OCLC control numbers
OCLC gives a special number (called "OCN" for "OCLC Control Number") to every new record in WorldCat. A record is metadata about books and things like books. Every record has a different number. There are more than a billion numbers, and there are more every day. Old numbers are small and new numbers are big.
OCNs help find books and things like books that do not have ISBNs. Many books from before 1970 do not have ISBNs. OCNs are often used for books in Wikipedia and Wikidata.
