Overview

The International Standard Name Identifier (ISNI) is a persistent, machine-readable identifier consisting of 16 digits used to distinguish public identities connected with creative and intellectual works. ISNIs are assigned to people and organizations associated with books, music, film, journalism, visual arts and other forms of authorship and contribution. The system is maintained by the ISNI Agency and is part of the family of standards overseen by the International Organization for Standardization.

Structure and scope

An ISNI takes the form of a 16-digit numerical code and includes a mechanism for validating the number so that transcription errors can be detected. It is intended to provide a single reference for an identity across libraries, publishers, rights organizations, aggregators and digital services. ISNIs cover natural persons (authors, composers, performers, journalists) and legal entities (publishers, record labels, production companies).

History and governance

The ISNI framework was developed to address long-standing problems of name ambiguity in bibliographic and rights management systems. The database project gained formal momentum around 2011 under the ISNI Agency, which coordinates the assignment and aggregation of records. ISNI is implemented as an ISO standard and is stewarded through collaboration among libraries, publishers, rights organizations and technology providers.

Uses and examples

ISNIs are used to improve discovery, disambiguation and data exchange. Typical applications include:

  • Library and cataloging systems that need to distinguish authors with similar names;
  • Publishers and aggregators linking works to contributors;
  • Rights and licensing workflows that require unambiguous identification of creators;
  • Metadata enrichment across platforms to connect records originating in different databases.
Many institutions and services consult the central ISNI database or exchange ISNI values as part of their metadata feeds.

Assignment, sources and data quality

ISNI records are created by combining contributions from national libraries, bibliographic agencies, rights bodies and commercial partners. The process typically uses automated clustering to match name-bearing records, followed by human review where ambiguity remains. The Agency publishes public records and reports growth in the register as more data sources are integrated; the combined dataset runs to millions of identities.

Distinctions and notable facts

ISNI identifies identities rather than works or publications; it is therefore complementary to other identifiers such as ISBN (books), DOI (digital objects) and ORCID (researcher-focused IDs). ISNI is not itself proof of legal ownership or rights, but it is widely used as a practical tool for linking and disambiguation across the information and creative industries.

Questions and answers

Q: What is the International Standard Name Identifier?

A: The International Standard Name Identifier, or ISNI, is a 16-digit number used to uniquely identify individuals who have contributed to creative works such as books, newspapers, music, plays, movies and television programs.

Q: Who runs the database of ISNI numbers?

A: The ISNI Agency runs the database of ISNI numbers.

Q: What organization is the ISNI Agency a part of?
