Open Access Loses Share – Market Sizing 2024 Sneak Peek - Delta Think

"Even though total OA output grew in 2023, it lost share as total output grew faster.

• OA has historically taken share. We estimate around 45% of paid-for scholarly articles were published OA in 2021, growing to just around 49% in 2022.
• In 2023, this fell back to around 48%.
• Although the decline in share is small, it’s significant. Normally OA gains share by a few percentage points per year. For the first time, preliminary data analysis results show it has lost share. This represents a reversal of long-term observations.
• We should note, however, that the underlying long-term trend is that of continuing growth in OA share. It is too soon to tell if the reversal is permanent, or whether it will pick up again.
• Last year we anticipated that OA would pass the 50% mark in 2023. This turned out not to be the case, so it does not yet account for the majority of monetizable output...."
