Computers gung ho? Responding to the OAPEN Library and DOAB’s response time 

The catchphrase ‘computer says no‘ is something most of us are familiar with; it’s frustrating when an digital system is not behaving the way we want. Lately, at OAPEN and the Directory of Open Access Books (DOAB) we are experiencing something else that might be described as ‘computers gung ho’.  

What was the problem? 

The OAPEN Library and DOAB received so many requests from automated systems that they drowned out genuine users. On Tuesday 25 March, the problem reached a tipping point for the OAPEN Library when we saw this happening for several hours. From 8:30 up until 12:00 the number of sessions on the OAPEN Library exploded from 15 per second to 1,500 per second. As a result, the average response time of the OAPEN Library dropped from 0.2 seconds to 1.2 minutes, rendering the service unusable. Thanks to the support of our hosting partner CERN, the system did not crash.

If you look closely at the graph, you can see that these peaks in sessions were not confined to one morning only. We now see this happening several times per day, but only for short periods. 

Why is this happening? 

The reason for these bursts is that AI systems are hoovering up the content in the OAPEN Library and DOAB. OAPEN and DOAB are not the only websites that need to deal with these type of visitors. Eric Hellman describes in his blog “AI bots are destroying Open Access” how this has become a problem for many providers of open access content. When your mission is to make knowledge as widely available as possible, blocking AI bots should not be a necessity. This leads to unintended consequences, for example, the Internet Archive can no longer save snapshots of MIT Press because of Cloudflare blocking. The problem is not confined to open access providers, but also those who work on open source software see the same thing happening

What can be done about it? 

Our goal is to continue providing unfettered access to a quality curated collection of open access books. There is no simple solution: the requests come from different addresses and mostly do not identify as bots. This makes it hard for us – and all others dealing with this issue – to distinguish between genuine users and AI tools ‘gung ho’.  

Together with our colleagues at CERN we are working on the resilience of our systems, to make sure they keep functioning. We are also investigating if there is a way to deal with the peaks in downloads in such a way that it will allow human readers to keep using the OAPEN Library and DOAB without interruptions.  

While we keep working on a solution, we thank you for your continued patience when our services are temporarily slower than usual. 

Guest post: SCOAP3 for Books Program 2025

This is a guest post written by the SCOAP3 Team, mirrored on the SCOAP3 website.

The SCOAP3 for books program aims to support the open access (OA) publishing of new  (“born-OA”) scientific monographs and textbooks that are relevant to the discipline of high energy physics (i.e. in the field of Physics, Mathematics, Engineering, Instrumentation or Computer Science as related to the high-energy physics community). 

Supported by contributions from members of the SCOAP3 Consortium, the program has funded the Open Access publishing of almost 100 books to date (see the SCOAP3 Collection in the OAPEN Library)

SCOAP3 now launches the 2025 program and invites all interested scholarly publishers to participate. 

If you wish to participate in this program in 2025, we invite you to submit proposals for Open Access funding for books relevant to high energy physics that are planned to be published in the years 2025 and 2026, via the online form linked here.

Please fill one form per book, before May 15th, 2025. All the submitted books should already have been peer-reviewed and accepted for publication within the next 18 months, and should be accompanied with a significant amount of sample text (at least one chapter). 

In addition, it is mandatory that the prior consent of authors for OA publishing be obtained for each proposed title (using either CC-BY or CC-BY-NC license), together with their acknowledgement of the publication timelines required by the program (Publication should happen at the latest by December, 31st, 2026). 

Proposals will be subject to an evaluation by a panel of scientists in the field, who will make the final selection.. 

We aim to complete the selection process and inform publishers of the titles that have been successfully selected for funding by October 1st 2025. (Please note that books published before this date will not be eligible for SCOAP3 funding).In case of questions, or problems when filling the form, please contact us: scoap3@cern.ch.

Migrating the OAPEN Library and DOAB to CERN

This week, we will be migrating the OAPEN Library and Directory of Open Access Books (DOAB) servers from their current provider to CERN’s Data Center (as announced earlier this year). This move will improve the operational reliability and efficiency of services for the OAPEN Library and DOAB. 

At the same time, we are removing the EGI authentication for publishers from DOAB. As a result, participating publishers will need to request a new password when logging into DOAB.  

Timeline of events for the migration

  • On Tuesday 10 December, we will restrict updating access for publishers on DOAB, and we will pause adding new titles to the OAPEN Library. 
  • From Wednesday 11 December until Friday 13 December, we will be migrating the OAPEN Library and DOAB to the CERN Data Center. During this time, there might be a short disruption of availability to these services.  
    • We will copy the remaining data from the old to the new environment.
    • Once this operation has been completed, we will perform a final check.  
    • When the inspection proves to be successful, the web addresses https://library.oapen.org and https://directory.doabooks.org will be redirected to the new environments at the CERN Data Center. 
  • From Friday 13 December onwards, the OAPEN Library and DOAB will once again become available for updates. 

