Gold and Hybrid Open Access Follow Upward Trajectories | Open Science

"Paradoxically, though the 2017 levels of Open Access article output have markedly declined across geographic regions and academic fields, the underlying trends tentatively point to the growing or stable levels of Gold Open Access over the last decade with rising levels of hybrid Open Access in recent years, based on university-level data from the Netherlands. A recent report indicates possible reasons for these developments.

In their preprint article published on January 11, 2018, Jeroen Bosman and Bianca Kramer have presented the results of their qualitative inquiry into the yearly levels of Open Access based on Web of Science and oaDOI data around the world. While their findings are fairly consistent across scholarly disciplines and national contexts, which show a decline in the overall Open Access levels from approximately 26% of article output worldwide in 2016 to close to 18% in 2017, despite a consistent growth trend in this indicator levels which rose from barely above 20% in 2010 to slightly above 25% in 2015.

Among the possible explanations for these findings Bosman and Kramer cite the built-in access lag that free content not licensed as Creative Commons from the outset, which is also referred to as bronze Open Access, entails. In other words, since bronze Open Access terms are usually applied after 1 or 2 years from the date on which original articles are published, in 2017 statistics these prospective free access articles are likely to be listed as closed-access publications some of which, which may be as high as 40%, can be expected to switch to bronze Open Access retroactively. This is also likely to apply to Green Open Access articles that remain in subscription-based, and effectively closed, access for set embargo periods which can vary between 6 and 24 months. These conditionalities may thus affect the manner in which portals, such as Web of Science, index article output, while introducing a bias in latest year figures...."
