France has played an important role in the European open access movement, particularly in the launch of the Berlin declaration.
Among French research structures, the research institutions (CNRS, INSERM in particular) played a major role at the beginning of the 2000’s, especially with the launch of the HAL open archive in 2001.
France has a national plan for the implementation of Open Science.
In addition to that, many initiatives have been taken nationally and at the institutional level to support OA:
23 French institutions have open access mandates requiring that authors self-archive their papers in their own institutional repository.
The ANR has issued an open access policy in November 2007, strongly encouraging the deposit of funded publications in open archives systems and in HAL in particular. It is worth noting that the Humanities and Social Sciences department has adopted a stronger policy mandating systematic deposit of publications in HAL-SHS.
