About ISSN

The International Centre for the registration of serial publications – CIEPSThe The purpose of the CIEPS – or ISSN International Centre, an intergovernmental organization – is to manage the International Serials Data System (ISDS), an automated registration system for serial publications in all disciplines.

The ISSN Network was formally established in 1975. The ISSN International Centre was officially created in Paris in 1976, under the terms of an agreement signed between UNESCO and France, the host country of the International Centre. This agreement consists in a law and decree which are regarded as a multilateral treaty for which UNESCO is the custodian of ISSN Network.

The ISSN Network is comprised of 88 member countries and regularly welcomes new members.
Its missions include:

  • assigning ISSNs,
  • maintaining a world database of serial publications,
  • serving as the standardisation authority in this area, and
  • distributing information concerning the ISSN and promoting its use.


The ISSN network and the ISSN International Centre based in Paris will celebrate its 40th anniversary in 2015. Throughout the year 2015, the ISSN network will organize events for libraries, publishers, users to share this occasion with us. Several actions will be undertaken. A blog will be specially created. It will publish historical documents provided by National Centres such as old and recent pictures of buildings, offices, colleagues, leaflets and brochures, archives, official letters, interviews and articles published by ISSN centres’ directors…

The ISSN Network will promote the 40th anniversary during different professional events such as 2015 IFLA conference in Cape Town, American Library Association (ALA), UKSG, Frankfurt Book Fair. A special issue of the journal Ciência da Informação will be published by the Instituto Brasileiro de Informação em Ciência e Tecnologia (IBICT) to mark this anniversary.
