This study report assesses the free availability of scholarly publications during the 1996 to 2013 period. It is the largest scale measurement of open access availability performed to date: a sample of one-quarter of a million records was used to study the historical evolution of open access (OA) between 1996 and 2013 and a larger, one million records sample was used to perform an in-depth assessment of the proportion and scientific impact of OA between 2008 and 2013 in different types of OA, for different scientific fields of knowledge, and for 44 countries, the EU28, ERA, and the world.

Keywords: open access, bibliometrics, scientometrics, scientific production, scientific impact, publication statistics, Europe
