Between 2004 and 2008, Thomson Reuters indexed 167,402 papers that listed
at least one author address in Spain. Of those papers, the highest
percentage appeared in journals classified under the heading of
agricultural sciences, followed by space science and microbiology. Spain's
relative impact in agricultural sciences, as the right-hand column
indicates, was 19% above the world average for the five-year period (3.39
citations per paper for Spain versus the world mark of 2.86 cites). The
impact of Spanish research also exceeded the world average in several other
of the fields above, notably in physics (37% above the world mark),
chemistry (15% above), space science (+14%), engineering (+14%), and
materials science (+12%).
