Special Issue Information

Dear Colleagues,

Diamond open access refers to journals that do not charge any fees for authors or readers. More ambitious interpretations include characteristics such as operating on a non-commercial basis or using licenses that exclude the commercial utilization of published content. Although journals offering free access without charges have existed for three to four decades and have become an alternative publishing model in some parts of the world, there is a renewed mainstream interest in such journals that has been triggered by science policy. This interest may stem from the limitations and shortcomings of other open access (OA) publishing models, particularly those based on article processing charges (APC) or publish-and-read (PAR) fees. While the OA transformation was accompanied by high hopes for cost reduction, many were disappointed by the lack thereof, leading to a search for alternatives. Despite the high relevance of diamond OA, relatively limited research has been conducted on this topic. However, this situation appears to be changing, as a number of research projects now focus on the topic following science policy initiatives.

Diamond open access journals have unique features that make them a fascinating topic to study. First, these journals are heterogeneous and employ different strategies to mobilize resources to sustain their operations. Sources include both voluntary labour and monetary resources acquired in a myriad of ways. Second, the composition of actors differs from commercial journals, where the journal titles are owned by publishing houses or published by them on behalf of an institute or a scientific society. In the case of diamond OA journals, a large diversity of settings can be observed, such as journals solely operated by a group of scientists, collaborations between scientists and libraries, or collaborations between scientists and publishers (as in the subscribe-to-open model). Third, the relevance of diamond OA journals in science policy discussions varies. In Latin America, the model was introduced and popularized early on; meanwhile, European and North American countries began implementing diamond OA relatively late, and in some countries, diamond OA journals are virtually absent. This diversity indicates that the framework conditions set by science policy differ on the global level, resulting in mixed results and achievements of the model.

Aim

Against the backdrop of the information introduced above regarding diamond OA, the aim of this Special Issue is to collect contributions that analyse diamond OA publishing models from all perspectives. It seeks to contribute to our understanding of the operation of such journals, explore their strengths and weaknesses, and assess their potential in different disciplines or country-specific settings. Contributions from all countries worldwide are welcome.

Possible Contributions

Possible contributions may include, but are not limited to, the following topics:

  • Theoretical works on the conceptualization of diamond OA;
  • Analysis of the relevance of diamond OA in science policies in different countries (as well as on the supranational level);
  • Studies of the operation of diamond OA journals, particularly the interplay of voluntary and paid work;
  • Investigations of the cooperation between scientists and providers of digital infrastructures for diamond OA journals;
  • Exploration of the current role and future potential of diamond OA journals in the publishing landscape and in the OA transformation;
  • Cross-country comparisons about the relevance and role of diamond OA journals.

Contributions may be theoretical or empirical and may apply quantitative, qualitative, or mixed methods approaches.

The Diamond Open Access (OA) model—characterized by the absence of fees for both authors and readers—has gained increasing attention in recent years. A wide range of scholarly journals are using this model, as emerged while mapping the Diamond OA landscape worldwide; however, some still depend on hybrid revenue streams such as print sales, subscriptions, and marginal APCs. A number of recent initiatives underlined the need to increase quality assurance, sustainability, and cooperation within the Diamond OA ecosystem. Among them, the Diamond OA Standard (DOAS), a framework comprising detailed guidelines and a self-assessment tool to facilitate Diamond OA publishing practices, was created by the DIAMAS project, sponsored by the European Commission. Annali dell’Istituto Superiore di Sanità, the official journal of the Italian leading public health research institution, is a Diamond OA journal. To improve transparency and quality, the editorial team used the DOAS self-assessment tool to evaluate its compliance with the standards proposed by DIAMAS and to identify potential areas for improvement. This article presents the process and findings of the DOAS self-assessment tool conducted on Annali ISS, with the aim of sharing insights and support with other journals seeking to align with the DOAS framework.

This study analyzes the impact of different Open Access (OA) publication models in engineering, comparing journals that charge Article Processing Charges (APCs) with those operating under the Diamond OA model. A total of 757 engineering OA journals, comprising 504 APC-based and 253 Diamond OA journals, were examined using bibliometric data from 2020 to 2023. The analysis focused on four key metrics: CiteScore, total citations, number of published articles, and the percentage of cited articles. The results indicate that APC-based journals dominate the upper quartiles (Q1 and Q2) regarding absolute citation counts, primarily driven by high-volume mega-journals such as IEEE Access. However, Diamond OA journals exhibit a higher proportion of cited articles (88.8% compared to 83.4% in APC-based journals) within the top 10% category. Despite their benefits in providing cost-free dissemination, Diamond OA journals account for only 8.4% of the 3012 active engineering journals indexed in Scopus, highlighting sustainability and visibility challenges. The findings suggest that, while APC-based journals achieve higher absolute citation counts, editorial reputation and visibility strategies significantly influence citation performance. This study contributes to the ongoing discussion on the financial sustainability and equity of OA publishing in engineering. Full article

This review paper reviews research literature on Diamond Open Access (DOA) journals—sometimes also called Platinum Open Access—that was produced after this journal segment started to become a priority in European research policy around 2020. It contextualizes the current science policy debate, critically examines different understandings of DOA, and reviews studies on the role of such journals in scholarly communication. Most existing research consists of quantitative studies focusing on aspects such as the number of DOA journals, their publication output, the diversity of the landscape in terms of subject areas, languages, publishing entities, indexing in major databases, awareness and perception among scholars, cost analyses, as well as insights into the internal operations of DOA journals. The review shows that research on DOA journals is partly influenced by the science policy discourse in at least two ways: first, through the normativity inherent in that discourse, and second, through the temporality of policy-driven research of practical relevance, which leaves important aspects of the phenomenon understudied. Moreover, research on the DOA journal landscape has implications beyond understanding this particular journal segment, as it also challenges established views of the global system of scholarly communication.

In the information society, open data is an important resource for creating economic value. This study conducts a systematic review, following the PRISMA methodology, of articles published between 2000 and 2025 in Scopus and Web of Science that include the terms Open Data and Spain (in Spanish or English) in their title and/or abstract, with the aim of assessing how Law 37/2007 on the reuse of public sector information has influenced the publications analyzed. After identifying 240 articles in Scopus and 109 in Web of Science and applying the exclusion criteria, we observe that 37 studies use the Diamond Open-Access publishing route. The results are organized into four categories corresponding to the research questions, which represent a meaningful theoretical contribution and enhance current knowledge on open data research in Spain. The identification of obstacles to the effective use of open data—such as the lack of standardization, poor information quality, and the vague definition of reuse conditions—entails practical implications of significant value for managers of open data portals seeking to improve their initiatives.
