abstract: In the table shown in the Briefing "Who leads the (Ivy) League in " 'citation impact'? " (9 Mar., p. 1183), the figures shown in the columns for "Citations" and "Citation impact" for Cornell University were incorrect. They should have been "523,878" and "16.53," respectively. The ranking was correct."
