Preprints

Types of preprint servers

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, 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). 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&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.
