The table shows universities and research institutes from
the U.K., U.S., Germany, and Canada--ranked according to the impact of the publications
of their researchers. Listed are the numbers of academic papers published between
1994-98 and the number of times the papers have been cited by other researchers.
The figures were compiled using data from Institute for Scientific Information.

Impact: The average citations per paper over five years.
Journal articles: The total number of papers published that ISI has recorded.
Citations of articles: The total numbers of citations of those papers during
the period.
Impact cf. World: The impact figure in the first column divided by the world
average. This "rebasing" makes it easier to see how good the top performers
actually are and to provide more comparability between fields.
