Covered areas include physics and related disciplines, mathematics, nonlinear sciences, computational linguistics, and neuroscience.
Authors can update their submissions if they choose, though pervious versions remain available.
Users can also register to automatically receive a listing of newly submitted papers in areas of interest to them, when papers are received in those areas. These listings are sent by e-mail. The archive receives 25,000 papers each year. Most of the new results in Physics first see the light of day here. There is a similar archive for the Cognitive Sciences at Cogprints and there is one for education at Education-online .