DOAB: removal of the EGI authentication 

Removing the EGI authentication service from DOAB will simplify our login process for participating publishers. Instead of the EGI authentication, publisher access to DOAB will be based on a combination of email address and password. A one-time update of the password will be required. This can be done by simply requesting a new password when logging into DOAB.

What does this mean for publishers hosting titles on OAPEN and/or participating in DOAB? 

If you are a publisher, you will not be able to add new titles or update existing titles to the OAPEN Library or DOAB between 11 December and 13 December. For those publishers participating in DOAB, they will need to request a new password when logging in as the EGI authentication will be removed.

For everyone else, you can continue to use the OAPEN Library and DOAB as usual but there may be some periods of time when the services are unavailable. We will try to keep these periods of unavailability as short as possible. 


We thank you for your continued patience with us while we navigate to our new service provider and look forward to completing migration. Please contact us with any questions.  

Strong Foundations for The Palace Project: A collaboration between OAPEN and Lyrasis

OAPEN and Lyrasis build greater access to digital content using the Open Publication Distribution System (OPDS) standard to create interoperability between content providers and reading applications.

The Hague, Netherlands, 9 December 2024 – OAPEN and Lyrasis are happy to announce the implementation and integration of the OAPEN Library collection with The Palace Project. Through this joint effort, more than 22,000 open access books have been made available through OAPEN’s Metadata Export Module for Open Access books (MEMO). This open source metadata management and integration tool by OAPEN invests in the principle of open and interoperable community owned infrastructure and is built on open standards and licensing of content. 

Ronald Snijder, CTO and Head of Research at OAPEN says, “I am very happy that our collection of peer-reviewed open access books is also available to The Palace Project users. We think it is important that our collection can be accessed through a platform like the Palace eReader App that is open and easy to use and that also reaches audiences beyond academia.”

Using OPDS, content providers have a simple and easy-to-implement tool to open discovery and access to other applications and reading systems. Because The Palace Project makes extensive use of OPDS with commercially licensed and openly licensed providers, OAPEN joins a growing global network of content providers invested in creating seamless access to content to readers, researchers, and scholars.   

“NYU Libraries is thrilled that OAPEN is now offering OPDS feeds through their MEMO service,” Nancy Lin, Senior Data Project Strategist at NYU Libraries tells us, “Using this open standard feed, Lyrasis was able to instantly integrate over 22,000 open access ebooks into NYU’s Palace eReader App.” 

James English, Director of Business Development at Lyrasis says, “We are excited to partner with OAPEN to expand access to their ebook collections and publisher content via the Palace App. We hope to broaden adoption and use of this valuable collection of knowledge and information in support of the open access publishing movement as The Palace Project and Lyrasis. I am particularly excited about OAPEN’s use of the OPDS standard in this integration as part of a growing movement toward creating an open and interoperable infrastructure for digital content in libraries.”

An Interview with the University of Oxford, Bodleian Libraries

The Bodleian Libraries at the University of Oxford recently became a premium OAPEN Library and DOAB supporter. Silke Davison, Community Manager, interviewed David Watson, the Bodleian’s open monograph project officer about their engagement with OA books and why they chose to become one of our supporters. Read on to find out what they had to say below!

You recently became a premium OAPEN Library and DOAB supporter, can you tell us your motivations behind this decision? 

Our decision to become a premium supporter of OAPEN Library and DOAB was driven by our commitment to the open access (OA) movement and our desire to ensure the widest possible sustainable access to research outputs including longform works. The Bodleian Libraries have a long history of supporting academic research, and we believe that open access is a vital component in the future of academic publishing. By partnering with OAPEN and DOAB, we hope to contribute to the growth and sustainability of open access publishing, particularly in the area of academic books. 

What are you looking forward to most about this collaboration? 

We are particularly excited about the opportunities this collaboration offers for enhancing the discoverability of OA books. Through our support, we hope to assist OAPEN and DOAB in expanding their platforms, making it easier for researchers and the public to access high-quality scholarly content. Additionally, we look forward to engaging with the broader OA community, sharing best practices, and contributing to the ongoing dialogue about the future of open access. This partnership also aligns with our goals of fostering innovation in research and ensuring that research is accessible to a global audience. 

How do you see this collaboration benefiting your institution? 

