Björk et al estimated for 2006, that between gold and green OA, 19.6% of
global yearly output of research could be accessed freely.
Can we devise a method of estimating/predicting the growth of the share of
OA in annual global research output, from the growth of gold OA journals and
OA mandates, both institutional and government?
