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,
