List of terms for Science publishing
An electronic preprint or postprint. The term was coined in 1992, and originally referred only to electronic preprints. Paul Ginsparg [founder of arXiv [link: http://arxiv.org/] , an open-access repository of physics papers] later generalised it to mean author self-archived electronic preprints or postprints.
