Between 1995 and 1999, ISI indexed 162,935 papers that listed at least one author address in Canada. Of those papers, the highest percentage appeared in journals classified under the heading of geosciences, followed by ecology/environmental sciences and psychology/psychiatry. In all three of those fields, as the right-hand column
demonstrates—in fact, in all but a handful of the fields shown above, Canada's citations-per-paper average (or impact) surpassed the world average. In geosciences, for example, Canada's impact of 3.43 cites per paper was 7% above the world mark of 3.21 average cites. Even in fields in which Canadian researchers contributed papers at a rate below the nation's 4.74% overall share of the ISI
database—including clinical medicine, materials science, chemistry, and
physics—the impact of Canadian research exceeded the world average. In two fields, Canadian impact happened to match the world mark exactly: neuroscience (6.83 cites per paper) and microbiology (6.04 cites).
