International Identifier for serials
and other continuing resources, in the electronic and print world

GS1: the synergy of ISSN numbers and barcodes.

GS1 is an international organisation which defines the specifications for barcodes, among other things. The agreement established between GS1 and the ISSN International Centre allows ISSN numbers to be used in barcodes according to the EAN13 specifications, with the prefix 977 reserved for serial publications.


The ISSN International Centre and its network take part in Think.Check.Submit, a new campaign led by representatives from ALPSP, DOAJ, INASP, LIBER, OASPA, STM and individual publishers. This campaign will help researchers understand their options, and key criteria they should check before submitting their papers for publication. Further information available at .


DOAJ and the ISSN International Centre signed a Memorandum of Understanding in December 2015. The purpose of this agreement is to promote both parties and exchange metadata about quality, open access journals in the framework of ROAD service. The benefit of this working agreement is to give an insight about trusted peer-reviewed open access journals. Being indexed in the DOAJ means that the journals considered adhere to high levels of quality regarding best practices.


The ISSN International Centre and ProQuest work together to improve electronic loading of serial titles worldwide. Further information available at
