ISSN IC and Spanish National ISSN Centre share a common project of retrospective ISSN assignment
The ISSN International Centre and the Spanish ISSN National Centre have recently completed a common project of semi-automated retrospective assignment of ISSN to bibliographic records from the Spanish Serials Union Catalogue (Catálogo Colectivo de Publicaciones Periódicas), which is managed at the National Library of Spain (Biblioteca Nacional de España). As a result, more than 10,737 ISSN records were added to the ISSN Register.
