Open Access 2026: Should Scientific Publications Be Free? The Global Debate from Diamond OA to APCs

Should scientific knowledge be free for everyone, or does quality publishing carry a genuine cost? This question sits at the heart of the Open Access movement in 2026. Thousands of universities, funding bodies, and governments worldwide have made open access policies a mandatory standard — but the transition itself has created a new financial inequality.

What is Open Access?

Open Access (OA) is the principle that scientific articles should be freely and openly available to readers. Unlike the traditional subscription model, articles in OA journals are open to everyone from the moment of publication. Within this model, however, fundamentally different economic structures exist.

The difference between Gold, Green, and Diamond Open Access

In the "Gold OA" model, the journal charges nothing to readers but instead charges authors an Article Processing Charge (APC). "Green OA" means the author shares the article for free in an institutional repository. "Diamond OA" is entirely free for both readers and authors — funded by universities, scholarly societies, and public agencies.

What do the 2026 numbers say?

The rapid growth of Diamond Open Access

Researchers estimate that between 17,000 and 29,000 Diamond OA journals are currently active worldwide, publishing roughly 356,000 articles annually — about 8-9% of global scholarly output. Most of these journals operate on budgets under €10,000 a year and are sustained through the support of universities and scholarly societies.

The growing burden of APC fees

At the same time, the dominant form of "Gold OA" — the Article Processing Charge model — averages $2,600 and can exceed $10,000 at some prestigious journals. For researchers at under-resourced institutions and in the Global South, this effectively replaces one paywall with another.

UNESCO and the global equity initiative

Following the First Global Diamond OA Summit held in Toluca, Mexico in 2023, cOAlition S, ANR, Science Europe and other organizations put forward the idea of a global network for Diamond OA. UNESCO embraced the idea and is now leading a worldwide consultation on it. The Second Global Diamond OA Summit, to be held in Cape Town, will focus specifically on social justice in academic publishing.

What does this mean for Azerbaijani researchers?

1. Look for Diamond OA journals

If you cannot afford an APC, you can search the DOAJ (Directory of Open Access Journals) database for journals with Diamond OA status — these journals charge authors nothing at all.

2. Check payment terms in advance

Before submitting to any journal, find out its payment model (free, APC-based, or hybrid) — this is the single most important step to avoid unpleasant surprises.

3. Look into university and grant support

Some international funders and universities offer researchers partial or full financial support to cover APC payments.

4. Use transparent platforms

On AzPublish.az, every journal's payment status (free or paid) is shown clearly, so researchers can make an informed choice.

Conclusion

The Open Access movement was born to reduce inequality in access to scientific knowledge, but the APC model has, in effect, created a new financial barrier. The rapid growth of Diamond OA and UNESCO's global equity initiative suggest that 2026 may mark the beginning of fundamental change in this area.
