The definition
A diamond open access journal charges no fee to authors and no fee to readers. Its costs (editorial systems, hosting, identifiers, preservation) are met collectively, usually by institutions, libraries or public funders, rather than by whoever happens to be at either end of a given article.
The term is sometimes used loosely. A journal that waives fees for some authors is not diamond. Nor is one that is free to read but recovers costs through a subscription bundle elsewhere. The test is whether any individual is charged for participating.
How the models compare
| Model | Author pays | Reader pays | Who bears the cost |
|---|---|---|---|
| Subscription | No | Yes | Subscribing libraries and institutions |
| Gold OA (APC) | Yes | No | Authors, or their grants and institutions |
| Hybrid | Sometimes | Sometimes | Both, often for the same content |
| Green OA | No | No | Repositories are managed by individual institutions |
| Diamond | No | No | Institutions and public funders, collectively |
Why it matters for Ireland
Article processing charges of two to ten thousand euro fall hardest on researchers without grant funding, which in practice means early-career researchers, those in the humanities and social sciences, and anyone at an institution without a transformative agreement. In a small research system, that is a substantial share of the output.
There is also a stewardship argument. Journals covering Irish law, Irish economics, Irish history or Irish-language scholarship serve communities too small to be commercially attractive. Diamond publishing keeps them viable and keeps them here.
Bibliodiversity
A publishing system that only sustains what is commercially viable is a system that quietly narrows what can be studied. Diamond infrastructure is how small fields, minority languages and unusual formats stay in the record.
The policy landscape
Diamond open access has moved from the margins to explicit policy support over the last five years, in Ireland and across Europe.
- National. Ireland's National Action Plan for Open Research commits to open access to all publicly funded research, with explicit support for non-commercial routes.
- European. Council of the EU conclusions on scholarly publishing call for a not-for-profit, open scholarly communication ecosystem with no costs for authors or readers.
- Infrastructure. Coordinated European work to build shared standards and technical capacity across national nodes, of which Diamond Ireland is one.

Common objections
If nobody pays, the quality must be lower
Cost and quality are not linked in scholarly publishing the way they are in most markets. Peer review is donated labour under every model, including the most expensive. What money buys is production, distribution and profit margin, not rigour. Several diamond journals are the leading title in their field.
Diamond journals do not last
This is a fair concern and the reason infrastructure like this exists. Journals run on one person's goodwill do fail. Journals on shared, funded, professionally maintained infrastructure with preservation arrangements are considerably more durable than the alternative, and more durable than a commercial title that gets discontinued when it stops being profitable.
It will not count for promotion or assessment
What counts is indexing, citation and disciplinary reputation, none of which depend on the business model. A diamond journal indexed in DOAJ and Scopus counts exactly as much as a fee-charging one. Where local assessment practice says otherwise, that is a policy problem worth naming rather than a property of the model.
Someone still pays, you have just moved the cost
Correct, and we do not claim otherwise. The costs are real and are met by institutions and public funding. The argument is that collective funding of shared infrastructure is cheaper in aggregate and more equitable in distribution than charging individual researchers per article.
