Abstract: Author research impact was examined based on citer analysis (the 
number of citers as opposed to the number of citations) for 90 highly cited 
authors grouped into three broad subject areas. Citer-based outcome measures 
were also compared with more traditional citation-based measures for levels of 
association. The authors found that there are significant differences in citer-
based outcomes among the three broad subject areas examined and that there 
is a high degree of correlation between citer and citation-based measures for 
all measures compared, except for two outcomes calculated for the social 
sciences. Citer-based measures do produce slightly different rankings of 
authors based on citer counts when compared to more traditional citation 
counts. Examples are provided. Citation measures may not adequately address 
the influence, or reach, of an author because citations usually do not address 
the origin of the citation beyond self-citations.
