The free, public database behind Wikipedia. Each entry has a Q number and can hold referenced facts about a person or book, including a website and identifiers such as ISNI, VIAF, and Library of Congress numbers. Search engines and library systems may use those facts when they connect books to people. A Wikidata item isn't a Wikipedia article and doesn't guarantee a knowledge panel or ranking.
