Doing the right thing: PNAS decides not to embargo paper that had appeared as a preprint
On July 8, following a bit of a clumsy episode involving the Proceedings of the National Academy of Sciences (PNAS), I urged journals not to embargo papers that had already appeared as preprints.
A week later, this arrived in my inbox:
FOR IMMEDIATE RELEASE
Due to prior news coverage, PNAS is publishing the following study without an embargo.
A link to the published article may be found below.
