Researchers began to exchange emails containing preprints, quickly hitting their strict disk space allocation limits \cite{Ginsparg_2011}. To address this problem, an automated email server initially called xxx.lanl.gov was set up on August 14th, 1991. This service would allow researchers to automatically request preprints via email as needed. It would soon become one of the world's first web servers and, renamed arXiv in 1998, today still serves as one of the most open and efficient forms of research communication in the world.
