International Standard Name Identifier (ISNI)
The International Standard Name Identifier (ISNI) is an ISO standard (ISO 27729) that identifies public identities of parties. Essentially, this means the identities used publicly by individuals or organizations involved in creating, producing, managing and distributing content. The ISNI system uniquely and authoritatively identifies Public Identities across multiple fields of creative activity. ISNI provides a tool for disambiguating Public Identities that might otherwise be confused (such as Michele Smith the female singer, and Michele (Italian form of "Michael") Smith the male author).
The ISNI is not intended to provide direct access to comprehensive information about a Public Identity - instead, it's a tool that can provide links to other systems where such information is held.
An ISNI consists of 16 numerical digits. Example: ISNI 1422 4586 3573 0473
This basic ISNI lookup tool is provided by the Online Computer Library Center (OCLC).
