On January 4th, 2018, the ISSN international Centre launched its new Portal and its new Extranet which are available at

The ISSN Portal has been enriched with new features such as improved search functions (faceted search, cartographic search), multiple display options, additional data, i.e. a unified subject classification based on UDC, and the possibility to download bibliographic information in MARC and linked data formats.

The Customer Extranet allows each subscribing entity to have its own access point with details about its subscription. Specific statistics are available to help with usage monitoring. The new Extranet therefore allows customers of the ISSN Portal greater autonomy in managing their accounts.
