Data for the above chart is available for download: OASPA Members CC-BY Growth_Data to 2013
A total of 399,854 articles were published with the CC-BY license by members of OASPA during the period shown above, with 120,972 of those being published in 2013 alone. These numbers only include articles that were published in journals whose entire content is Open Access, so articles that were published in hybrid OA journals are not included.
OASPA members were invited to share their data to update the previous post on this topic.
Figures for fully open access titles were supplied by the following members of OASPA as number of CC-BY articles published per year since implementation of the license by that publisher:
BioMed Central (2000-2013) SpringerOpen (2011-2013), Hindawi (2006-2013), PLOS (2003-2013), Frontiers (2012-2013), Leibniz-Institute for Psychology Information/ZPID (2012-2013), American Institue of Physics (2011-2013), MDPI (2008-2013), ecancermedicalscience (2007-2013), AOSIS (2012-2013), eLife (2012-2013), SSPP (2005-2013), PeerJ (2013 only), Ubiquity Press (2011-2013), Copernicus (2007-2013), JMIR Publications (2000-2013), OUP (2013 only) and Igitur (2009-2013).
This chart will be updated again in the future as more data is collected.

It would be interesting (aka more informative and useful to debate) to see these data/this figure in relation to the number of papers published in total – whatever business model they were published under/within/upon. I think it’s a million papers a year nowadays in total, so while there is exponential growth here, is it not, perhaps, akin to a population of microbes on an elephant? An irritant, but of no great interest to the great unwashed that are sci authors? That said, I hear microbial causes of death in elephants are increasing and extinction looms for the great beasts…
