Statistics

These statistics provide an overview of the production of OA resources worldwide. They are computed through automatic searches against the ROAD database. They cover all the types of OA resources identified by an ISSN and, as such, listed in ROAD: academic repositories, conference proceedings, journals, monographic series and scholarly blogs.
 
The following statistics are available, other statistics may be added in the future if needed.
 
  • Number of resources per type, geographic area and country;
  • Evolution of the number of resources since 2004, per type, geographic area and country;
  • Number of resources per type and thematic area (applied sciences, technology; arts and humanities; information, media and libraries; medical sciences; pure sciences and mathematics; social sciences, economics and politics);
  • Coverage of the resources by indexing and abstracting services.
