arXiv is an archive of full text journal articles in the areas of physics, mathematics, and computer science.

The mathematics arXiv was formed from a number of smaller mathematical archives, with some in the arXiv system and some elsewhere, at the beginning of 1998. The system as a whole has over 200,000 articles in physics, over 20,000 in mathematics, and over 2,000 in computer science. The ultimate goal is to distribute all new research literature in all three disciplines worldwide, to store it permanently, and to keep it freely available.
