***** To join INSNA, visit http://www.insna.org ***** Yes, scientific specialties and disciplines can excellently be mapped using aggregated journal-journal citations as available from the producers of the Science Citation Index (the Journal Citation Reports). These citations follow a powerlaw distribution, but not in the interesting part of the distribution, that is, the core set of journals which shape specialties (let's say the first 20-50 most cited journals). I brought Pajek files online for all journals in the (Social) Science Citation Index at http://www.leydesdorff.net/jcr03/cited .
