TL;DR — Quick Answer
Open access publishing makes research papers freely available to read online, without subscription or payment barriers. There are two main types: Gold open access, where the article is freely available immediately on the journal’s website (often funded by an author fee called an APC), and Green open access, where the author deposits a version of the paper in a free repository. Open access increases the reach, visibility, and citation of research. The main consideration for authors is the article processing charge, which can be substantial — though many journals offer waivers and many funders cover the cost.
For most of the history of academic publishing, research was locked behind paywalls. To read a research paper, you — or more often your institution’s library — had to pay for a subscription to the journal that published it. This system meant that research funded by public money, conducted at public institutions, was often inaccessible to the very public that funded it, and to researchers at institutions that could not afford expensive subscriptions.
Open access publishing emerged to change this. By making research freely available to anyone with an internet connection, open access has transformed how research is shared, accessed, and built upon. For researchers deciding where and how to publish, understanding open access — its types, its benefits, and its costs — has become essential.
This guide explains what open access publishing is, the different types, its advantages and considerations, and how to navigate it as an author.
What Is Open Access Publishing?
Open access publishing makes research outputs — primarily journal articles — freely available online, without the subscription fees or paywalls that traditionally restricted access. Anyone, anywhere, can read open access research without payment.
The principle behind open access is that research, particularly publicly funded research, should be freely available to all who can benefit from it — other researchers, practitioners, policymakers, students, and the public. Removing access barriers increases the reach and impact of research and accelerates the advancement of knowledge.
Open access does not mean research is unreviewed or of lower quality. Reputable open access journals conduct the same rigorous peer review as subscription journals. The difference is in how access is funded and provided — not in the quality of the research or the review process.
The Two Main Types of Open Access
Gold Open Access
In gold open access, the final published version of an article is freely available immediately on the journal’s website. Anyone can access, read, and download it from the moment of publication.
Gold open access is typically funded through an Article Processing Charge (APC) — a fee paid by the author, their institution, or their funder to cover the costs of publication. Because the reader does not pay, the cost shifts to the author side. APCs vary widely, from modest amounts to very substantial sums for prestigious journals.
Many fully open access journals operate on this model. Some traditional subscription journals also offer a gold open access option for individual articles — called hybrid open access — where authors can pay an APC to make their specific article open access while the rest of the journal remains behind a paywall.
Green Open Access
In green open access, the author deposits a version of their paper — often the accepted manuscript before final typesetting — in a freely accessible repository. This might be an institutional repository, a subject repository, or a preprint server. The paper is freely available through the repository, even if the final published version remains behind a paywall on the journal’s website.
Green open access usually involves no fee to the author. It relies instead on self-archiving — the author depositing their work in a repository. Many journals permit green open access archiving, sometimes after an embargo period during which the paper remains exclusive to the journal.
Comparing the Types
| Feature | Gold Open Access | Green Open Access |
|---|---|---|
| What is free | Final published version | Author’s manuscript version |
| Where it is hosted | Journal website | Repository or preprint server |
| Cost to author | APC (often substantial) | Usually free |
| Availability | Immediate | Sometimes after embargo |
| Version quality | Final, typeset | Pre-typeset manuscript |
The Benefits of Open Access Publishing
Wider reach. Open access research can be read by anyone, anywhere — not just those at institutions with expensive subscriptions. This dramatically expands the potential audience for your work, including researchers in developing countries, practitioners, and the public.
Increased citations. Research consistently suggests that open access articles tend to be cited more than paywalled articles, likely because they are more easily accessible to more potential citing authors. Greater visibility translates into greater impact.
Faster dissemination. Open access, particularly through preprint servers, allows research to be shared quickly, accelerating the pace at which knowledge spreads and builds.
Public benefit. Open access makes publicly funded research available to the public that funded it, to policymakers who can apply it, and to practitioners who can use it — increasing the real-world impact of research.
Compliance with funder mandates. Many research funders now require that the research they fund be made openly available. Open access publishing satisfies these mandates.
The Considerations and Challenges
Article Processing Charges. The main consideration for gold open access is cost. APCs can be substantial, and not all researchers or institutions can afford them. This creates a different kind of barrier — shifting from a barrier to reading to a potential barrier to publishing.
Predatory open access journals. The APC model has been exploited by predatory journals that charge fees while providing no genuine peer review. The open access label alone does not guarantee legitimacy — authors must still verify that an open access journal is reputable and conducts genuine peer review.
Navigating funding. Many funders and institutions provide funds to cover APCs, and many journals offer waivers or discounts for authors from lower-income countries or without funding. Navigating these options requires effort but can make open access publishing affordable.
