A total of 905,687 articles were published with the CC BY license in open access-only journals by members of OASPA during the period shown above, with 189,529 of those being published in 2016.
Interestingly, the data we have collected shows that, for OASPA members, the year-on-year growth remains steady for CC BY articles in fully open access peer-reviewed journals. From 2011 to 2012 the total growth was very high, jumping by around 50%. Comparing 2013 to 2012, growth had slowed to about 33%, but in the four years since then it has stabilised at an increase of roughly 14-15% per year.
Approximately 85% of the articles published by OASPA members as CC BY last year in OA journals can be attributed to just 6 publishers: Springer Nature (36%), PLOS (14%), MDPI (12%), Hindawi (10%), Frontiers (8%) and Copernicus (5%).
