DOAJ records now link to the corresponding ISSN entries in the ISSN Portal
DOAJ and the ISSN International Centre have enjoyed a fruitful partnership for several years. The ISSN is a requirement for journals applying to DOAJ (you have to have one to apply). ISSN IC and DOAJ are delighted to announce that DOAJ records now link back to the corresponding ISSN entries in the ISSN Portal.