Quality variation. As with all publishing, open access journals vary in quality. The best are highly prestigious and rigorous; others are weak or predatory. The reputation and indexing of the specific journal matter more than whether it is open access.
How to Publish Open Access Affordably
Open access does not have to be expensive. Several routes make it accessible.
Use green open access. Depositing your manuscript in a repository is usually free and makes your work openly available without paying an APC. Check your journal’s self-archiving policy and your institution’s repository.
Seek APC waivers. Many reputable open access journals offer full or partial APC waivers for authors from lower-income countries or without research funding. Check the journal’s waiver policy before assuming you cannot afford to publish.
Use funder and institutional support. Many research funders cover APCs as part of grants, and many institutions have funds specifically for open access publishing. Investigate what support is available to you.
Choose diamond open access journals. Some open access journals — called diamond or platinum open access — charge neither readers nor authors, being funded by institutions or organisations. These provide open access with no APC at all.
As Dr. Madhuri Kanojiya, Founder of Empire Research Press, advises: “Open access has genuinely democratised research — but authors must navigate it wisely. The goal is to make your work freely available through a legitimate, reputable channel, not to pay a fee to a predatory journal that calls itself open access. Verify the journal’s legitimacy first, then explore the many routes — green archiving, waivers, funder support — that can make open access affordable.”
Open Access and Predatory Journals — A Caution
It is important not to confuse open access with predatory publishing. Open access is a legitimate, valuable publishing model. Predatory journals are illegitimate publications that exploit the APC model — but they are not what open access means.
Many of the world’s most prestigious and rigorous journals are open access. The open access label says nothing about quality — what matters is whether the specific journal is reputable, indexed in recognised databases, and conducts genuine peer review. Verify these for any journal, open access or subscription, before submitting.
Conclusion
Open access publishing has transformed how research is shared, making knowledge freely available to anyone who can benefit from it. Through gold open access, research is free to read immediately on the journal’s website; through green open access, authors make their work available through repositories.
For authors, open access offers wider reach, more citations, and greater impact — though the APC costs of gold open access require navigation. With green archiving, waivers, and funder support, open access is more affordable than it first appears. The essential discipline is to verify the legitimacy of any journal before submitting, ensuring your work appears in a reputable, genuinely peer-reviewed publication that happens to be open access — not in a predatory journal exploiting the model.
Frequently Asked Questions
Q: What is open access publishing?
Open access publishing makes research papers freely available to read online, without subscription fees or paywalls. Anyone, anywhere, can access open access research without payment. The principle is that research — particularly publicly funded research — should be freely available to all who can benefit from it. Open access does not mean lower quality: reputable open access journals conduct the same rigorous peer review as subscription journals. The difference is in how access is funded and provided, not in the quality of the research.
Q: What is the difference between gold and green open access?
In gold open access, the final published version of an article is freely available immediately on the journal’s website, typically funded by an Article Processing Charge (APC) paid by the author, institution, or funder. In green open access, the author deposits a version of their paper — usually the accepted manuscript — in a free repository, making it openly available even if the final published version remains behind a paywall. Green open access is usually free to the author, while gold often requires paying an APC.
Q: What is an Article Processing Charge (APC)?
An Article Processing Charge (APC) is a fee paid to make an article open access under the gold open access model. Because readers do not pay to access the article, the cost shifts to the author side — the APC covers the journal’s publishing costs. APCs vary widely, from modest amounts to very substantial sums for prestigious journals. The author, their institution, or their research funder may pay the APC. Many journals offer waivers or discounts for authors from lower-income countries or without research funding.
Q: Does open access publishing increase citations?
Research consistently suggests that open access articles tend to be cited more than paywalled articles. This is likely because open access articles are more easily accessible to more potential citing authors — researchers who cannot access paywalled content can read, use, and cite open access work freely. Greater accessibility translates into greater visibility and impact. While the size of the citation advantage varies across studies and fields, the general finding that open access increases reach and citation is well-supported, making it attractive to authors seeking to maximise their research impact.
Q: Is open access the same as predatory publishing?
No — open access and predatory publishing are entirely different. Open access is a legitimate, valuable publishing model used by many of the world’s most prestigious and rigorous journals. Predatory journals are illegitimate publications that exploit the APC model — charging fees while providing no genuine peer review. The open access label says nothing about quality; what matters is whether the specific journal is reputable, indexed in recognised databases, and conducts genuine peer review. Always verify a journal’s legitimacy before submitting, whether it is open access or subscription-based.
