Between 2003 and 2007, Thomson Reuters indexed 141,118 papers that listed
at least one author address in Spain. Of those papers, the highest
percentage appeared in journals classified under the heading of space
science, followed by agricultural sciences and mathematics. Spain's
relative impact in space science, as the right-hand column indicates, was
7% above the world average for the five-year period (8.32 citations per
paper for Spain versus the world mark of 7.80 cites). Meanwhile, the impact
of Spanish research exceeded the world average in several other of the
fields above, notably in physics (26% above the world mark), agricultural
sciences (11% above), clinical medicine (+11%), and engineering (+10%). In
plant & animal sciences, the impact of papers from Spain-based authors
happened to match the world average precisely: 3.21 cites per paper..
