Network collection from M. Newman http://www-personal.umich.edu/~mejn/netdata/ The graph cond-mat contains the collaboration network of scientists posting preprints on the condensed matter archive at www.arxiv.org, 1995-1999, as compiled by M. Newman. The network is weighted, with weights assigned as described in the original papers. Please cite, as appropriate, one or more of: M. E. J. Newman, The structure of scientific collaboration networks, Proc. Natl. Acad. Sci. USA 98, 404-409 (2001). M. E. J. Newman, Scientific collaboration networks: I.
