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:

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. 

 

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
