This template is used on 21,50,000+ pages, or roughly 395% of all 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 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.
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.) 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
As a metadata template, the Authority control template should be placed after the external links section and 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).
ISNI is a method for uniquely identifying the public identities of contributors to media content such as books, TV programmes, and newspaper articles. Please take care not to confuse ISNI and ORCID identifiers.
Authority data on researchers, academics, etc. The ID range is a subset of the ISNI range. For free text links (for example when mentioning a person on page which is not about them), it is also possible to use {{ORCID}}. Authors—including Wikipedia editors—may obtain an ORCID by signing up at orcid.org/register. Please take care not to confuse ORCID and ISNI identifiers.

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 hCardmicroformat. For that reason, VIAF, where present, is emitted first.
