News & Views: Open Access Mandates and Open Access Adoption

Dan Pollock and Ann Michael • February 8, 2021

As more funders implement or consider mandates, we were curious whether the data show any connection between funders’ open access policies and open access uptake.


Introduction


The Registry of Open Access Repository Mandates and Policies (ROARMAP) is a searchable international registry charting the growth of open access mandates and policies adopted by universities, research institutions, and research funders. It tracks the policies requiring or requesting researchers to provide open access to their peer-reviewed research article output. It focuses on policies about use of repositories, but also captures information about OA publishing.


By comparing the number of policies in ROARMAP with proportion of output that is open access, we can see whether a relationship exists between policy activity and OA uptake. We define OA to include articles that are both free to read and reuse, in all journal types. We exclude public access (“bronze”). As we want to examine market activity, we also exclude repository-only versions of articles.


Policies and Uptake


Figure 1, below, shows how numbers of policies and the proportion of output that is open access track over time. The blue bars show the cumulative number of policies (left axis). The orange line shows the proportion of articles that are OA (right axis).

Sources: ROARMAP, Crossref, Unpaywall, Delta Think Analysis.


Clearly both are growing and there is a strong correlation overall. However, the two sets of numbers follow slightly different trajectories:

  • The numbers of policies appear to follow a classic S-shaped curve. A burst of steep growth from around 2009 to 2018 is flattening off. For example, in 2013 and 2014 growth was around 20% per year. Last year it was 1%.
  • The proportion of OA articles appear to follow more of a shallow hockey stick. Its initial growth curve has given way to a straighter line.


Although both curves are broadly similar, it seems that they diverge in the detail. The number of OA policies grew faster than OA uptake around 2001 to 2017. But we have since seen a turnaround. The proportion of OA continues to increase apace, even though the numbers of policies have almost reached a steady state.


Growth can be hard to judge from absolute numbers. For example, the straight line above actually points to slowing growth. (Constant growth compounds and would show as an exponential curve.) Figure 2 below compares the annual changes in both measures.

This month we look at our latest data about Article Processing Charges (APCs). Per article pricing is a fundamental building block for all paid publishing models, so our review provides an invaluable insight into how costs of open access continue to evolve. APC prices in general continue to increase, but at a slower rate compared with this time last year. Important nuances in the distribution of prices continue to affect the value and cost of paid publishing models. Background Each year we survey the list Article Processing Charges (APCs) of a sample of major and significant publishers. Covering more than 20,000 titles going back to 2016, our dataset represents one of the most comprehensive reviews of open access pricing. To compare like for like, we consistently analyze non-discounted, CC BY charges. We take a snapshot at the end of every January, so we can track yearly changes while controlling for the different times of year that publishers may update prices. Our statistics exclude zero or unspecified APCs, although these are included in our underlying data. This allows us to understand trends where publishers choose to charge APCs without skewing averages. We run separate analyses around APC-free models. Headline Changes Going into 2025, we have seen APC pricing increasing but falling back to long-term trends. Fully OA APC list prices across our sample have risen by around 6.5% compared with 9.5% this time last year. Hybrid APC list prices have risen by an average of 3% compared with 4.2% this time last year. Maximum APCs for fully OA journals remain at $8,900. Maximum APCs for hybrid journals now top out at $12,690 (up $400 from last year). Big jumps in prices happened last year, driven by high inflation. In 2020-2021 prices were driven up when high-impact journals began offering OA options for the first time. In both cases, increases subsequently fell back to averages. Underlying trends continue. There are around 2.6x more hybrid journals than fully OA ones, down from 2.9x a year ago. Hybrid journals follow (or, rather, set) a similar pattern to the market overall. On average, fully OA prices are around 64% of those of hybrids. This is a couple of percentage points higher than long term trends. Around 31% of our sample of fully OA journals charge no APCs. (We have separately analyzed the number of articles in OA journals.) Price rises vary significantly by discipline. Arts & Humanities and Social Sciences have seen particularly large average increases, especially in fully OA journal prices. Price Distribution Market-wide headline price changes mask important nuances. We have discussed previously that the most important nuance lies in the spread of prices within a given publisher’s portfolio. For example, if the bulk of a publisher’s journals lie toward the lower end of its pricing, with just a few journals priced at the high end, the average (mean) price will be higher than most authors pay. The following figures show how the spread of prices plays out in the market across our sample of publishers. The figures are outlines of histograms, showing how many titles sit in various price bands over the successive years of data we have curated. The red line shows the most recent year’s prices. The lines become greener as they go further back in time. Subscribers to Delta Think’s Data and Analytics Tool can see full details of axes. Hybrid Prices The spread of price bands for hybrid journals is shown in Figure 1 below.

