There is an interesting "Atlas of Science" project that has been undertaken by the people that do the Science Citation Index. As far as I know, only the map for molecular biology has been published so far. As I recall, here is the procedure. The citations in the literature are analyzed for a certain period; those items cited most (from before the period) are singled out as "citation classics". Then the "distance" between research papers of the period is determined by the number of citation classics they cite in common. They find that research papers tend to fall into groups of closely related papers, which they call "specialties". But also they get a distance between specialties. Then they were able to arrange the specialties in a plane so that the distances were approximated. The result is a "Map" of the field of molecular biology. Here is the bibliographic information: ISI atlas of science: biochemistry and molecular biology: including minireviews of 102 research front specialties. 1978/80- Philadelphia, PA. : Institute for Scientific Information, 1981- v. : ill. ; 29 cm. -- Gerald A.
