Barabasi/NotreDame_www (matrix ID 1510) in the UF Collection.                 
Nodes represent pages from University of Notre Dame (domain and       
directed edges represent hyperlinks between them. The data was collected in   
1999 by Albert, Jeong and Barabasi.

web-NotreDame.txt.gz    University of Notre Dame web graph from 1999          
NOTE: a similar version of this problem already appears in the UF Collection: 
web-NotreDame       Barabasi/NotreDame_www                                    
                    in SNAP/:       n: 325,729   nz: 1,497,134                
                    in Barabasi/:   n: same      nz:   929,849                
                    The Barabasi/NotreDame_www is an exact copy of            
                    the graph of that name in the Pajek data set.             
                    The SNAP collection has a different version of this       
                    graph, of which SNAP/web-NotreDame is an exact copy.      
                    It is possible that Barabasi's version of the graph is yet
                    a 3rd version of this graph.