User information needs as well as funding models are evolving rapidly, as evidenced by Clarivate’s recent move to phase out perpetual access purchases for print, eBooks, and digital collections by the end of 2025. Taking a hard look at how these assets contribute to your portfolio and overall organizational strategy has never been more critical. A holistic books program assessment can help you think intentionally about how books and book-based content can help meet customer and market needs. Publishing and Product Strategy A market-driven publishing and product strategy begins with an understanding of customer information needs. What markets, segments, information needs, and challenges are present? How can customer information needs be addressed? What role can our book content play? How can we differentiate our solutions? Can our book content contribute to a unique value proposition? Thinking creatively about how your content meets market needs is critical; think solutions, not printed pages and chapters. Commercial Strategy A detailed commercial strategy, supported by proper resources, is fundamental to success. Leveraging a clear understanding of customer preferences and delivering messaging that resonates with your specific market segments and use cases is essential. What are the best methods to generate market awareness? When and how should we communicate with key audiences? What messages resonate best? What sales and marketing capabilities do we have internally? Where do we need to partner to reach core audiences? How do we meet global needs? Do we have the appropriate access, pricing, and distribution models in place to meet customer expectations? What do we need to do directly? Where should we cultivate successful channel partnerships? And you don’t have to go it alone; a commercial strategy is best formulated and executed by a combination of internal and external resources. Technology Infrastructure Is your technology optimized to support your book program? From agile content management systems to product platforms to customer relationship management tools, the right tools enable your content and commercial strategy. What systems do we need to ensure efficiency in our publishing processes and quality and integrity in our content? What technologies and platforms do we need to build market-responsive products? What systems do we need to communicate effectively and meaningfully with our customers, including authors? Are we best served by building these systems or partnering? Successfully integrating and leveraging new technologies, such as AI, requires a fundamental understanding of markets and customer information needs . The Numbers Financial metrics are a key measure of the health of any program. An in-depth assessment of a program’s recent performance is a vital tool to help identify strengths, weaknesses, and gaps, and help to surface areas for improvement and corrective action. A financial analysis will clarify: What is our book and content annual output? Is it sufficient to support our strategy and meet customer and market needs? What is our cost structure? Our pricing strategy? Do they align with industry and market norms and expectations? Do we have the appropriate mix of internal and external resources in place to support our strategy? How can we best align our financial performance to contribute to the organization’s larger strategy? Beyond red ink or black ink, financial analysis will provide answers to these questions. Assessing Your Book Program Delta Think partners with publishers to do the foundational analysis necessary to understand how your book and book-based content can be a vital part of your content portfolio and support your organization’s goals and objectives. Our processes, including program benchmarking, stakeholder interviews, surveys, and workshops, combined with expert landscape research and analysis ensure you are building a content strategy that is market-focused and customer-driven. Contact Delta Think at info@deltathink.com to set up a time for a video call to learn more. We will also be attending the London Book Fair, March 11-13, 2025, if you’d like to schedule an in-person chat.

