Open access publishing has facilitated the rapid production and dissemination of scientific knowledge globally. Over the last three decades, it has built a reputation for producing high-quality peer-reviewed academic work.
This article provides an overview of the main aims of open access, including key features like accessibility, collaboration, and the open sharing of research materials. What is open access? How does open access publishing work?
Then, emerging trends in open access will be discussed, including the open science movement, the implementation of government mandates, and the use of AI in publishing.
The landscape of open access
Open access refers to the practice of making academic research as freely available to readers as possible. This includes being published online by an open access journal and being able to read, share, and use that work for free.
With the goal of making research universally available, proponents of open access are pushing for meaningful change within academia. This includes improved accessibility and collaboration within the publishing industry. OA enables scholars to share their research outputs much more quickly than closed access or subscription-based journals.
There are multiple types of OA publishing, based on a colour-coded naming system, including green, hybrid, and diamond. Each type offers a different form of kind of access to reading, sharing, and/or reusing academic work.
For example, gold OA is the standard option for many open access journals, as published articles are permanently and freely available upon publication. In addition, authors are able to keep the copyright to their work, and it can be shared and reused freely online.
OA has greatly benefited academia and global society more broadly. As research and publishing processes are opening up, more people are able to engage with and share academic work. This equals a broader readership and a public more knowledgeable and invested in scientific discovery.
Features of open access publishing
Open access publishing has helped to facilitate academic systems that are more open, accessible, and sustainable.
Accessibility and equity
The issue of accessible and equitable research and publishing processes is at the core of OA publishing. Increased financial and technological support for scholars who typically struggle to publish and/or access scientific research is needed. The divide between the global North and South has continued, even with the shift towards OA.
Democratization of knowledge
OA aims to increase accessibility to scientific research as much as possible. Reducing barriers so that readers from within academia and the public at large can facilitate the further democratization of knowledge.
By trying to equalize academic systems, marginalized and underrepresented communities from across the globe have the opportunity to participate in a more meaningful way.
Collaboration
Open access encourages partnerships between different stakeholders. Prioritizing collaboration among government bodies, public and private funders, academic institutions, and publishers.
In this sense, open access encourages researcher- and community-driven research. But authors, institutions, and publishers need more financial support to be able to realize the potential that this kind of work holds, including for policymaking and public education.
Emerging trends in open access
There are still some limitations to open access publishing within different scientific communities. But, overall, emerging trends in open access focus on alleviating the barriers that are a part of traditional publishing.
Open science
Open access publishing is an essential part of open science. This is an umbrella term that refers to an academic movement for increased accessibility and transparency within the whole scientific research process.
In addition to universal access to research publications, proponents of open science advocate for the entire research process to be as open and transparent as possible. This includes open data, which can be freely used, reused, and redistributed by anyone, with proper attribution.
Government mandates and transformative agreements
Open access is increasingly being required by public and private funders of scientific research under government mandates. Improving institutional support through transformative agreements strengthens the implementation of expanded forms of OA.
Government mandates and transformative agreements have pushed academic journals and book publishers to transition from closed or hybrid access to full open access status. Two important developments are Plan S, a coalition of European research and funding agencies, as well as the American government requiring research conducted with public funds to be published open access.
Using AI
In terms of technological developments, innovation is still top of mind, particularly when it comes to the use of AI. Popular tools like ChatGPT are being integrated into workflows by authors, reviewers, and publishers.
There is also an emerging interest in “machine-readable” science. This refers to organizing research and publications so that they can be more easily “read” and interpreted by AI.
The increased use of these kinds of tools presents both opportunities and challenges. While AI can assist with technical and organizational tasks, it cannot replace the expertise and skills of a human researcher.
Human expertise must be central, with AI a clearly defined support tool rather than an authority. Any use of AI should be done with careful thought to scientific ethical standards.
Continuing challenges
As more publications transition to OA, the publishing industry is faced with new opportunities and challenges.
As much as these trends in open access have made significant strides in addressing some of the key barriers to publishing and accessing scientific knowledge, inequalities and limitations do exist. In other words, open access is not a “silver bullet.”
The expansion of OA has been most successful for those institutions in the global North, which are already well represented across disciplines. Barriers for groups in the global South still exist, especially when it comes to financial challenges, such as the cost of APCs for authors. Scholars from, for example, South Africa, Brazil, and countries in the Middle East continue to champion their cause for equitable access to publish and reuse others’ work.
Today, in 2026, open access is becoming the rule, rather than the exception, for many institutions and publishers following OA mandates. Continuing trends in open access call for a sustainable, ethical publishing industry that supports the process and everyone involved.
