    NOTE:  This is an earlier version (2002) of the data obtained from             
    Sep Kamvar, Stanford (2003) (the Kamvar/Stanford_Berkeley graph                
    in the UF collection, matrix ID 980).

    Nodes represent pages from and domains and directed   
    edges represent hyperlinks between them. The data was collected in 2002.

                        I obtained the Kamvar/Stanford_Berkeley directly           
                        from Sep Kamvar.  It is slightly smaller than the          
                        version in SNAP.  It is thus likely that Sep created       
                        multiple versions of the graph.
