1. Open access
All material published by Public Library of Science, whether submitted to or created by PLOS, is published under an open access license that allows unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
PLOS strives to set the highest standards for excellence in everything we do: in content, style, and aesthetics of presentation; in editorial performance at every level; in transparency and accessibility to the scientific community and public; and in educational value.
3. Scientific integrity
PLOS is committed to a fair, rigorous editorial process. Scientific quality and importance are the sole considerations in publication decisions. The basis for decisions will be communicated to authors.
Although pragmatic considerations require us to focus initially on publishing high-impact research in the life sciences, we intend to expand our scope as rapidly as practically possible, to provide a vehicle for publication of other valuable scientific or scholarly articles.
PLOS welcomes and actively seeks opportunities to work cooperatively with any group (scientific/scholarly societies, physicians, patient advocacy groups, educational organizations) and any publisher who shares our commitment to open access and to making scientific information available for the good of science and the public.
6. Financial fairness
As a nonprofit organization, PLOS charges authors a fair price that reflects the actual cost of publication. However, the ability of authors to pay publication charges will never be a consideration in the decision whether to publish. See our Global Participation Initiative for more information.
7. Community engagement
PLOS was founded as a grassroots organization and we are committed to remaining one, with the active participation of practicing scientists at every level. Every publishing decision has at its heart the needs of the constituencies we serve (scientists, physicians, educators, and the public).
PLOS aims to be international by removing barriers to the immediate availability, access, and use of its published research; and by engaging a geographically diverse group of researchers and medical practitioners.
9. Science as a public resource
Our mission of building a public library of science includes not only providing unrestricted access to scientific research ideas and discoveries, but developing tools and materials to engage the interest and imagination of the public and helping nonscientists to understand and enjoy scientific discoveries and the scientific process.
