arXiv is a free distribution service and an open-access archive for nearly 2.4 million scholarly articles in the fields of physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. Materials on this site are not peer-reviewed by arXiv.

The Computer Science Research Network on SSRN is an open access preprint server that provides a venue for authors to showcase their research papers in our digital library, speeding up the dissemination and providing the scholarly community access to groundbreaking working papers, early stage research and even peer reviewed or published journal articles.

engrXiv (Engineering Archive) is dedicated to the dissemination of engineering knowledge quickly and efficiently. engrXiv was launched in beta in July 2016 under the direction of Devin R. Berg, professor of mechanical engineering at the University of Wisconsin-Stout. The server is operated by Open Engineering Inc., a 501(c)(3) non-profit, which provides financial support for server operations.

TechRxiv (pronounced "tech archive") is an open, moderated preprint server for unpublished research in the areas of engineering, computer science, and related technology.