Overview A recent post on the Open Café listserv posed a question about the true extent of fee-free open access publishing, but it noted the incomplete coverage of the data cited. We have more comprehensive data, but just as we started our analysis, DeepSeek’s release sent markets into turmoil. The stage was set for a timely experiment. We first answer the question using our data. Then we see how the AI did. Background What proportion of open access is not paid for by APCs? In discussing this, a recent Open Café listserv post cited studies by Walt Crawford – a librarian, well-known in the academic library and OA communities for his analysis of open access. He has paid particular attention to “diamond” OA journals, which charge neither readers nor authors. His studies are based on data from the Directory of Open Access journals ( DOAJ ). Excellent though both sources may be – and, full disclosure, we contribute to the DOAJ – the DOAJ’s remit covers only fully OA (“gold”) journals. As listserv founder Rick Anderson noted, “By counting only articles published in DOAJ-listed journals, Crawford’s studies radically _undercount_ the number of APC-funded OA articles published – because DOAJ does not list hybrid journals, which always charge an APC for OA and which produce a lot of genuinely OA articles (though exactly how many, no one knows).” Using our data Actually, we do know … or at least have some fair estimates of hybrid OA. Our data allows us to determine the share of open access output in APC-free journals, as follows.

Overview Following the 2024 US election, the new US administration has instructed employees in some key federal agencies to retract publications arising from federally funded research. This is to allow representatives of the administration to review the language used, to ensure it is consistent with the administration’s political ideology. In this special edition of News & Views, we quantify how many papers might be affected and estimate their share of scholarly publishers’ output. The initial numbers may be small, but we suggest the effects on scholarly publishing could be profound. Background On 20 January 2025, Donald J. Trump took office as the 47th President of the United States. Within hours he signed an Executive Order 1 (EO) 14168 proclaiming that the US government would only recognize two sexes, and ending diversity, equity, and inclusion (DEI) programs inside federal agencies. The following day, his administration instructed federal health agencies to pause all external communications – “such as health advisories, weekly scientific reports, updates to websites and social media posts” – pending their review by presidential appointees. These instructions were delivered to staff at agencies inside the Department of Health and Human Services (DHSS), including the Food and Drug Administration (FDA), the Centers for Disease Control (CDC) and Prevention, and the National Institutes of Health (NIH). The events that followed are important, as they directly affect scholarly papers and our analysis. A memo on 29 January instructed agencies to “end all agency programs that … promote or reflect gender ideology” as defined in the EO. Department heads were instructed to immediately review and terminate any “programs, contracts, and grants” that “promote or inculcate gender ideology.” Among other things, they were to remove any public-facing documents or policies that are trans-affirming and replace the term “gender” with “sex” on official documents. By the start of February, more than 8000 web pages across more than a dozen US government websites were taken down . These included over 3000 pages from the CDC (including 1000 research articles filed under preventing chronic disease, STD treatment guidelines , information about Alzheimer’s warning signs, overdose prevention training , and vaccine guidelines for pregnancy). Other departments affected included the FDA (some clinical trials), the Office of Scientific and Technical Information (the OSTP, removing papers in optics, chemistry and experimental medicine), the Health Resources and Services Administration (covering care for women with opioid addictions, and an FAQ about the Mpox vaccine). Around this time, it further emerged that CDC staff were sent an email directing them to withdraw manuscripts that had been accepted, but not yet published, that did not comply with the EO. Agency staff members were given a list of about 20 forbidden terms, including gender, transgender, pregnant person, pregnant people, LGBT, transsexual, nonbinary, assigned male at birth, assigned female at birth, biologically male, biologically female, and he/she/they/them. All references to DEI and inclusion are also to be removed. The effects of the EO Commenting on the merits of policy and ideology lies beyond our remit. However, when these matters affect the scholarly record – as they clearly do here – then they are of interest for our analyses. Specifically, what might the effects of the EO be on the publication of papers, and what effects might accrue from withdrawal of research funding? If federal agencies are being instructed to withhold or withdraw submissions, then, to quantify what this might mean to publishers, we have estimated the volume of output from a few key federal agencies. It is summarized in the following chart.

