In 2007, ISO 3297 introduced the mechanism of “Linking ISSN” (ISSN-L) for the purpose of supporting search and delivery functionality across all media versions.  The ISSN-L simplifies the search, recovery and delivery of data across services including, in particular, search systems and knowledge databases. The ISSN International Centre publishes an ISSN/ISSN-L matching table, updated daily and available on the ISSN International Centre’s website upon request.

Since January 2018, the “cluster” ISSN-L record type is also available through the new public version of the ISSN Portal (https://portal.issn.org) which contains more than 2,5 million ISSN records. The Portal offers users access to free ISSN essential identification metadata, which can also be reused in several linked open data formats; for subscribers, it offers a completely new range of data and services through ISSN records enriched with information from external sources that cooperate with the ISSN International Centre.
