Template:Authority control/doc

Description
This metadata template links articles to various library catalogue systems (see ). 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 * 5) Outdated: Name Authority File (Personennamendatei or PND), now part of GND
 * 6) Outdated: Corporate Bodies Authority File (Gemeinsame Körperschaftsdatei or GKD), now part of GND
 * 7) Outdated: Subject Headings Authority File (Schlagwortnormdatei or SWD), now part of GND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.)
