Preprints: Accelerating Research

2. Where Can I Find Preprints?

Preprint Repositories


Preprints are housed on servers that are commonly hosted by universities, non-profit organizations, and publishers. There are general preprint repositories, like arXiv; field-specific repositories like bioRxiv, EarthArXiv and ChemRxiv; geography-specific repositories like AfricArxiv; and preprint services integrated into publisher submission workflows like Research Square (Springer Nature) and Authorea (Wiley).

Preprint servers for physics, math and social sciences have existed for many decades. Servers for preprints in health and biomedicine are generally much younger. Some well-known biomedical preprint servers are bioRxiv, which launched in 2013, and medRxiv, which began accepting papers in mid-2019.
