Template:Authority control/doc

See Authority control for more information.

Description
This metadata template links articles to various library (and other) 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.

Parameters
The following data sources are accepted:

Examples

Alexander Graham Bell:
