Most Preprint Servers Allow the Publication of Opinion Papers

Abstract

Abstract Preprints are not only a raw form of research presentation, but also increasingly used as a gateway of entry into peer-reviewed journals. Several preprint servers are in existence, and some serve specific thematic groups or specialties, while others have a broader thematic scope. In this letter, we examined 36 preprint servers in March of 2023, noting that the majority (27/36 or 75%) accept opinion papers, two have an unclear, unstated, or unknown set of policies, while seven, including some of the most popular (biorXiv, medRxiv, Research Square), do not explicitly accommodate opinion papers. We opine that it would be in the interests of those preprint servers that do not publish opinion papers or evidence-based opinion papers to modify their scope of manuscript types in order to expand their user base and attract more participating scientists, but also to provide a more holistic set of scientific publishing objectives that accommodates a wider and more inclusive range of views.
