Authority control is a method of creating and maintaining index terms for bibliographic material in a library catalogue.

It is commonly used where more than one person with the same name needs to be identified separately but it can be used for other subject material.

When used, authority control data links can be found near the bottom of Wikipedia pages.

WorldCat is a global cooperative union catalog which itemises the collections of 72,000 libraries in 170 countries and territories.
