Description
This template links Wikipedia articles to various library (and other) catalogue systems, for biographies and other topics.
This template draws its values from Wikidata. A pencil icon 
gives convenient access to the "Identifiers" section of the corresponding Wikidata item.
Empty instances
If there is no information in Wikidata for the specific subject, an empty instance of this template will be dormant, meaning it will be invisible on the rendered page. Thus, using this template on a page with no authority information is harmless. An empty instance of this template stays dormant in an article, until values are added to Wikidata, when it will then display them.
Validation
The template attempts to validate digits for all values and shows an error if the check fails.
Position
As a metadata template, the Authority control template should be placed on a new line, after the external links section and navigation templates, immediately before the categories.
Usage
- {{Authority control}}
As a general guideline:
- Insert the empty version
- Click "Show preview" to see which sources are automatically pulled from Wikidata
- If you know of more sources, add those sources to the article's Wikidata item, so that other language versions of Wikipedia will automatically benefit.
Suppression of identifiers
Identifiers can be selectively suppressed via the |suppress= parameter. For example:
- {{Authority control |suppress=VIAF,LCCN,WORLDCATID}}
Specifying the Wikidata item
If a page is not connected to a Wikidata item (for example, a page in draft space, user space or project space), you can specify the appropriate item to draw data from, by using the |qid= parameter.
- {{Authority control |qid=Q49605590}}
To find the correct item, you can search the database. If there is not yet an existing item, you can create a new item.
As soon as the page is connected to a Wikidata item, this parameter will be ignored so you can remove it from the template.
Additional Wikidata items
In some cases, you might need to specify additional items to draw data from. For example,
- Bonnie and Clyde also draws data from (Q2319886) and (Q3320282)
- North Rona also draws data from (Q28831543)
To specify additional items, you can use the |additional= parameter. For example:
{{Authority control | additional = Q2319886, Q3320282}}
Whitelists
A number of whitelists are configured, which allow only a limited selection of identifiers to be displayed. These can be used with the |show= parameter. For example, including |show=arts will only show identifiers which have identified as particularly relevant to the arts.
|country= can be used as an alias for |show= (but they can't both be used simultaneously).

Rendering
The template is split into a number of sections, including "International", "National", "Academics", "Artists" etc. The template usually displays as a navbox with a header:
If all identifiers are in the same section, |state= is ignored, and the template displays on one line.
If you use additional qids to draw data from additional wikidata items, then a new section will be added for each. In this case, the identifiers will not be separated further:
Initial visibility: currently defaults to autocollapse
To set this template's initial visibility, the |state= parameter may be used:
|state=collapsed:{{Authority control|state=collapsed}}to show the template collapsed, i.e., hidden apart from its title bar|state=expanded:{{Authority control|state=expanded}}to show the template expanded, i.e., fully visible|state=autocollapse:{{Authority control|state=autocollapse}}
If the |state= parameter in the template on this page is not set, the template's initial visibility is taken from the |default= parameter in the Collapsible option template. For the template on this page, that currently evaluates to autocollapse.
Microformat
The template wraps each UID value with the HTML markup: <span class="uid">...</span>, which enables the first-found value to be included in an hCard microformat.
List of identifiers
The template gets its information from the following properties on Wikidata: Lua エラー モジュール:Authority_control/documentation 内、69 行目: attempt to index field '?' (a nil value)
Additional tracking categories
This template may add the following categories:
- Category:Pages with authority control identifiers needing attention (2) – category to track error
- Category:Pages using authority control with parameters (0) – IDs should be migrated to Wikidata
