ROAD, the Directory of Open Access scholarly Resources




 Send to a friend

ROAD is a service offered by the ISSN International Centre with the support of the Communication and Information Sector of UNESCO.

Launched in December 2013, ROAD provides a free access to those ISSN bibliographic records which describe scholarly resources in Open Access: journals, monographic series, conference proceedings, academic repositories and scholarly blogs. These records, created by the ISSN Network (90 National Centres worldwide + the International Centre), are enriched by information extracted from indexing and abstracting databases, directories (DOAJ, Latindex, The Keepers registry) and journals indicators (Scopus).

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.

Main features

• Faceted search
• Map search
Advanced search by country, subject, indexing service, journal indicator… and of course by ISSN
• Presentation of the data sources, whose data are used for enriching bibliographic records

Major purposes

• To provide a single access point to different types of online scholarly resources published worldwide and freely available.
• To provide information about the quality and prominence of OA resources, indicating by which services they are covered.
• To give an overview of the Open Access scholarly production worldwide (for statistics purposes for instance).
• To demonstrate new ways of using the ISSN for compiling information from various sources.

Next steps

1. To improve the geographical coverage and the coverage by types of resources.
2. To develop the coverage through retrospective identification of Open Access scholarly resources within the ISSN Register.
3. To develop thematic facets.
