PNAS Format
Treat “PNAS format” as a live journal workflow. Confirm the article type, use current Author Center requirements and any official template offered for that workflow, and recheck the submission system before uploading because operational requirements can change.
For Proceedings of the National Academy of Sciences (PNAS), use the live PNAS Author Center and submission system. Article type, manuscript length, references, figures, data/materials requirements, and final formatting are controlled by current PNAS instructions rather than one permanent generic template.
Key details
Further guidance
Article Type
Do not apply a standard research-article layout mechanically to other PNAS contribution types; article-type requirements can differ.
Author Center
Start with the PNAS Author Center for the current article type, manuscript organization, length, figures, references, policies, and required statements.
Submission System
Use PNAS Central for the live upload workflow and operational notices. The system currently routes authors back to the Author Center for detailed instructions.
Templates
If using an official or linked template, treat it as a preparation aid and verify that its assumptions still match the current Author Center requirements.
Worked Example
Before submission, reconcile the manuscript against the current PNAS Author Center, then use PNAS Central to confirm the required files and metadata rather than relying on an old lab template.
