POSI fan tutte

Just over a year ago, Crossref announced that our board had adopted the Principles of Open Scholarly Infrastructure (POSI). It was a well-timed announcement, as 2021 yet again showed just how dangerous it is for us to assume that the infrastructure systems we depend on for scholarly research will not disappear altogether or adopt a radically different focus. We adopted POSI to ensure that Crossref would not meet the same fate.
