Dear all
I am reading up at the PNAS submission instruction for authors, and contrary to my expectation, I did not see a limit for references for original research article. The only limit I saw was a maximum of 5 references for a letter. Can anyone confirm to this please? I am more confident if I read somewhere stating there is no limit rather than not seeing a statement about a limit.
Thank you so very much and have a lovely day.
Regards
