ROAD serves four major purposes :

  1. to provide a single access point to different types of online scholarly resources published worldwide and freely available,
  2. to provide information about the quality and prominence of OA resources, or at least the criteria they meet, by indicating by what services or journal indicators they are covered,
  3. as such, and once the coverage of ROAD is developed, to give an overview of the Open Access scholarly production worldwide (for statistics purposes for instance),
  4. to demonstrate new ways of using the ISSN for compiling information from various sources.
