Co-citation maps

[Bornmann Lutz]

Dear colleague,
 
I am looking for co-citation data or graphs. These data/ graphs should show the increasing exchange (or collaboration) between different science disciplines within the last years.
 
I would be very grateful for references to papers, reports, data bases etc.
 
Many thanks in advance,
 
Lutz
