Bibliometrics can be fun!
With his world map of scientific collaboration, Oliver Beauchesne, from the US-Canada based Science-Metrix, has built nice visualizaion of science collaboration.
It is based on Scopus data. For those interested in looking at how scientists are connected geographically, a number of companies already promise to help map the geographic reach of an individual or a discipline. These include Springer’s AuthorMapper, Transinsight’s GoPubMed and BioMedExperts.
