ISNI

The International Standard Name Identifier (ISNI) is a 16-character alphanumeric identifier designed to uniquely identify the public identities of contributors to creative works and those active in public life. It aims to disambiguate personal names and corporate bodies across libraries, archives, publishing, motion picture, music, research, broadcasting, and rights management sectors. The standard supports interoperability among metadata systems used by organizations such as British Library, Library of Congress, Bibliothèque nationale de France, OCLC, and ProQuest.

Background and Purpose

ISNI was developed to address name ambiguity problems encountered by institutions like National Library of Australia and Deutsche Nationalbibliothek when cataloguing materials related to figures such as William Shakespeare, Wolfgang Amadeus Mozart, Pablo Picasso, Agatha Christie, and Haruki Murakami. The initiative followed earlier identifier projects exemplified by International Standard Book Number, Digital Object Identifier, and Virtual International Authority File. ISNI facilitates clear attribution for creators involved with entities such as Universal Music Group, Warner Bros., BBC, The New York Times Company, and National Geographic Society, and assists rights organizations like ASCAP and PRS for Music in tracking works linked to individuals like Bob Dylan, Adele, Quentin Tarantino, Hayao Miyazaki, and J. K. Rowling.

Structure and Identifier Format

An ISNI consists of 16 digits presented in four groups of four, with the final digit serving as a check character calculated using the ISO 7064 MOD 11-2 algorithm similar to checks used by International Standard Book Number systems. The format allows representation of entities ranging from solo creators such as Ludwig van Beethoven and Virginia Woolf to corporate bodies like Sony Corporation, Penguin Random House, and The Walt Disney Company. ISNI entries record authorized and variant forms of names reflecting languages and scripts used by institutions such as Biblioteca Nacional de España, National Diet Library (Japan), and China National Publications Import & Export (Group) Corporation.

Allocation and Registration Process

Allocation of an ISNI is performed through registration agencies and registration agencies coordinate with data contributors including archival services at Smithsonian Institution, rights databases from Society of Authors (UK), and bibliographic hubs like Europeana. Applicants—individuals or organizations—may apply via agencies such as ProQuest or through aggregators like OCLC which reconcile duplicate candidate records with authorities including VIAF and national bibliographies from Library and Archives Canada. The process incorporates identity evidence drawn from publications, recordings, broadcasts, and databases held by institutions such as British Museum, New York Public Library, Harvard University Library, UCLA Library, and Getty Research Institute. Where conflicts exist, registrars consult records maintained by International Federation of Library Associations and Institutions members and legal identifiers held by corporations like Thomson Reuters.

Governance and Administration

ISNI is governed by an international agency composed of founding bodies including British Library, CISTI, EDItEUR, and VIAF partners, overseen by a board that includes representatives from IFLA, WIPO, and participating copyright agencies such as CISAC. Administrative operations are carried out by a central registration agency headquartered in London that liaises with national libraries like National Library of Scotland and commercial partners like ORCID and Crossref. Policy-making consults stakeholders spanning academic publishers like Elsevier and Springer Nature, collecting societies including BMI and SACEM, and cultural institutions such as Museum of Modern Art.

Adoption and Use Cases

ISNI has been adopted by libraries, publishers, rights management organizations, archives, and media companies to improve discovery, rights clearance, and metadata reconciliation. Libraries such as New York Public Library use ISNI to link authority files for figures like Mark Twain, Emily Dickinson, and T. S. Eliot; music databases at Universal Music Group and Sony Music Entertainment use ISNI to disambiguate performers including Freddie Mercury and Madonna (entertainer). Film and television credits at Netflix and HBO benefit from ISNI integration for contributors like Alfred Hitchcock, Kathryn Bigelow, and Spike Lee. Scholarly publishers including Taylor & Francis and Wiley-Blackwell map ISNI to researcher identifiers for authors such as Noam Chomsky and Amartya Sen to streamline citation and attribution workflows. Cultural heritage aggregators like Europeana and Digital Public Library of America use ISNI to consolidate records for collections spanning creators from Frida Kahlo to Ansel Adams.

Relationship to Other Identifier Systems

ISNI interoperates with systems including ORCID for researcher identification, VIAF for library authority aggregation, DOI for persistent object identification, Getty AAT for art terminology, and MusicBrainz for community-maintained music metadata. Crosswalks connect ISNI to national authority files such as those maintained by Bibliothèque nationale de France, Deutsche Nationalbibliothek, National Diet Library (Japan), and Library of Congress authorities, and to rights databases run by CISAC affiliates. Integration with commercial identifier systems like Wikidata and IMDb enhances discoverability for creators appearing in databases covering figures from Leonardo da Vinci to Stan Lee.
