This is a reminder that in February this year we tightened up procedures for article uploads. This includes checks that are carried out on uploads particularly ISSN, DOI, and full text URL information.
This means that, whether uploading article XML to us or JSON via the API, the metadata must include the exact same ISSN value(s) as those we hold in the journal record in DOAJ. If you have two ISSNs on the website and we only have one, you should contact us to have the second ISSN added. Usually, this is a quick process but sometimes you might need to contact ISSN.org to have them update their information before we can continue.
If you have any questions on this, do contact us.
