Preprint Policy
Prior to formal submission to a journal, USP permits and promotes early publication on accredited industry preprint servers for evaluation by other scientists. A cover letter that accompanies a manuscript submission must include information about any accession numbers and any preprint sites. USP prohibits all in-process or peer-reviewed revisions from being posted on preprint servers. A manuscript whose corresponding preprint version has been indexed (e.g., in MEDLINE or PubMed) will not be considered.
Once a manuscript has been accepted by a USP journal, authors should link all preprints to the final online publication in the journal.
