Resum	Preprint servers are open-access repositories where researchers post manuscripts before, during, or alongside peer review at a formal journal. Preprints allow rapid, free dissemination of research findings without waiting for journal review (which can take 3–12 months). Major preprint servers include arXiv (physics, math, computer science; founded 1991), bioRxiv (biology; 2013), medRxiv (medicine; 2019), and others. Preprints are NOT peer-reviewed and should not be treated as final scientific evidence. However, they enable priority-claiming, feedback from the community, and rapid knowledge sharing in fast-moving fields. Many journals now accept manuscripts previously posted as preprints.	Open access (OA) publishing removes subscription paywalls, making research freely available to all readers online without subscription fees. The Budapest Open Access Initiative (2002) defined OA as the right to read, download, copy, distribute, print, search, and link research freely. Multiple OA models exist: Gold OA (immediate free access, often author-funded via APCs), Green OA (free self-archiving in repositories), and Diamond OA (free to both authors and readers). OA expands research impact, enables global participation in science, and aligns with public funding mandates. However, OA models vary in sustainability and are sometimes exploited by predatory publishers.
