(UNAM) and the Public Library of Science (PLOS) today announced a one-year agreement, brokered by Accucoms (PLOS’ regional representative),that will allow UNAM researchers to publish in PLOS ONE and other select PLOS journals[1] without incurring article processing charges (APC). Flat fee agreements and PLOS’ other models shift publishing costs from authors to research institutions based on prior publishing history and anticipated future growth with PLOS. The agreement with UNAM starts on January 1, 2023.
