ISI (Thomson), Scopus (Elsevier) and now EBSCO with Citation Database searching

EBSCO "is now producing comprehensive citation indexing for literature in the disciplines of business, communication & mass media, nursing & allied health and sociology. Existing customers of EBSCOhost databases can now gain significantly improved access to citation indexing in these disciplines." via KnowledgeSpeak

I think with their new Grokker Groxis implementation we can expect some cool citation visualization fom Ebsco in the future.
