Institutions and repositories from different domains, including many of ISNI's Registration Agencies and Members, contribute their data to the central ISNI database and work directly with the ISNI Assignment Agency. ISNI records are enriched thanks to these contributions, which frequently disclose cross-domain links between libraries authority files, rights management societies, researchers’ databases, music industry, book supply chain and more.
The list below shows current and past direct data contributors, as well as their main areas of interest or specialization. The codes given in square brackets identify the sources of information in the database.
