The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1998 to December 2008, 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 for those articles are for the period indicated.

Here we survey Italy’s output and citation impact relative to the world average in each field. Overall, Italy ranks eighth in the world in output, seventh in total citations, and eighteenth in citations per paper. The table above compares Italy’s citation impact in a specific field with the citation impact score for the world in the same field. Italy’s percentage above or below the world is presented in the column on the far right. Physics, agricultural sciences and space sciences rank as the top three fields for Italy relative to the world, according to citations per paper.
