GS1: the synergy of ISSN numbers and barcodes.

The SAIISA project was launched at the beginning of 2013. It involves semi-automatically assigning an ISSN to nearly 30,000 serial publications, of which approximately 10,000 are “dead” publications. SAIISA is led by 3 entities:
- the ISSN International Centre,
- the Italian ISSN National Centre (hosted by the Italian National Research Council), and
- the Italian union catalogue of serial publications (ACNP), hosted by the University of Bologna.


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.

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.
