ROAD, the ISSN Directory of Open Access Scholarly Resources, reached a milestone surpassing 22,000 resources. This was made possible thanks to the cooperation of the ISSN network.
Launched in December 2013 by the ISSN International Centre and supported by the Communication and Information Sector of UNESCO, ROAD provides a free access to a subset of the ISSN Register. This subset gathers bibliographic records describing and pointing to worldwide, multidisciplinary scholarly resources in open access that have been identified by the ISSN Network. ROAD gathers not only journals, but also conference proceedings, monographic series, academic repositories and blogs. ROAD innovative concept is that ISSN bibliographic records are enhanced with external information aggregated from data sources like indexing and abstracting services, metrics and registries.
