Bowker rejoined the ISNI International Agency in January 2025 and subsequently launched an online portal for assigning identifiers. The service aims to improve name disambiguation in the creative supply chain.
Why it matters
The service addresses rising challenges in search and discovery by distinguishing human creators from AI-generated content. Standardizing these identities helps businesses ensure accuracy in metadata across global distribution channels.
The ISNI database contains 16.6 million total records, including 14.5 million for individuals and 2 million for organizations or groups. This global standard supports unique identification for contributors across the book industry and creative sectors.
The players
Bowker
A bibliographical information provider that manages metadata and identification services for the publishing industry.
ISNI International Agency
A global standards body that maintains a public database of identifiers for contributors to creative works.
The details
The new portal at ISNI.Bowker.com enables users to assign identifiers to creative entities directly. By automating this process, the service aims to reduce name ambiguity for retailers and distributors. It provides a technical mechanism for publishers to clearly mark human contributions in an environment increasingly affected by AI-generated output.

Market Landscape
This development follows the established adoption pattern of the ISNI global metadata standard to improve data interoperability. It marks a strategic move to centralize identity verification as the industry manages a surge in AI-generated creative output.
Publishers should evaluate whether their current metadata workflows require unique ISNI identifiers to improve search discoverability. Operators should monitor how these identity standards influence their data presence on third-party retail platforms.
The takeaway
Standardizing contributor identity is critical for maintaining metadata integrity as content volume grows. Publishers should verify their catalog against the 16.6 million records currently active in the ISNI database to ensure author and organization attribution accuracy.