Emerging technologies are reshaping how we create, distribute, and consume content. Publishers face the critical task of making smart technology investments to stay competitive and enable strategic objectives. How do you ensure that your next tech purchase aligns with your organization's needs and goals? Enter the needs assessment process – your roadmap to making informed, strategic technology decisions. From defining clear objectives to creating a comprehensive RFP, these best practices will help you navigate the decision-making process with confidence and ensure that your investments deliver value for your organization and your customers. Technology is not a solution; it is a tool. The temptation to adopt technology without a clear definition of what you are trying to achieve is an all too common (and usually very costly) mistake. Does your strategy include delivering a more personalized experience for your users? A customer data platform may be the right technology. Interested in using AI to build research integrity into your editorial process? Perhaps it’s time to revisit the capabilities of your editorial management system. Looking to support education and learning for students, faculty, and professional learners? Maybe it is time to evaluate formal learning management systems. Once you are confident about what you are seeking to achieve, the real work begins. Here are the key components that will help lay the foundation for a successful process from inception to deployment: Analyze Current State: Audit existing systems and processes to understand current capabilities and limitations. Conduct a Gap Analysis: Identify gaps between current capabilities and desired future state. Collect and Analyze Data: Gather qualitative and quantitative data from staff, users, customers, industry benchmarks, and about existing systems. Consider Resources and Constraints: Assess available resources, including budget, skills, and time. Research Solutions: Investigate potential technologies and/or types of solutions that could address identified gaps. Prioritize Needs: Work with stakeholders to prioritize needs based on impact and feasibility. Create RFP: After identifying prioritized needs and potential solutions, develop an RFP that clearly outlines project objectives, specific requirements, evaluation criteria, budget, and timelines. Distribute the RFP: Identify vendors with fit for purpose solutions and capabilities and distribute. Evaluate Proposals: Review vendor responses against established criteria and prioritize them based on how well they meet your needs. Plan for Adoption and Training: Consider the change management aspects of introducing new technology and processes. Be sure to develop a plan for user adoption, training, and ongoing support in your new systems. Technology as a Strategic Ally A methodical needs assessment is not just a procurement exercise – it is a strategic opportunity to reimagine how technology can transform your organization. The most successful technology investments are those that solve real problems, align with organizational goals, and empower your team to work more efficiently and creatively. Don’t fall into the trap of just moving what you are currently doing over to a new system. This is an ideal occasion to think about how you would design workflows and processes if you were to start from scratch and use that framework to evaluate the new capabilities available. You don’t want to duplicate what you are doing today; you want to step back and take the opportunity to build something better whenever possible. Customer Data Platform? Editorial Management System? Learning Management System? Something Else? Delta Think partners with publishers to do the foundational and implementation work required to ensure that technology decisions match the organization’s capabilities, fit the budget, and are grounded in voice-of-customer data. Our processes, including stakeholder interviews, surveys, and workshops, combined with expert landscape research, analysis, and assessments, underpin technology decision-making that is market-focused and customer-driven. If your 2025 objectives depend on or are enabled by technology, we’d welcome the opportunity to help you learn, plan, achieve. Please contact us today to start the conversation.

A number of sources provide information about patterns in the overall scholarly journals market. However, as we so often mention in our analyses, important nuances lie beneath the headlines. This month we explore just how much variation exists and highlight the importance of specificity. Background As part of our annual market updates, we estimate the proportions of open vs. subscription access content each year. Over the last few years, we have observed how OA has approached 50% of output, but we note that it has yet to punch through that number. However, this headline varies greatly depending on your area of publishing. An example from physics The chart below shows the nuances across just a few of the 200+ subjects that we track.

