PNAS

Proceedings of the National Academy of Sciences (PNAS) is a leading peer-reviewed scientific journal that has been publishing since 1915. It is the official journal of the National Academy of Sciences (NAS), a private, nonprofit society of distinguished scholars. PNAS covers a broad range of scientific disciplines including biological, physical, and social sciences, and is renowned for its high editorial standards and rigorous peer review process. The journal is published weekly, with an emphasis on original research, commentaries, reviews, and perspectives. PNAS is widely considered one of the most prestigious multidisciplinary scientific journals in the world, alongside Nature and Science. Its articles are frequently cited and have a significant impact on the scientific community and public policy. The journal uses a unique 'contributed' submission process where NAS members may submit up to four articles per year, in addition to direct submissions. PNAS also features special issues and collections on topics of broad scientific interest. With a global readership and a strong online presence, PNAS plays a crucial role in disseminating cutting-edge scientific knowledge. The website pnas.org provides access to full-text articles, supplementary materials, and other resources for subscribers and members. Despite the high profile, the site employs access control mechanisms to protect its copyrighted content, limiting direct automated access. The journal's long history and consistent quality have made it an authoritative source in academic research.
