What is a preprint server? [193]

A preprint server is an online repository where manuscripts are published, often preceding publication in another outlet. These servers may be operated by a journal publisher or an independent entity. Once posted on a preprint server, a manuscript is often assigned a digital object identifier (DOI) and, consequently, would be citable; is publicly available after posting; and may or may not be removed depending on the server’s policy. Many preprint servers support content changes made by authors using a versioning system; however, old versions of manuscripts may remain publicly accessible.
