A detail list of number of authors, publication output and citation were shown in Figure 2 and it clearly indicated independent and small group were the most often method of collaboration. Annual publication output and CPP from 1982 to 2002 Publication output, citation and CPP of top 10 publishing countries Publication output, citation and CPP of publishing states in USA In-: International collaboration, Na-: National collaboration, No-: Independent, P: Publication, C: Citation, CPP: Citation per publication Publication output and citation of various number of authors Conclusion The yearly production showed a progressive increment with a domination of small group collaboration. USA has dominated publication production and followed distantly by United Kingdom where the seven major industrial countries still composed majority of the total production. ‘Moncada, S., Palmer, R.M.J. and Higgs, E.A.
