:Template link general|main|code=on}} and {{#Invoke:Template link general|main|code=on}}.