We see multiple benefits stemming from this collaboration. For the Bodleian Libraries, it strengthens our role in the open access movement, demonstrating our commitment to ensuring the widest possible access to research outputs. For our researchers and students, this partnership enhances access to a broader range of high-quality OA books, which is particularly valuable in an era where digital resources are increasingly vital for academic success. The OAPEN Open Access Books Toolkit (https://www.oabooks-toolkit.org/) is an extremely helpful resource for authors looking at publishing their books OA – which is a task we know can be daunting and confusing. 

How have the Bodleian Libraries responded to the rise of open monograph publication?

The Bodleian has recognized the significant impact that the rise of open monograph publication will have on Oxford’s academics and researchers, particularly in the humanities and social sciences. It also acknowledges the financial implications that the libraries must address. In response, the Bodleian Libraries launched the Sustainable Open Monograph Project to explore how best to navigate these changes, especially in light of the UKRI’s longform policy. The project has examined Oxford’s publishing landscape for OA books, raised awareness among academics about relevant policies, created an Open Book Collection within the institutional repository – ORA (Oxford University Research Archive), and supported OA book schemes, publishers, and infrastructure, all with the goal of fostering sustainable open access and promoting bibliodiversity.

A key focus of our efforts has been improving the availability of information about OA books to our academic community, helping to dispel misconceptions and build confidence in OA publishing. We have published several case studies featuring Oxford authors who have successfully published OA books, each highlighting different aspects of the OA publishing experience. In addition, we developed an author checklist that outlines the OA publishing process, offering practical guidance to authors considering open access for their monographs.

How do you see OA books developing in the next five years? 

In the next five years, we anticipate significant growth in the adoption and production of OA books.  As academic institutions, funders, and publishers increasingly recognize the value of open access – and with an open access requirement for submission of longform outputs confirmed for the REF exercise after REF 2029, we expect to see a broader range of disciplines embracing OA book publishing, especially in the humanities. Sustainable OA infrastructure will likely play a key role in this evolution, with improved platforms and tools making it easier to publish, discover, and interact with OA books. We also expect greater collaboration between libraries, publishers, and OA initiatives, with yet more innovative funding models and schemes. Ultimately, we believe that OA books will become a standard part of the academic publishing landscape – though there will be many within academia who will need to be convinced that OA is an opportunity, and not simply a burden.

OAPEN operates three platforms: the OAPEN Library, the Directory of Open Access Books (DOAB, in partnership with OpenEdition), and the OAPEN Open Access Books Toolkit. OAPEN promotes and supports the global transition to open access for academic books by providing open infrastructure services to stakeholders in scholarly communication.

Open access books – measured in a context

For over a decade, there have been open access books platforms. Each of those platforms share usage data and when you are an author of an open access book, you would find that it has been downloaded a certain amount of times. But how should you interpret that number? Unfortunately, the answer is not straightforward. The usage is influenced by the language of the title, its subject, but also by the platform: not all platforms reach the same audiences; furthermore, there might be seasonable differences. For instance, usage of the OAPEN Library is lower in the months of June to August, compared to September to November.

So, it would be helpful to have some clarity. A possible solution is a new metric – the Transparent Open Access Normalized Index (TOANI) score. It is designed to provide a simple answer to the question of how well an individual open access book or chapter is performing. The transparency is based on clear rules, and by making all of the data used visible. The data is normalized, using a common scale for the complete collection of an open access book platform and – to keep the level of complexity as low as possible – the score is based on a simple metric: the usage is either average, below or above average.

How does it work? As a proof of concept, we analysed the usage data of over 18,000 books in the OAPEN Library. Each book was assigned one high level subject, and the language was categorized as either English, German or Other languages. Each book was placed in a group that combined one subject and one language. Within those groups, we looked at the usage data, and determined whether a book was having average, more or less downloads.

Between groups, there are large differences: for instance, a German-language book on Humanities with 300 downloads is doing better than average, while an English-language book on Humanities would need to have reached at least 652 downloads to reach the same level. Another example is the difference between titles on Language in German versus other languages. Here, German-language books downloaded more than 250 times are scoring better than average. For books in other languages the bar is much higher: 385.

In this way, we can see how well a book is performing, compared to similar titles. In other words: when we consider the context of a book, we can actually say if its usage is better than expected.

Books in a bubble

Nowadays, we refer to “bubbles” as online places where no information from outside is allowed in. But in this instance, the opposite is true: the bubbles are a tool to help visualise how well one set of books is performing, compared to other sets of books. The OAPEN Library is an open online platform, and recently we have audited ourselves, based on the POSI principles. However, apart from an infrastructure, it is also a library.

When our collection passed the 20,000 titles milestone, we felt it was time to assess our collection: how well does it perform? That is not a simple question to answer: assessments of libraries and their collections are taking place within a certain context. OAPEN is not a ‘traditional’ library with a mixed collection of physical and digital publications, and our collection criteria are perhaps a bit different: books should be peer reviewed and have an open license, but we welcome all languages and subjects. We are not linked to one ‘parent organisation’, but try to serve everybody.

Three types of stakeholders support the OAPEN Library: publishers, funders and libraries. Both publishers and funders contribute to the collection by making publications available. They will be interested in the dissemination of the books and chapters. For libraries, the composition of the collection will be paramount. How do the titles on offer fit within the information needs of their patrons?

The evaluation of the OAPEN collection should consider these two aspects. The dissemination of books and chapters is measured through the number of downloads – based on COUNTER R5 conformant data. The composition of the collection is measured among two axes: subject and language. Both dissemination and the content-related aspects are paired to the number of publications. So, we have to take into account three dimensions: number of titles, number of downloads and average downloads per title. On top of that, we need to look at the differences between languages and subjects. All in all, a complex mix.

Our solution was to use three-dimensional pictures: the bubbles.

Usage of social sciences books depicted as three-dimensional bubbles

The bubbles display the composition of the collection and how its readers make use of it. Visualisations like this help to tell a complicated story in a simple way; a powerful instrument to guide the further development of the OAPEN Library.

Open Access Books – Helping small libraries think big

Over the last couple of years, the OAPEN Library and Directory of Open Access Books (DOAB) collections have grown significantly. We have seen more open access (OA) books being added, and welcomed new publishers from around the world. Much of the continued momentum for OA books has been made possible thanks to the support of a growing library community: investing in OA book programmes, infrastructures and services that enable not only the availability of these books in an OA format, but also their discoverability, preservation and integration into everyday workflows. 

Today, we are speaking with David Dusto, Electronic Resources Librarian at the Elizabeth City State University to learn more about their engagement with OA books.

David, thank you for agreeing to share your story with us. Libraries worldwide increasingly include our collections in their library catalog. These range from large academic libraries to specialized libraries attached to research institutes as well as smaller colleges. For those unfamiliar with Elizabeth City State University, could you share a bit more about the University and its library?

Elizabeth City State University (ECSU) is a public university that is part of the University of North Carolina system. With just over 2,000 students, ECSU is one of the smallest universities in the system, and it is also a Historically Black College or University (HBCU) and approximately ⅔ of the enrolled students are minorities. Historically, ECSU started in 1891 as a teaching college, and still has a large education school. Today, ECSU is also known for its innovative aviation program. The largest U.S. Coast Guard base in the United States is also located in Elizabeth City, so we have many military students as well. The G.R. Little Library is the campus library. We have a small staff of 5 full-time librarians and two other permanent staff, and we work to meet the research and information needs of all the student body.

Could you share more about your role in the library and how you first became familiar with open access books?

I am the Electronic Resources Librarian, but my predecessor held the title “Serials Librarian”, which shows how rapidly academic libraries are changing. I first became familiar with open-access books while I was a graduate student at the University of North Carolina School of Library and Information Science over a decade ago, and have been avidly interested in the subject of both open access books and journals since then. I am also involved with the university’s institutional repository (NCDOCKS), which serves as an open-access collection for material published by students and employees at the university.

To what extent are OA books a part of your library’s strategy today?

ECSU is a small university and our budget for collection development is limited, but I have found that I can supplement our existing eBook collections by locating high-quality open-access collections and adding them to the library website and discovery system. This has been enormously helpful – usage statistics indicate that a considerable percentage of eBook views through the library website are from open-access items. Therefore, despite the small size of the library and its resources, I have been able to build a large and useful online collection for our students and faculty.

How can OA books further support your library and the institution’s mission?

It’s important for institutions such as DOAB to exercise quality control in what they add to their collection, in order for it to be as useful and relevant as possible. Ensuring that links are working correctly in OA directories will save librarians like me a lot of time and aggravation in the long run, as we won’t have to deal with authentication issues and access limits that we are often confronted with when working with subscription-based collections.

In recent years open access for books has gained momentum, yet starting from a small base with a long road ahead still. Do you have any particular expectations or wishes for the open access book community and how this may evolve in the coming years?

I hope to see more institutional support for open-access book publishing. The focus for OA materials that I have seen from universities is primarily focused on journals rather than books, and I would be pleased to see increased support from both university presses/publishing houses and also from smaller institutions that may not have their own press. This would give authors from smaller universities the opportunity to publish and raise the prestige of their own institution, rather than going through a central system press. Similarly, I would like to see increased support for open course materials, such as open-access textbooks. As textbook costs continue to rise, having open course materials not only available but also adopted by instructors would go a long way towards easing the financial burden for students while simultaneously increasing access to materials.
