**Summary:** Scientific publishing is evolving to make research more accessible, but not all Open Access (OA) models are equally fair or sustainable. Green and Gold OA still rely on commercial publishers and often involve hidden costs for researchers or institutions. Diamond OA, by contrast, is community-led, free for both authors and readers, and keeps research as a public good. **Read the article: [https://doi.org/10.57035/journals/sdk.2026.e41.2397](https://doi.org/10.57035/journals/sdk.2026.e41.2397)** The article also includes an updated diagram of the main OA publishing models and an interesting graphic (see image) showing **Figure 2 – _Estimated contributions of key stakeholders across scholarly publishing models_**. The spider chart compares the roles of libraries, funders, researchers, publishers, and societies across different models. ![Vaucher, R., & Thomas, C. (2026).
