US institutions dominate the top portion of this ranking, taking a total of 16 slots in the listing of 20. IBM Corporation is here considered a global organisation. Germany, Switzerland and Denmark complete the list, with one institution apiece represented. Of course, the Max Planck Society represents many locations. Among the 16 US institutions listed, half are located in California.

The data above were extracted from Thomson Scientific’s Essential Science Indicators database. This database, currently covering the period January 1997 to December 2007, surveys only journal articles (original research reports and review articles) indexed by Thomson Scientific. Articles are assigned to a category based on the journals in which they were published and Thomson Scientific’s journal-to-category field definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Naturally, institutions publishing large numbers of papers have a greater likelihood of collecting more citations than scientists publishing fewer papers. This ranking is by citations per paper (impact), among those institutions that have collected 10,000 or more citations in engineering journals. For papers with multiple institutional addresses, each institution receives full, not fractional, citation credit. Essential Science Indicators lists institutions ranked in the top 1 per cent for a field over a given period, based on total citations. For the current version, 995 institutions are listed in the field of engineering, meaning that 99,500 institutions were reviewed to obtain these results. Of the 995, 80 institutions collected 10,000 or more citations in engineering. For more information on Thomson Scientific’s Essential Science Indicators, see Also see:
