== Description ==
{{details|Authority control|Wikipedia:Authority control}}
This metadata template links Wikipedia articles to various library catalogue systems, for biographies and other topics.

This template draws most of its values from [[Wikidata]], but they can be overridden by locally entered data. Adding the data to Wikidata is preferable.

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, so this template should be added to all biographies, whether or not there are authority control identifiers in Wikidata already.

=== User pages ===

The template may also be placed on user pages, but then data must be entered locally.

== Data types ==

; Supported authority files:
: [[Virtual International Authority File]] (VIAF)
: [[Library of Congress Control Number]] (LCCN)
: [[International Standard Name Identifier]] (ISNI)
: [[ORCID|Open Researcher and Contributor ID]] (ORCID; see also [[WP:ORCID]])
: [[Integrated Authority File]] (''{{lang|de|Gemeinsame Normdatei}}'' or GND)
: [[LIBRIS]] by the [[National Library of Sweden]] (SELIBR)
: [[Système universitaire de documentation|University Documentation System of France]] (''{{lang|fr|Système universitaire de documentation}}'' or SUDOC)
: [[Bibliothèque nationale de France|National Library of France]] (''{{lang|fr|Bibliothèque nationale de France}}'' or BNF)
: [[Biografisch Portaal|Dutch Biography Portal]] (''{{lang|nl|Biografisch Portaal}}'' or BPN)
: [[ResearcherID]] (RID)
: [[BIBSYS]] (BIBSYS)
: [[Union List of Artist Names]] (ULAN)
: [[MusicBrainz]] Artist ID (MBA)
: [[National Library of Australia]] (NLA)
: [[National Diet Library]] (NDL)
: … (30+ sources, see "local conf" list at [[Module:Authority control]])

; Deprecated:
: [[Corporate Bodies Authority File]] (''{{lang|de|Gemeinsame Körperschaftsdatei}}'' or GKD), now part of GND
: [[Name Authority File]] (''{{lang|de|Personennamendatei}}'' or PND), now part of GND
: [[Subject Headings Authority File]] (''{{lang|de|Schlagwortnormdatei}}'' or SWD), now part of GND

Wikidata content is used as fallback for the BNF, BPN, GND, ISNI, LCCN, MBA, NDL, NLA, ORCID, SUDOC, ULAN, and VIAF identifiers.

The template validates digits in many values (such as ISNI, ORCID, SUDOC, etc.<!--see module source-->) and shows an error if the check fails.

Wherever possible, the template also generates a link to [[WorldCat Identities]], using VIAF or LCCN values.

== Position ==
{{See also|Wikipedia:Manual of Style/Layout#Standard appendices and footers{{!}}Wikipedia:Manual of Style/Layout}}
As a metadata template, the Authority control template should be placed after the [[Wikipedia:External links|external links]] section and [[Wikipedia:Navigation templates|navigation templates]], right before the categories.

==Usage==
As a rule of thumb: (1) insert the empty version, (2) click "Show preview" to see which sources are automatically pulled from Wikidata, (3a) if you know more sources, add them in the template using their named param, (3b) alternatively, consider adding them to the article's "Wikidata item" (so that all versions of Wikipedia will automatically benefit).

== Error reports ==
{{Template error report}}

== Microformat ==
The template wraps each UID value with the [[HTML]] markup: <code><nowiki><span class="uid">...</span></nowiki></code>, which enables the first-found value to be included in an [[hCard]] [[microformat]]. For that reason, VIAF, where present, is emitted first.

== Tracking categories ==
This template may add the following categories:
* {{clc|Pages using authority control with parameters}} – articles and categories transcluding this template with explicit parameters (not loaded from WikiData)
* {{clc|VIAF not on Wikidata}}
* {{clc|VIAF different on Wikidata}}

Additional categories may be added by [[Module:Authority control]]:
* The module documentation contains a list, see {{section link|Module:Authority control|Tracking categories}}
* Specific identifiers are in subcategories of {{cl|Pages with authority control information}}
* Faulty parameters are in subcategories of {{cl|Wikipedia articles with faulty authority control information}}
