ISSN-L

11 April 2019

ISSN-L, the cluster identifier for periodical titles that aims to simplify management and discovery, is now available through the new public version of the ISSN portal.

Created in 1975, the ISSN is a unique and persistent identifier for journals and other serial publications. 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 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, offering users access to free ISSN identification metadata, which can also be reused in several linked open data formats, and to subscribers, it offers a new range of data and services through ISSN records enriched with information from external sources that cooperate with the ISSN International Centre.
