Pre-Print Articles in AMA

Definition:

"Preprints are another online method for publication in which a manuscript is uploaded by authors to a public server, without editing or formatting, and typically without peer review. A preprint may be a predecessor to publication in a peer-reviewed journal; it is “archived” and citable. Preprint servers include arXiv.org, bioRxiv.org, MedRxiv, and many others." AMA 11th edition, Ch 3.11.4.1
