An open access e-prints service in the fields of physics, astrophysics, mathematics, non-linear science, computer science, and quantitative biology.
arXiv.org (formerly xxx.lanl.gov) is an open access electronic pre-prints (e-prints) service that provides access to over 350,000 pre-publication scholarly works in physics and related disciplines, including: astrophysics, mathematics, non-linear science, computer science, computational linguistics, neuroscience, quantitative finance, statistics, and quantitative biology. It is operated and primarily funded by Cornell University. While not traditionally peer reviewed, arXiv.org uses an automated endorsement system: current members of arXiv.org scientific communities endorse new submitters. The database can be searched by keyword, as well as browsed by subject or date. Updated regularly.
