key title

n. A uniform title assigned to periodicals and linked to a specific International Standard Serial Number (ISSN) that combines a publication's title with any necessary qualifiers to distinguish it from other publications with the same title.


ISSN 2004 If the title of the publication changes in any significant way, a new ISSN must be assigned in order to correspond to this new form of title and avoid any confusion. A serial publication whose title is modified several times in the course of its existence will be assigned each time a new ISSN, thus allowing precise identification of each form of the title: in fact it is then considered that they are different publications even if there is a logical link between them.
