The Paperscape is an infographic designed by two physicists maps the hundreds of thousands of studies in arXiv, an open repository for physics, mathematics, computer science, quantitative biology, finance, and statistics papers that is maintained by Cornell University. It can be explored by panning and zooming. The papers are sized according to their number of citations and positioned according to their references/citations. Different categories of the arXiv are assigned different colours, and newer papers are more brightly coloured.