This month’s topic: How much content can AI legally exploit? Scroll down to read about this topic, along with the latest headlines and announcements. Delta Think publishes this News & Views mailing in conjunction with its Data & Analytics Tool . Please forward News & Views to colleagues and friends, who can register to receive News & Views for free each month. Delta Think will be attending several upcoming conferences, including APE (Jan 14-15), NISO Plus (Feb 10-12), and Researcher to Reader (Feb 20-21). We would love to see you there – please get in touch or visit our Events page to see all the meetings we will be attending. How much content can AI legally exploit? O verview During the recent PubsTech conference , we were asked how much content could be legitimately used to train artificial intelligence systems without being specifically secured through a licensing agreement. In considering this question, we find some counterintuitive results. Background Generative AI (genAI) is a type of artificial intelligence that can create new content—text, images, music, and more – by analyzing patterns in massive datasets. These models are typically trained on publicly available data scraped from the web. In the US, developers often invoke the “Fair Use” copyright doctrine to justify this training, claiming it is limited to specific purposes (training) and transformative in nature (different from the original use). In reality, the legal position is complex and evolving , with many rights holders and their representatives – unsurprisingly – taking the opposite view. Even if legal clarity emerges, different geographies and jurisdictions will likely reach different conclusions. The legal complexities of AI and copyright law are beyond our scope. However, for scholarly publishers, particular issues apply. Half of our output is open access , and open access content is designed to be reusable. Open or not, content has varying restrictions on onward use – for example, non-commercial use is often allowed with attribution. How much scholarly content is exploitable?  For the purposes of analysis, we will assume that the license under which content is published will have a material bearing on the legitimacy of its use to train AI systems. Therefore, looking at share of licenses, we might be able to answer our question.

