Template:SfnRef/doc
 | This is a documentation subpage for Template:SfnRef. It may contain usage information, categories and other content that is not part of the original template page. |
 | This template is used on approximately 139,000 pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This template uses Lua: |
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[1] 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.[2]
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 {{SfnRef}} and specify the same parameters as used with {{Sfn}}:
{{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 {{Sfn}} template code and change the name of the template from "Sfn" to "SfnRef". If your short footnote includes page numbers such as {{Sfn|Rolling Stone|2004|p=48}}, you can copy and paste it to create {{SfnRef|Rolling Stone|2004|p=48}}; 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 ({{Cite journal}}, {{Cite book}}, {{Cite web}}, etc.) and the generic Citation Style 2 template {{Citation}}.[9] It is intended to be paired with {{Sfnp}}, {{Sfn}}, {{Harvp}}, {{Harvnb}}, and related templates, and uses the same arguments. As explained above, {{SfnRef}} is only necessary in a subset of the cases where those are used.
{{Sfnp}} 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 {{SfnRef}} 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 {{SfnRef}} 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 {{Sfnp}}, etc., interpret the anchor ID string which is normally auto-generated.
The {{Vcite journal}} etc. templates (with Vcite, not Cite names) require the use of {{SfnRef}} to work with {{Sfn}}, {{Harvnb}}, and related templates.
Consistent output: For use with CS1/CS2 templates, {{Sfnp}} and its {{Harvp}} companion produce the most consistent citation formatting. For use with Vancouver citation templates (and any other citation styles that do not put dates in parentheses/round-brackets), the matching short-footnote templates are {{Sfn}} and {{Harvnb}}.

Notes
- ^ Such as
{{Sfnp}},{{Sfn}},{{Harvp}}, and{{Harvnb}}. - ^ This is includes the Vancouver style templates, {{Cite comic}}, and {{Cite court}}. Hand-written citations can be assigned an anchor with the {{wikicite}} template.
- ^ This anchor would be created automatically in CS1 citation templates using
|last=Smithand|date=2024in the full citation.|author=works the same as|last=. If neither "last" nor "author" are used,|editor=or|editor-last=will be used to create the anchor. If none of these parameters are used, the anchor must be created manually. - ^ This anchor would be created automatically in CS1 citation templates using
|last1=Doe,|last2=Pérez, and so on, along with|Date=2024in the full citation. - ^ This anchor would be created automatically in CS1 citation templates using
|Author=Anonymous. - ^ This anchor would be created automatically in CS1 citation templates using
|date=n.d.in the full citation. - ^ This anchor would be created automatically in CS1 citation templates leaving
|date=blank in the full citation. - ^ This anchor would be created automatically in CS1 citation templates using
|date=n.d.and|title=[Description]in the full citation. - ^ As well as
{{Vcite journal}},{{Vcite journal}},{{Vcite book}}and other templates that generate Vancouver system references;{{cite comic}}for comics;{{cite court}}for U.S. court cases; and{{wikicite}}which wraps around handwritten citations.
