The data above were extracted from the Essential Science Indicators database of Thomson Reuters, currently covering the period 1 January 1998 through 31 October 2008. This database 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 Thomson Reuters’ journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Naturally, scientists publishing large numbers of papers have a greater likelihood of collecting more citations than scien­tists publishing fewer papers. This ranking is by total citations. For articles with multiple authors, each author receives full, not fractional, citation credit. Another ranking could be based on citations per paper, which reveals weighted impact. Essential Science Indicators lists authors ranked in the top 1 per cent for a field over a given period, based on total citations. For these data, 2,358 authors are listed in the field of immunology, meaning that a total of about 235,800 authors’ records were reviewed to obtain these results.