Charleston Conference 2024 Reflections November always marks several noteworthy activities and events both personally and professionally, including one of our favorites – the Charleston Conference – where stakeholders from all areas of our industry – librarians, service providers, and publishers alike, get the opportunity to debate, collaborate, and share insights. Richard Charkin, OBE, described the Conference this way in his 2024 opening keynote remarks: “This meeting is incredibly important. Serious people debating serious issues.” We agree and add that the spirit of Charleston is also grounded in engagement – with colleagues and friends and making time for a bit of fun. Karaoke optional! Whether you were able to attend or not, here are some reflections on the 2024 Conference from the Delta Think Team. Libraries as Leaders – Lori Carlin The first thing that hit me was the energy of the conference overall; it was invigorating. Walking into the exhibit area on Vendor Day, you could sense a heightened level of interest from attendees eager to see and hear about new and interesting developments. Is it AI that is fostering this renewed energy? AI is certainly a hot topic, as stakeholders wonder how to best incorporate AI into their products, services, and workflows. Or perhaps the spotlight on Research Integrity and the various products that can help the scholarly community address these issues. Whatever the reason, I have always appreciated Charleston’s approach to exhibits, with a single dedicated day for vendors to showcase their wares, and the packed ballroom left no doubt that this concentrated attendee/vendor time was appreciated by all. As for sessions, the Opening Keynote featuring Katina Strauch and Richard Charkin was interesting – both bringing their own sense of wit to their description of their different but equally circuitous paths to scholarly publishing and their eventual role as community leaders. I also have to call out a session I moderated – “Keeping Libraries as Central Players in an Evolving Teaching and Learning Space,” and not because I moderated it! It was the librarian panelists as well as the interaction from the audience that made this session lively and interesting. What it reinforced for me is the leadership role librarians now play as not only information resource agents and gatekeepers in their communities, but data analysts, policy drivers, and educators, ensuring that advancements in teaching and learning are recognized and implemented. Books and eBooks in the Spotlight – Diane Harnish There was a noticeable “buzz” at Charleston around eBooks and book-based content. Whether for teaching and learning or research usage occasions, the value of book collections, or exploration of evolving funding models and roles, books were top-of-mind for librarians and publishers. For example, “Whose Future Is It? Practical Strategies for Supporting Community-led Open Access Book Publishing” focused on how libraries can take a leadership role in open access book publishing. The concurrent session was full of practical insights into how libraries develop effective strategies to support community-led and academy-owned OA book publishing, with an emphasis on equity. On a more macro-scale, Niels Stern, Managing Director, DOAB & OAPEN Foundation led a Neapolitan discussion entitled “Open Access Policies for Books: Librarian Roles in Nudging Institutional and National Change” which explored the work of the recently concluded PALOMERA Project, an initiative to examine and analyze the research policies and strategies for open-access books in 39 countries in the European research area. The project generated evidenced-based, actionable recommendations to “help ensure that books don't get ‘left behind’” in a global move toward open research. I found this session ideal for any stakeholder – library, funder, or publisher – interested in ensuring sustainable infrastructure for eBook, especially scholarly monographs. After more than 30 years in scholarly communication, this was my first Charleston and I will definitely be back! Research Integrity + AI and Copyright – Heather Staines Working closely with Dr. Elisabeth Bik and Dr. Ivan Oransky to explore research integrity issues was timely and enlightening. While there are many new tools to detect misconduct, both agreed that focusing on the human factor will be key—seeking change in research assessment and the kinds of publications that count. Their Neapolitan, “Challenges and Opportunities Around Research Integrity: A Conversation” session provided an informative overview of some of the most biggest challenges to research integrity (image manipulation, paper mills) and how Retraction Watch, COPE Guidelines, and other tools can be used by all stakeholders to raise awareness and help ensure the integrity of the scientific record. The other session which kept my interest was the “Long Arm of the Law” moderated by Ann Okerson. Copyright Clearance Center’s Roy Kaufman helped scope out the legal issues related to AI companies using copyrighted content to train their LLMs and shed some light on cases related to copyright and LLM training currently winding their way through the courts. ITHAKA’s Nancy Kopans followed JSTOR’s perspective as an aggregator working to balance the rights of copyright holders and publishers with the needs of students, faculty, and researchers. Definitely an area to watch! Katina’s Legacy – Meg White Charleston founder and convener Katina Strauch has passed the torch, but her legacy is a reminder that there is always more to discover, learn, and tackle. She never slows down and in many ways, defines what it means to always be evolving, embodying a true growth mindset. Katina and Richard Charkin kicked off the conference with a “Fireside Chat” Keynote moderated by Richard Gallagher, President and Editor-in-Chief of Annual Reviews (and the new owner of the Charleston Hub). As Lori mentioned, these two trailblazers were meeting for the first time, but they reflected on shared pivotal moments in their professional lives, including the intersection of publishing and librarianship, as we have moved from the internet to digitization of content and collections, and now to AI. I had the pleasure of interviewing Katina as part of the Charleston Leadership Interviews and the ATG Podcast, so watch for that conversation coming soon at the Charleston Hub. Her passion certainly informs many of the key values we strive for here at Delta Think as we work with the scholarly communications community to LEARN, PLAN, ACHIEVE. Bravo! Finally, we offer our congratulations to writer, director, producer, and star Heather Staines and her merry band of players. Thank you for an entertaining look at libraries, publishing, education, research, academia, and more in “Schmetadata: The Musical” a light-hearted start to the Conference’s final day. Next Steps What were your “aha moments” at Charleston 2024? What are your organization’s biggest priorities and challenges for 2025 and beyond? At Delta Think, we believe in the power of collaboration and innovation to drive progress. We can help you embrace change and unlock your potential.

Overview Each year, Delta Think’s Market Sizing analyzes the value of the open access (OA) scholarly journals market. This is the revenue generated by providers or the costs incurred by buyers of content. We estimate the OA segment of the market to have grown to just over $2.2bn in 2023. This is only a marginal growth over the previous year. It is a small fraction of the long-term historical growth of the OA segment. A reduction in the output of the large OA-only publishers has had a profound effect on the market. It has benefited established publishers, who are seeing a growth in OA, even while the overall market softens. We expect this pattern to continue in 2024. Have we reached peak open access? Have the underlying drivers of OA changed? And are we now in an era of lower OA growth? Headline findings Our models suggest the following headlines for open access market sizing:
