OpenCitations is a plural: insights from the OpenCitations Community Survey

At OpenCitations, we have always described ourselves as community-driven and community-governed infrastructure. This definition deeply reflects our nature, since OpenCitations was born as a non-profit Open Science infrastructure to support open scholarship for the benefit of the scholarly community, and it continues to rely on that same community for its sustainability and governance, through memberships and participation in strategic decision-making processes. 

For this reason, it is essential for us that both our technical development and our outreach activities remain aligned with the real needs of the academic community. Over the past year, we have focused on strengthening our technical infrastructure and increasing awareness of OpenCitations’ values and activities. We are now entering a phase in which future priorities and developments need to be defined, at a time when the landscape of open citation services has become more crowded and complex. This makes it increasingly important for OpenCitations to clarify its positioning within the research ecosystem. 

To address this need, we came up with a simple insight: instead of assuming what the community needs, we decided to ask directly. This intuition led to the idea of launching a Community Survey. Developed with the support and guidance of the OpenCitations International Advisory Board, the survey was open to anyone in the academic community, including users, members, and people encountering OpenCitations for the first time. It was intentionally broad, covering both technical and outreach aspects. Its goal was not to evaluate performance, but to better understand how OpenCitations is perceived, used, and expected to evolve. 

The survey was open from 20 October to 16 December 2025, and we would like to sincerely thank everyone who took the time to respond and to help disseminate it within their networks. The feedback we received was of high quality, showing a strong level of engagement and a genuine willingness to provide thoughtful answers, especially through the open-ended questions. 

Respondents came from a wide range of backgrounds, primarily within academia and research, including researchers, librarians, information specialists, developers, and professionals working on research infrastructures and scholarly communication. Affiliations were mostly universities, research institutes, libraries, and non-profit infrastructures, reflecting a community already closely connected to Open Science practices. Levels of familiarity with OpenCitations varied considerably, from regular users to people who discovered the infrastructure for the first time through the survey. 

Across responses, OpenCitations was consistently associated with strong values such as openness, transparency, reproducibility, and independence from commercial interests. A recurring theme is the trust in the quality of the data and in the team maintaining the infrastructure. At the same time, awareness of specific services was uneven. While bibliographic and citation databases are relatively well known, more technical components such as APIs, data models, and SPARQL endpoints are mainly familiar to technically experienced users. 

This perception was reflected by usage patterns: OpenCitations often operates behind the scenes, with its data adopted within repositories and other scholarly tools. Citation analysis and metrics are another common use case, where OpenCitations is valued as an open alternative data source to proprietary databases. More specialised applications, such as knowledge graph construction and editorial workflows, were also mentioned, highlighting the flexibility of open citation data. 

When it comes to choosing OpenCitations over other databases, one of the strongest motivations is alignment with Open Science values. Respondents repeatedly emphasised the importance of open licences and the public-good orientation of the infrastructure. At the same time, several barriers remain, concerning in particular the limited coverage in certain areas, delays in data updates, technical complexity, and fragmented documentation. Another limit to adoption is the lack of awareness, together with institutional reliance on commercial databases. 

Regarding community engagement, awareness of OpenCitations often spreads through informal academic networks, conferences, workshops, and mailing lists. Active participation, however, remains limited, since many respondents follow OpenCitations’ activities without directly engaging. Still, there is a clear interest in deeper involvement, especially when it comes to contributing to Open Science, learning new skills, and aligning with institutional priorities around openness and transparency. 

Looking ahead, respondents expressed strong expectations around the expansion and enrichment of citation data, improved interoperability with other infrastructures, tutorials to support non-technical users, and more user-friendly interfaces. 

We are very glad to have opened this dialogue with the community. While some of the feedback confirmed issues we were already aware of, the survey also revealed we had not fully considered, particularly regarding how OpenCitations is perceived within the broader community. Overall, the Community Survey confirms that OpenCitations is widely recognised as a valuable and trustworthy open infrastructure for open science. At the same time, it highlights concrete areas for improvement, especially in usability, coverage, and community engagement. 

We see this survey not as a conclusion, but as a starting point for ongoing dialogue. The detailed results of the survey, including charts and word clouds, are available on Zenodo for public consultation:   

Di Giambattista, C., & Peroni, S. (2026). Summary Report of the OpenCitations Community Survey 2025. Zenodo. https://doi.org/10.5281/zenodo.18470862 

This survey now opens a phase of reflection that will inform future steps in our roadmap, and may also lead us to repeat this experiment in the future, exploring alternative formats for community engagement beyond surveys. Above all, we look forward to sharing concrete outcomes of this collaborative process with the community, as we continue to build OpenCitations with the community and for the community.

Opening Research Assessment

Final Conference of the GraspOS Project

12–13 November 2025

CNR Area della Ricerca di Pisa, Italy

We are pleased to announce the Final Conference of the GraspOS project: Opening Research Assessment, taking place on 12–13 November 2025 in Pisa, Italy.

For research assessment to truly support Open Science, we must prioritise transparency, inclusivity, and fairness in how we recognise research activities and contributions. This means not only ensuring that all contributions to Open Science are valued but also promoting openness in the data, tools, services, and other resources used in the assessment process.

The Conference will present the results of the GraspOS project and engage in discussions on transforming research assessment into a system that is open, responsible and aligned with the principles of Open Science.

Invited talks and expert panels will address critical topics for advancing a responsible research assessment system that fully embraces Open Science principles including:

● Open infrastructures for responsible research assessment

● Transparent and inclusive assessment practices

● Recognition of contributions to Open Science

The event will be hybrid, free of charge, and registration will be required. A call for poster contributions aligned with these themes will open soon, and a detailed programme and registration link will follow shortly.

The conference will be followed by the final event of the CoARA Italian National Chapter on the afternoon of 13 November.

Stay tuned, and please save the date!

Find OpenCitations on Infra Finder, a new tool to discover and support Open Infrastructures

If you are a leader of a Library or a Research Institution and would like to learn more about the existing open infrastructures that could help your institution to evolve in the research environment, but you don’t know where to look for, you can now use Infra Finder, a brand-new tool aimed at foster discovery, adoption, and investment for open infrastructure services. Infra Finder is launched by Invest in Open Infrastructure (IOI), and is designed to be the go-to resource for anyone navigating the complex landscape of infrastructure services and standards enabling open research and scholarship. 

The tool stems from the feedback collected from the community after the launch, in 2022, of the Catalog of Open Infrastructure Services pilot project in 2022, from which IOI decided to re-envision what outcomes they could affect and rethink what solutions could look like, also by furthering the Open Science principles conveyed by UNESCO’s Recommendation on Open Science, the Principles of Open Scholarly Infrastructure, and other Open Science initiatives and guidelines.  

We are happy to announce that OpenCitations is among the 56 infrastructures which have accepted IOI’s invitation to be included in this first release of Infra Finder. During its development, IOI team has been constantly collecting feedback from the infrastructures involved, and has conducted user testing to understand how different people might approach it. In OpenCitations we believe that Infra Finder could serve as an helpful tool to make OpenCitations and the other infrastructure services more visible to a wider and diverse community. Infra Finder allows users to easily find and compare the catalogued services, and its intuitive use could work as a starting point towards the creation of a greater awareness of existing open infrastructures, thus leading users to further explore their features and services and, hopefully, to consider the possibility of support their sustainability. 

IOI is currently planning to include new services in Infra Finder: if you are part of an organization that would like to be included, you can apply by filling out their Expression of Interest form. IOI will give two identical webinars to share with the community more details about the background and features of Infra Finder and on how interested infrastructure services can express interest in being listed. Register here to the either slot:  

May 2, 2024, 1600 UTC / 12pm Eastern 

May 3, 2024, 1400 UTC / 10am Eastern (in your time zone) 

The IOI blog post for the launch is available at https://investinopen.org/blog/infra-finder-your-hub-for-finding-infrastructure-services-enabling-open-research-and-scholarship  

OpenCitations supports the Barcelona Declaration on Open Research Information for a fundamental transformation in the research information landscape

Research Information can be defined as an information (sometimes referred to as metadata) relating to the conduct and communication of research. This includes, but is not limited to, (1) bibliographic metadata such as titles, abstracts, references, author data, affiliation data, and data on publication venues, (2) metadata on research software, research data, samples, and instruments, (3) information on funding and grants, and (4) information on organizations and research contributors. Research information is located in systems such as bibliographic databases, software archives, data repositories, and current research information systems.  

Decision-making in science is often biased by the typology of research information, and too often is based on closed research information, which is locked inside proprietary infrastructures and run by for-profit providers that impose severe restrictions on the use and reuse of the information. As a consequence, errors, gaps, and biases in closed research information are difficult to expose and even more difficult to fix. Indicators and analytics derived from this information lack transparency and reproducibility. Decisions about the careers of researchers, the future of research organizations, and ultimately the way science serves the whole of humanity, depend on these black-box indicators and analytics.  

There is an urgency for a fundamental change in the research information landscape towards openness. Indeed, open research information enables science policy decisions to be made based on transparent evidence and inclusive data and information used in research evaluations to be accessible and auditable by those being assessed. It makes it possible for the global movement towards open science to be supported by information that is fully open and transparent. 

Today, over 40 organizations, including the University of Bologna, are committing to making openness of research information the norm and to lead this change in the research information landscape. The signatories of the Barcelona Declaration on Open Research Information commit to taking a lead in transforming the way research information is used and produced, to make the openness of information about the conduct and communication of research the new norm. 

The full text of the Barcelona Declaration is now publicly shared on barcelona-declaration.org and presents the commitments that all the signatories of the Declaration adhere to, namely 

  • To make openness the default for the research information we use and produce; 
  • To work with services and systems that support and enable open research information; 
  • To support the sustainability of infrastructures for open research information; 
  • To support collective action to accelerate the transition to openness of research information. 

In addition to the signatories, the Declaration has been supported by several organizations providing data, services and infrastructures. OpenCitations has declared its support to the Declaration, together with AmeliCA, Crossref, Curtin Open Knowledge Initiative (COKI), DataCite, EuropePMC, DOAB, DOAJ, Europe PMC, Liberate Science GmbH, OAPEN, OpenAIRE, OurResearch, Redalyc and ROR. OpenCitations believes in the Declaration as a starting point for a substantial change by promoting values which OpenCitations fully supports, as stated in the words of our Director and Associate Professor at the University of Bologna Silvio Peroni:  

Since its creation in 2010, OpenCitations has always advocated and actively worked to produce open research information and develop infrastructural technologies to maximise its sharing and reuse in different applicative contexts. Thus, we embrace the Declaration’s goals and commitments and look forward to working with all the signatories to foster the use and production of open research information.

Prof. Silvio Peroni has been a part of the initial team of over 25 research information experts, representing organizations that carry out, fund, and evaluate research, as well as organizations that provide research information infrastructures, which first prepared The Barcelona Declaration on Open Research Information. The group met in Barcelona in November 2023 in a workshop hosted by SIRIS Foundation. The preparation of the Declaration was coordinated by Bianca Kramer (Sesame Open Science), Cameron Neylon (Curtin Open Knowledge Initiative, Curtin University), and Ludo Waltman (Centre for Science and Technology Studies, Leiden University).  

As of April 15, 2024, the list of signatories involves universities and other research performing organizations such as Αthena Research Center (Greece), Charles University (Czech Republic), Coimbra Group (international), Hamburg University of Technology (Germany), I-CERCA – Centres de Recerca de Catalunya (Spain), Instituto Brasileiro de Informação em Ciência e TecnologiaIbict (Brazil), Leiden University (Netherlands), Museo Galileo. Istituto e Museo di Storia della Scienza (Italy), Otto-Friedrich-Universität Bamberg (Germany), Sorbonne Université (France), Spanish National Research Council – CSIC (Spain), Udice – French Research Universities (France), UnilLaSalle (France), Universidad de Antioquia (Colombia), Università di Bologna (Italy), Universitat de Barcelona (Spain), Universitat Politècnica de Catalunya (Spain), Université Grenoble Alpes (France), Université Le Havre Normandie (France), Université Paris Saclay (France), University of Coimbra (Portugal), University of Groningen (Netherlands), University of Maribor (Slovenia), University of Milan (Italy), University of Poitiers (France), University of the Azores (Portugal), University of the Balearic Islands (Spain), University of Turku (Finland), Vrije Universiteit Amsterdam (Netherlands); research funding organizations and governments, including Bill & Melinda Gates Foundation (US), Catalan Foundation for Research and Innovation – FCRI (Spain), Dutch Research Council NWO (Netherlands), French Open Science Committee (France), French National Research Agency – ANR (France), Fundació Internacional Josep Carreras (Spain), Région Normandie (France), Regione Toscana (Italy), ZonMw (Netherlands); other organizations: Consorci de Serveis Universitaris de Catalunya – CSUC (Spain); EOSC Association (international), Latin American Council of Social Sciences – CLACSO (international), National Open Research Analytics, Technical University of Denmark (Denmark), State Scientific and Technical Library of Ukraine (Ukraine), TIB – Leibniz Information Centre for Science and Technology and University Library (Germany), UK Reproducibility Network – UKRN (UK). 

There is a need for global and concrete action to reach the tipping point in the transition from closed to open research information, and the Barcelona Declaration on Open Research Information is open for signature by all organizations that carry out, fund, and evaluate research to support this transition.

OpenCitations needs you: support the change in research practices

In OpenCitations, we like to define our infrastructure organization as “community-based” and “community-driven”, and we really mean it. The support coming from the number of academic libraries and consortia coming after OpenCitations’ involvement in the 2nd SCOSS funding cycle has made it possible, starting from 2020, to make OpenCitations develop from a small university project based on time-limited grant incomes to being an open infrastructure globally recognized for the provision of open citation data and bibliographical metadata. We want to thank all our members and donors, for trusting our mission and sustaining OpenCitations activities with their continuous and generous support, despite the pandemic and post-pandemic times. 

While retracing our work in the last three years, we are astonished by the achievements our team has accomplished, and by how in such a limited time frame OpenCitations has approached David Shotton’s initial vision (who is one of the co-directors of OpenCitations), when he first shaped the project back in 2010. Here are just some of the technical developments that have marked the last years:

  • in 2021, COCI, the OpenCitations Index of Crossref open DOI-to-DOI citations crossed the threshold of one billion citations stored;
  • in 2022, we released the two new OpenCitations indexes of open citations, DOCI (citations from DataCite) and POCI (citations from PubMed);
  • we expanded our collection besides the citation data by releasing OpenCitations Meta, a database storing and delivering bibliographic metadata for all the publications in the OpenCitations Indexes, including the publication’s title, type, venue (e.g. journal name), volume number, issue number, page numbers, publication date, identifiers and details of the main actors involved in the document’s publication (the names of the authors, editors, and publishers); 
  • as of October 2023, OpenCitations Indexes contain information on 1.82 billion unique open citations. 

However, the most significant achievements for OpenCiations in the last years have been the creation of a prolific network of collaborations with other Open Science projects, such as OpenAIRE-Nexus, RISIS2 and GraspOS, and the establishment of a structured team, involving young researchers and PhD students, whose work at the University of Bologna has made it possible to work on the technical developments day by day. 

Our results are a strong indicator of the growing sensibility on the theme of the open provision of bibliographical metadata and citation data, of which Open Citations is at the forefront as a founding member of the Initiative for Open Citations (I4OC) and the Initiative for Open Abstracts (I4OA). The effort and awareness campaigns led by these initiatives, by DORA and the Open Science community as a whole, have led more and more publishers to a change of heart and to open their reference lists. OpenCitations is an integral part of an ongoing process of transformation of the research environment, and we have collected and interpreted some of the needs of the academic community to plan our future activities and developments. We still need your help and support to make it possible to maintain and improve our infrastructure and to sustain the team working at OpenCitations

If you believe in

  • the importance of open bibliographic data for the creation of reproducible metrics for research assessment exercises
  • the power of the scholarly community to change existing practice by reclaiming ownership of its own data– and you want to become an active part of this change

please consider supporting OpenCitations either via membership or donation. You can find all the information on membership on our website at https://opencitations.net/membership, or you can ask for information by contacting us at membership@opencitations.net

Together, we can work to create an open and inclusive future for science and research. 

Thank You!

OpenCitations is part of the CoARA Working Group Towards Open Infrastructures for Responsible Research Assessment (OI4RRA)

Last March, the  Coalition for Advancing Research Assessment (CoARA) launched its call for members to propose Working Groups and National Chapters. The aim of the call (which was closed in June) was to foster the creation of Working Groups that would work as ‘communities of practice’ to enable systemic reform of research assessment by providing mutual learning and collaboration on specific thematic areas 

A group of 23 Coalition members, including University of Bologna’s personnel working at OpenCitations, collaborated in designing and proposing the CoARA Working Group Towards Open Infrastructures for Responsible Research Assessment (OI4RRA), focusing on having open infrastructures for making research assessment more transparent and responsible, and thus enabling the research community to be in full control of the data and indicators it relies on in assessments. 

We are now thrilled to announce that the proposed Working Group has been accepted, and will start its activities in the next months, with the mission to “enable institutions to move from proprietary infrastructure and research information, to open alternatives–in support of the transition to responsible research assessment practices. This effort will take into consideration the wide range of research outputs and open science practices and address the diversity of the global research community”. 

The CoARA Working Group Towards Open Infrastructures for Responsible Research Assessment will work to facilitate the use of existing open infrastructures, -, with the aim to make it possible a transition to a fully OI4RRA ecosystem – interconnected, decentralised and open –  that is fit to serve existing and emerging needs of reformed RRA agendas.  

For more information visit the dedicated section on CoARA’s website, and read the full list of participants in OI4RRA here 

The Dutch Research Council sustains OpenCitations

We are most grateful to the Dutch Research Council (NWO) for its commitment to sustaining the activities and developments of three SCOSS-selected infrastructures (PKP, OpenCitations and ROR) together with the Netherlands Reproducibility Network.

The selected infrastructures have been evaluated as “essential for a high-quality open science communication system”, and part of a network that “helps to promote reproducibility and strengthens the transition to open science”. OpenCitations, in particular, plays a strong role in reducing “the reliance on commercial products for doing bibliometric research and citation measurement” by providing an open database of citations.

This pledge carries out NWO’s enhancement of Open Science policy, as part of its strategy 2023-2026. The Dutch Research Council aims to support and encourage projects that put Open Science into practice, thus contributing to the transition towards a healthier research culture.

The yearly funding of 8000 EUR (year 2023-2025) will help us realise our planned future developments. Thank you, NWO!

Follow OpenCitations on Mastodon

OpenCitations has happily joined the open-source social media platform joinmastodon.org.

Mastodon is “a free and open-source software developed by a non-profit organization”, with the aim of favouring interoperability and bringing social media interaction “back in the hands of the people”.

New documents that present OpenCitations’ mission, unique benefits, present status and future plans

Posted on August 10th 2022 by Chiara Di Giambattista

More than a year ago, Ginny Hendricks, Director of Member & Community Outreach for Crossref, and a valued member of the OpenCitations International Advisory Board, published on the Crossref blog the post “The road ahead: our strategy through 2025”. In order to describe all Crossref’s principles and activities, Ginny presented the Crossref strategic planning framework as a diagram summarizing Crossref’s statements, key messages and truths. The clarity and immediacy of the diagram were such that we adapted it to present  OpenCitations’ own statements and goals. The resulting poster “OpenCitations – what does the future hold?” was presented by our Director David Shotton at the OASPA2021 conference, and can be found in this blog post.

Although the poster offered a wide overview of OpenCitations values, unique traits, benefits and plans, it differed slightly from Ginny’s original diagram, in particular because it lacked a “Mission Statement”, scattering the relevant information within the “Values” and “Principles” boxes. Indeed, at that time (September 2021), we didn’t have a clearly defined Mission Statement.

Nevertheless, the creation of that poster was crucial in helping us start to articulate more clearly the purpose and meaning of OpenCitations. As David underlined in his post “From little acorns…a retrospective on OpenCitations”, since 2018 OpenCitations activities have progressively increased and, with them, the number of related journal articles, conference papers and technical definitions. OpenCitations’ involvement in international networks and collaborations (such as SCOSS and the OpenAIRE-Nexus project), together with our need of identifying and reaching out to new stakeholders to assure OpenCitations’ development and sustainability, has made it necessary to publicly define OpenCitations’ mission, unique strengths and next developmental steps.

After numerous revisions, aided by wise advice from members of the OpenCitations Advisory Board members, we’re now happy to publish the following three OpenCitations documents:

OpenCitations Mission Statement,

The Uniqueness of OpenCitations   and

OpenCitations – Present Status and Future Plans,

which together provide a summary of why we exist and where we are heading.

We are particularly proud of the definition of OpenCitations’ primary mission, namely

to harvest and openly publish accurate and comprehensive metadata describing the world’s academic publications and the scholarly citations that link them, and to preserve ongoing access to this information by secure archiving.

The Mission Statement also presents brief descriptions of the OpenCitations context, our vision, our value proposition and our relationship with the community and stakeholders.

The Uniqueness of OpenCitations provides the answer to the question ‘Why choose to use OpenCitations?’, and is a detailed presentation of OpenCitations’ benefits.

OpenCitations – Present Status and Future Plans summarizes OpenCitations’ ongoing activities, that can be quickly visualized on our public roadmap. It also introduces the OpenCitations Working Groups, served by the members of the OpenCitations International Advisory Board, which are currently working on the themes of governance evolution and community building, with the common purpose of driving OpenCitations along the path from being a ‘sustainable infrastructure’ (in POSI terms) to being an enduring community led and financially sustained infrastructure.

In fulfilling our mission and reaching our goals, the support and vital interest of our community members is fundamental. We request that you, as a member of our community, provide us with feedback on these documents and the ideas they contain, or indeed to ask for clarifications, to help us improving our mission and our communications to explain it. You can reach us here: contact@opencitations.net.

Thank you!
