The ISSN Portal and SUDOC are linked together

The open access version of the ISSN Portal now provides a URL link between each record in the ISSN Portal and the corresponding record in the French collective catalogue of the University Documentation System, Sudoc, if it includes location elements.

Sudoc lists all the documentary resources available in the 3,500 member libraries of its network, including nearly 600,000 records of localized continuing resources. Sudoc offers the cataloguers of its networks almost all the records of the ISSN Portal, through bi-monthly uploads of all records created or modified. In return, Sudoc contributes to the ISSN Portal through CIDEMIS application, which allows cataloguers to apply for ISSN assignments, or modifications of existing records, directly to the ISSN centres concerned.
