"Supporting Open Access for 20 Years: Five Issues That Have Slowed the Transition to Full and Immediate OA"

Current estimates suggest that more than 50% of the world’s research articles are published open access and that there are around 20,000 fully OA journals. Data also indicates that publishing OA is, on average, cheaper than publishing in subscription journals. For example, an analysis by Delta Think shows that around 45% of all scholarly articles were published as paid-for open access in 2021, but this accounted for just under 15% of the total journal publishing revenue.

However, after two decades of discussions, advocacy, policy development and strategy, can this level of OA be considered a success, particularly when half of all research articles published today is hidden behind a paywall? I think not.
