The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1999 through October 2009, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated.

This ranking is by citations per paper (impact) among those institutions that published 500 or more papers in molecular biology and genetics during the period. For papers with multiple institutional addresses, each institution receives full, not fractional, 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, 423 institutions are listed in the field of molecular biology and genetics, meaning that a total of 42,300 institutions were surveyed to obtain the results. Of these, 239 institutions published 500 or more papers. The ranking by citations per paper seeks to reveal “heavy-hitters” based on per paper influence, not mere output. US institutions account for 16 of the top 20 listings.
