Template:Authority control/doc

Description
This metadata template links Wikipedia articles to various library catalogue systems (see authority control). At the moment, it is used almost exclusively in biographical articles.

The supported authority files include:
 * 1) Universal Authority File (Gemeinsame Normdatei or GND)
 * 2) Library of Congress Control Number (LCCN)
 * 3) Virtual International Authority File (VIAF)
 * 4) LIBRIS by the National Library of Sweden (SELIBR)
 * 5) Outdated: Name Authority File (Personennamendatei or PND), now part of GND
 * 6) Outdated: Corporate Bodies Authority File (Gemeinsame Körperschaftsdatei or GKD), now part of GND
 * 7) Outdated: Subject Headings Authority File (Schlagwortnormdatei or SWD), now part of GND

Where possible, the template also generates a link to WorldCat Identities, using the LCCN variable. (It will shortly be possible to link using VIAF values - this is being tested by OCLC and will be activated in the template as soon as it goes live.)
