Sage Journals Citation Maps
Pretty cool. I'm not 100% sure it's all that helpful (because it's only one way) but still pretty cool.
UPDATE: OOPs! Well that was shoddy work (by me). If you look at something that has actually been cited, you'll see that it does go both ways (duh)... further... it is apparently not all journals. Right now I see it in Communication Research but not Qualitative Research... So actually potentially helpful. (I went to WoS with no luck, then searched for Communication Research as a source title in Scopus, then limited to Communication research 2005-2006, and scanned the times cited to get one that was cited 5 times -- well Sage doesn't know about those 5 citations, so then I clicked on journal home and most cited articles). Along the right hand side, you get a listing of what authors and journals did the citing and you can download the whole list to your citation manager if you like. You can copy and paste the map, but if you use it in the page, the citations are all linked. This image is JOSEPH B.
