Ahead of International Open Access Week and its 2026 theme, "The Cost of Knowledge," it is worth demystifying one of the most misunderstood parts of open publishing: the Article Processing Charge, or APC.
What an APC is — and is not
An APC is a fee, usually paid by the author, their institution, or their funder, that makes an article immediately free for everyone to read. It is not a payment for acceptance: a credible journal's editorial decision is independent of whether a fee is paid. APCs vary enormously between journals and publishers, so treat any single figure you hear as the exception, not the rule — and always check before you submit.
The equity problem
Charging authors to publish can simply move a barrier from readers to writers, and it falls hardest on researchers without grant funding or institutional support — often in lower-income countries. Taking "the cost of knowledge" seriously means taking that inequity seriously too.
Ways the cost can shrink or disappear
- Waivers and discounts. Many journals waive or reduce APCs for authors from eligible countries or in financial need. Look for the policy, and ask.
- Institutional and transformative agreements. Your library may have a deal that covers APCs for its researchers.
- Programmes like Research4Life that support access and publishing in eligible regions.
- Diamond open access — journals that charge authors nothing at all, funded by institutions, societies, or grants.
- Green open access — depositing an accepted version in a repository, which is free and widely permitted.
Open access should widen who can read and who can publish. We believe fees should be transparent and the available support easy to find — because knowledge that only the well-funded can share is not truly open.
