PNAS announced on Twitter this week (September 5) that the publication would discontinue its print edition come January, and in July 2019, the journal will extend the page limit on manuscripts.
“Eliminating our strict sizing requirements will simplify the author submission and publication process, addressing a common complaint about submitting to PNAS,” Taylor Gedeon, a media coordinator at the journal, tells The Scientist in an email.
PNAS has had a six-page maximum, but in July will allow authors to go up to 12 pages for an additional fee. “Flexible article length is more in line with the majority of scientific journals, which do not enforce rigid page limits, and which charge an additional fee for articles exceeding a standard length,” Gedeon writes. Papers will not be able to go beyond 12 pages.
