A preprint is a version of a research manuscript published before peer review. Typically these documents and made freely available on large databases - preprint servers or repositories. Publishing a preprint aims to speed up the process of disseminating research, to generate a conversation around research and gain feedback from others.
Preprints have a number of benefits:
EarthArXiv (pronounced "Earth archive") is both a preprint server and a volunteer community devoted to open scholarly communication. As a preprint server, EarthArXiv publishes articles from all subdomains of Earth Science and related domains of planetary science. These publications are versions of scholarly papers that precede publication in peer-reviewed scientific journals. EarthArXiv is not itself a journal and does not evaluate the scientific quality of a paper. Instead, EarthArXiv serves as a platform for free hosting and rapid dissemination of scientific results. The EarthArXiv platform assigns each submission a Digital Object Identifier (DOI), therefore assigning provenance and making it citable in other scholarly works. EarthArXiv's mission is to promote open access, share open access and preprint resources, and participate in shared governance of the preprint server and its policies. EarthArXiv was launched on October 23, 2017.
