In the Dark

Here’s an interesting bit of information that might surprise sceptics of Diamond Open Access publishing (as demonstrated by the Open Journal of Astrophysics). I found it Mastodon:

Interesting to see, that according to Openalex data, diamond open access is the most frequently used model among OA models recent papers were published under. From about 26,170,000 articles and reviews published between 2020 and 2025, over 8.7M are diamond OA, more than any other OA model. And even this is likely an underestimation, as OA type detection for diamond is DOAJ based, that many diamond journals have not registered with.

The results were obtained using the excellent OpenAlex catalog(ue). It shows that of the over 25 million articles published as Open Access in the years 2020-2025 (inclusive), over 8.6 million (around 35%) were Diamond Open Access publications, i.e. free to authors and readers alike (without APC). Far from being the fringe model that many people think, these figures demonstrate that Diamond Open Access is the most frequently used form of OA. I predict that its use will increase with time.
