==Anchor IDs==
This template generates an HTML IDd as an anchor to link the short citation to the full citation.. The {{para|ref|harv}} field is necessary in each of the <syntaxhighlight lang="wikitext " inline>{{cite ...}}</syntaxhighlight> templates to enable the id. The {{tl|citation}} template always generates an id.

If the article cites multiple works by the same author in the same year, then duplicate IDs will be generated. One method to resolve this is to add an alpha suffix to the year. Example: 2009a, 2009b, 2009c.

If works are cited where the author or year is unknown— such as for a web page —then an invalid ID will be generated. To resolve this, create a custom ID:

: <syntaxhighlight lang="wikitext " inline>{{sfn|cite name|year}}</syntaxhighlight>
: <syntaxhighlight lang="wikitext " inline>{{cite ... |ref=CITEREFcite_nameyear }}</syntaxhighlight>

Where ''cite_name'' is a name such as the publisher, and must follow these rules:
*  Must begin with a letter A-Z or a-z
* Can be followed by: letters (A-Za-z), digits (0-9), hyphens ("-"), underscores ("_"), colons (":"), and periods (".")
* Spaces in the {{para|ref}} field must be replaced with underscores
* Case-sensitive

===SfnRef===
{{main|Template:SfnRef}}
使用{{tl|SfnRef}}生成{{tl|cite}}系列模板中{{para|ref}}所需要的参数。保证{{tl|sfn}}和{{tl|SfnRef}}中使用同样的值（主要是作者和年份，SfnRef中书籍页数通常不填）：
<!-- You may use the {{tl|SfnRef}} template to generate the proper value for the {{para|ref}} parameter. Pass the same parameters used with {{tl|sfn}} to {{tl|SfnRef}}: -->
: <syntaxhighlight lang="wikitext " inline>{{sfn|cite name|year}}</syntaxhighlight>
: <syntaxhighlight lang="wikitext " inline>{{cite ... |ref={{SfnRef|cite name|year}} }}</syntaxhighlight>

Articles using {{tlx|sfn}} should be checked for duplicate IDs with the [http://validator.w3.org/ W3C Markup Validation Service].
