Preprints.org
Preprints.org is a preprint service that enables researchers to make early versions of their research outputs permanently available in Open Access and immediately citable. Content on Preprints.org is not peer-reviewed, but can receive public or private feedback from readers. Citation is fostered as all preprints receive a unique digital object identifier issued by Crossref. When new versions of preprints are uploaded, they receive a different DOI. All preprints are published with a Creative Commons CC BY 4.0 licence.
