including an OCLC identifier that links to libraries in which the book can be found.14 This service, alongside similar services offered by Crossref for DOIs and using the PMID database, ensures that citation information provided in a Wikipedia article points readers to a deeper resource on the topic.

It is a language-independent, linked, open, structured database that is openly editable by both humans and computers. Since 2012 it has grown to include over 25 million items, each with a unique Wikidata identifier.
