A hybrid open access journal is a subscription journal — readers or their institutions pay to access most of its content — that also gives individual authors the option to make their own article freely available immediately, in exchange for paying an article processing charge (APC). The rest of the issue stays behind the paywall. This “opt-in, per-article” structure is what distinguishes hybrid from gold open access, where the whole journal is open, and from green open access, where the author self-archives a manuscript version separately rather than paying the publisher for open status.
Hybrid OA is the most commercially significant — and most contested — of the open access routes, because a single hybrid journal can generate subscription revenue from libraries and APC revenue from authors for the same underlying content. That overlap is the source of the “double dipping” criticism examined below, and it is why several major funders and library consortia now specifically exclude standalone hybrid APCs from what they will pay for.
How hybrid open access actually works
The mechanics are the same across most large subscription publishers:
- The journal itself is not indexed as open access — it retains a subscription/institutional-access paywall for the majority of its content.
- At acceptance, the corresponding author is offered a paid open-access option for that specific article, typically priced close to or the same as the publisher’s equivalent fully-OA journal APC.
- If the author pays, that one article is made freely readable on the publisher’s own site immediately, usually under a Creative Commons license (commonly CC BY), with no embargo.
- If the author does not pay, the article is published as a normal subscription article, readable only by subscribers or through green open access self-archiving after any publisher embargo.
Because the choice is made article-by-article, a single hybrid journal issue typically contains a mix of freely available and paywalled articles — which is the easiest way to visually recognize one.
Hybrid vs. gold, green, and diamond open access
Hybrid is one of four standard OA routes, distinguished mainly by who pays and where the free version lives. For a full side-by-side comparison across all four models — mechanism, typical embargo, license, and funder-compliance status — see Gold vs Green vs Diamond vs Hybrid Open Access. In short:
- Gold open access: the entire journal is open at the publisher’s site, usually funded by an APC.
- Green open access: no publisher fee; the author deposits a manuscript version in a repository, often after an embargo.
- Diamond open access: the entire journal is open with no fee to either reader or author, usually subsidized by a society, university, or consortium.
- Hybrid open access: a subscription journal with a per-article, author-pays opt-in to open status.
How to tell whether a journal is hybrid
A few practical checks:
- DOAJ listing. The Directory of Open Access Journals (DOAJ) only indexes fully open access journals — gold and diamond titles. A subscription journal that merely offers a paid OA option for individual articles is not eligible for DOAJ listing, so absence from DOAJ is a strong (though not the only) signal of hybrid status.
- The journal’s own author-fees or open-access page. Publishers are generally required by funder transparency policies to disclose hybrid status and APC pricing on the journal’s own site.
- Mixed access icons in the table of contents. Hybrid journal issues typically show a mix of open-access and locked/paywalled icons next to individual article titles — a fully gold or diamond journal will show every article as open.
The “double dipping” criticism
Hybrid open access is controversial primarily because of what the scholarly-communication community calls double dipping: a publisher can, in principle, be paid twice for the same content — once through the library’s ongoing subscription to the journal, and again through the individual author’s APC for that specific open article — without proportionally reducing the subscription price to reflect the OA revenue already collected. Library consortia and funders have pushed back on this in two main ways:
- Offsetting requirements. Some national consortia and Read & Publish deals require publishers to show that subscription prices are reduced (offset) in proportion to the hybrid OA revenue collected from that country’s or consortium’s authors.
- Funder exclusion of standalone hybrid APCs. A number of research funders will not directly pay a hybrid-journal APC unless it is covered under a pre-negotiated institutional or national Read & Publish / transformative agreement — see the funder-policy section below.
The practical effect is that hybrid open access is now usually accessed by authors through a bundled institutional deal rather than as an individual out-of-pocket APC payment, at institutions that have negotiated one.
Read & Publish and transformative agreements
Many large hybrid publishers now offer their open-access option to eligible authors at no direct cost through Read & Publish (R&P) or transformative agreements negotiated between the publisher and a university, library consortium, or national body. Under these deals, the institution’s existing subscription payment is restructured to also cover open-access publishing fees for its corresponding authors, up to some volume cap, with eligibility usually checked automatically by institutional email domain or affiliation at submission. This is the main route through which most authors at agreement-covered institutions now publish hybrid OA articles without paying an APC directly out of pocket or a grant budget.
Plan S, cOAlition S, and hybrid journals
Plan S, the open-access mandate coordinated by the funder coalition cOAlition S, does not recognize routine hybrid publishing as compliant on its own. cOAlition S instead recognized two narrow, time-limited bridges for hybrid content: Transformative Journals (individual hybrid journals committed to gradually converting to fully open access, tracked against year-on-year OA-share growth targets) and Transformative Agreements (the Read & Publish deals described above). cOAlition S ended its financial and eligibility support for the Transformative Journals route at the end of 2024, judging that model to have made insufficient progress toward full conversion; funder-covered publishing in a hybrid journal is now generally only compliant through an active transformative agreement, not simply by paying a hybrid APC directly. Because this area of policy moves on funder timelines, always check the current cOAlition S guidance (coalition-s.org) before treating a specific hybrid journal as compliant for a Plan S-funded project.
Funder and institutional policies on hybrid APCs
Policy on paying for hybrid open access varies significantly by funder and institution, and this is often the single most consequential thing for a researcher to check before submitting:
- Some funders and institutions will not reimburse a standalone hybrid-journal APC from grant funds at all, on the view that it duplicates subscription spending already committed institutionally.
- Others will pay a hybrid APC only when the journal is covered by an active transformative/Read & Publish agreement with the author’s institution.
- A smaller number of funders draw no distinction and will fund a compliant hybrid APC directly, provided licensing and embargo terms (typically CC BY, zero embargo) are met.
Because these rules differ by funder, by country, and by year, researchers should confirm current policy with their institution’s library or research office, and check the specific journal against any active transformative agreement, before assuming an APC will be covered.

Advantages and drawbacks for authors
Potential advantages:
- Access to a subscription journal’s existing readership, reputation, and Impact Factor while still meeting an open-access mandate for that specific article.
- Often the only OA route available in a field where the leading subscription journals have not launched fully-open competitors.
- No embargo and, typically, a CC BY license for the paid-OA version — comparable terms to gold OA.
Potential drawbacks:
- Not compliant with Plan S or similar mandates unless covered by a qualifying transformative agreement.
- Not indexed by DOAJ, which can reduce discoverability through OA-specific search and aggregation tools.
- Can be more expensive to fund out of pocket than a comparable fully-OA journal, and is the model most associated with the double-dipping critique above.
- Some library consortia and national policies (for example, several Nordic consortia have moved to stop signing new Read & Publish deals for hybrid journals from 2026 onward, directing funding toward fully open-access publishers instead) are actively reducing institutional support for the model, which may narrow no-cost access to hybrid OA over time.
Frequently asked questions
Is a hybrid open access journal the same as an open access journal?
No. An open access journal (gold or diamond) is open in its entirety. A hybrid journal is a subscription journal in which only the individual articles whose authors paid an APC are open; the rest of the content stays paywalled.
Does DOAJ list hybrid journals?
No. DOAJ (the Directory of Open Access Journals) restricts its index to fully open access journals. A hybrid journal’s individual open articles are not represented in DOAJ simply because the underlying journal offers a hybrid option.
Will my funder pay a hybrid journal’s APC?
It depends on the funder and, often, on whether your institution has a transformative/Read & Publish agreement with that specific publisher. Many funders that follow Plan S-style principles will not pay a standalone hybrid APC outside such an agreement. Check current policy directly with your funder and your institution’s library before submitting.
What is “double dipping” in the context of hybrid OA?
It refers to a publisher collecting both subscription revenue from libraries and per-article APC revenue from authors for the same journal, without a corresponding reduction in subscription price. Offsetting clauses in some national and consortial deals exist specifically to address this.
Are hybrid open access articles the version of record?
Yes. Unlike green open access, where the freely available copy is usually an author-accepted manuscript, a hybrid OA article is normally the publisher’s fully typeset version of record, made open immediately with no embargo.
