International Standard Serial Number (ISSN)

The large growth in the number of serial titles world-wide and problems arising from changes in title, frequency, etc. led to the development of an international computer-based system for the identification and bibliographic control of serials/continuing resources. This is now known as the International Standard Serial Number (ISSN) Network.

Irish ISSN Centre

The Irish ISSN Centre at the National Library of Ireland is one of a network of over 80 national centres worldwide.  It is responsible for assigning ISSNs, free of charge, to serials published in the Republic of Ireland.  To date, over 4,000 Irish serials, active and defunct, have been assigned ISSNs. The Centre is also responsible for contributing Irish records to the world database of ISSN numbers, known as the ISSN Register, maintained by the ISSN International Centre in Paris.
