Template:Listref/doc

For the use of standard footnotes with labels such as lower-alpha, see WP:CITELABEL.

This template creates in-text citations and a reference list for use in list articles as a supplement to the standard footnote system. It is intended for use only for references used a large number of times. The template is styled to render in-text citations and the reference list like the <ref> tags and {{reflist}} template used by the footnote system.

Differences:

• There is no backlink from the citation in the reference list, by design.
• The in-text citation uses a standard HTML link without an id, by design. Other templates create an HTML id, which is only allowed to be defined once, thus multiple uses of the same in-text citation results in invalid HTML
• The in-text citation link and the anchor in the reference list are created manually.

Likenesses:

• In-text citations use the same style.
• The reference list uses the same marking and font size.
• The citation in the reference list is highlighted when the in-text citation is followed.
• The reference list can be formatted with columns like {{reflist}}.

The problem

List articles often use a single named reference a large number of times. Each use creates a backlink in the reference list entry and eventually the backlinks become ugly and useless. For example:

1. ^ ^{a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad ae af ag ah ai aj ak al am an ao ap aq ar as at au av aw ax ay az ba bb bc bd be bf bg bh bi bj bk bl bm bn bo bp bq br bs bt bu bv bw bx by bz ca cb cc cd ce cf cg ch ci cj ck cl cm cn co cp cq cr cs ct cu cv cw cx cy cz da db dc dd de df dg dh di dj dk dl dm dn do}

Examples:

• List of Eagle Scouts
• List of islands of Maine
• List of philosophers (A–C)

In-text citation

{{listref}} creates the in-text citation link using the first unnamed parameter. This will define both the superscript callout text (^[a]) and the link id (#CITEREFa). If undefined, it defaults to a.

Examples:

• {{listref}} shows as ^[a]
• {{listref|b}} shows as ^[b]
• {{listref|ii}} shows as ^[ii]

Although any characters can be used, only these styles will link to citations in the reference list:

• lower-alpha
• upper-alpha
• lower-roman
• upper-roman
• lower-greek
• decimal

To include a page number use |p=

• {{listref|a|p=10}} shows as ^[a]

Reference list

The citations are defined in and the reference list is displayed with {{listref/reflist}}. There are two named parameters for up to nine citations:

• |id1= through |id9= matches the link id set with {{listref}}.
• |ref1= through |ref9= defines the full citation.

{{Listref/reflist}} supports style parameters similar to {{reflist}}:

• Columns: Using {{listref/reflist|30em}} will automatically choose the number of columns based on the width of the web browser. You can set this to match the columns parameter in {{reflist}}.
• List style: The reference list is styled as lower-alpha by default. It can be changed with |liststyle= to:
  • upper-alpha
  • lower-roman
  • upper-roman
  • lower-greek
  • decimal

The style must match the in-text link id style.

{{listref/reflist
|id1=a |ref1=Reference a
|id2=b |ref2=Reference b
}}

Citations in the reference list must be in the proper order for the superscript links to function.

Freestyle

You can use any text for the label by setting |liststyle=square. The reference list will show as an unordered list and the label will show in the reference list at the beginning of each entry enclosed by brackets.

Troubleshooting

With manual links it is easy to introduce errors such as duplicate anchors and unused references. The script User:Trappist the monk/HarvErrors will show many related errors. Duplicate anchors may be found by using the W3C Markup Validation Service.

MediaWiki:ListrefErrors.js

After installing the script, errors should show in this test:

• In-text use of {{listref}} that does not link.^[x]

Bug

The issue with over-backlinking has been reported as T25455 Cite extension: suppress backlink. If the extension is updated, then this template should be deprecated.
