ISNI (ISO 27729) is the certified global standard number for identifying contributors to creative works and those active in their distribution. The ISSN International Centre is a member of ISNI International Agency and as such, makes use of existing ISNI to complete ISSN records with identifiers assigned to issuing bodies for example. This practice is also extending to ISSN National Centres thus providing interoperability between ISSN and ISNI.
Latindex represents a major initiative launched by the National Autonomous University of Mexico (UNAM) in 1997 to promote the visibility and dissemination of Ibero-American scientific journals, and improve the quality of journals published in the region. Latindex and the ISSN International Centre signed a Memorandum of Understanding in September 2015. The purpose of this three-year agreement is to promote both parties and exchange metadata about serials.
The Keepers Registry is an online service promoting the long-term preservation of e-journals by memory agencies across the globe which act as Keepers. The registry states which e-journals are kept safe by one or more Keepers and also mentions those which are still at risk of loss. This innovative service is developed by EDINA (University of Edinburgh) in partnership with the ISSN International Centre.
