The Proceedings of the National Academy of Sciences of the United States of America (PNAS) has entered into an agreement with non-profit electronic archiving service provider Portico to preserve its journal.
Through this agreement, PNAS seeks to ensure that its e-journal will be preserved and available for future scholars, researchers, and students.
PNAS claims to be one of the world's most-cited multidisciplinary scientific serials. Since its establishment in 1914, it has published cutting-edge research reports, commentaries, reviews, perspectives, colloquium papers, and actions of the Academy. Coverage in PNAS spans the biological, physical, and social sciences.
Portico will act as a perpetual access mechanism for this title.
