PLOS, or the Public Library of Science, is a nonprofit organization that promotes open access to scientific research. Founded in 2000, PLOS aims to make scientific findings freely available to everyone, allowing researchers, educators, and the public to access important information without paywalls. This approach encourages collaboration and innovation in the scientific community. PLOS publishes several peer-reviewed journals, including PLOS ONE and PLOS Biology, covering a wide range of disciplines. By providing a platform for researchers to share their work openly, PLOS helps to advance knowledge and improve the quality of science, making it more accessible to all.
