The ISSN (International Standard Serial Number) is the international code used to identify serial publications (journals, newspapers, gazettes, yearbooks, series of monographs, etc).

Spain has formed part of the ISSN Network since 1978, the year in which the Spanish ISSN Centre, currently part of the Biblioteca Nacional's Bibliographic Control Department, was created. The Spanish ISSN Centre, which is housed in the Biblioteca Nacional, is the only entity authorised to assign ISSNs to serial publications published in Spain.
