Editing Preprint (section)

== Types of preprint servers ==
{{See also|List of preprint repositories}}The preprint servers can be grouped in three categories: general (accepting practically all preprints, frequently with bias towards some topic, publisher e.g. [[Authorea]]), field-specific (e.g. [[bioRxiv]], [[ChemRxiv]]) and regional (e.g. [[AfricArXiv|AfricArxiv]], [[Arabixiv]]). Additionally, preprints can be categorised by the owner (private publishing company e.g. ''[[PeerJ PrePrints]],'' libraries e.g. [[EarthArXiv]], universities e.g. [[arXiv]] or independent non-profit organisations e.g. [[HAL (open archive)|HAL]]). While many preprint servers appeared, some had been terminated. The canceled servers were operated mainly by profit publishing companies (e.g. [[Nature Publishing Group]] closed [[Nature Precedings]] or [[O'Reilly Media|O'Reilly]]&[[SAGE Publishing|SAGE]] closed [[PeerJ PrePrints]]) or were regional (e.g. [[INArxiv]] limited to Indonesia). Moreover, multiple writing platforms (e.g. [[Authorea]]) developed separate preprint servers as a part of their service.
