ROAD is now integrated into the ISSN portal. provides a free access to a subset of ISSN bibliographic records. These records describe the scholarly resources in open access that have been identified by the ISSN Network. ROAD is in line with the actions of UNESCO for promoting Open Access to scientific resources. ROAD is complementary to the Global Open Access Portal (GOAP) developed by UNESCO and providing a snapshot of the status of Open Access to scientific information around the world.

ISSN records are enriched by information extracted from indexing and abstracting databases, directories (DOAJ, Latindex, The Keepers registry) and journals indicators (Scopus). [See the list of Data Sources: https://portal.issn.org/node/91]


ISSN numbers are used as a matching key linking ISSN records with metadata related to their coverage by abstracting/indexing services or bibliometrics. External data give a quality insight on scholarly resources in ROAD, as the scholarly resources are indexed, evaluated and selected for their compliancy with some criteria set upon metrics, ethics and the preservation programs engaged.

Bibliometrics (impact factors) as well as indexing and abstracting services or external directories are mentioned on ISSN records if the case occurs.
