All citations among the papers of these 11 journals were identified. Next the 57 most cited authors were selected, cited by at least 30 papers. The map below shows how they are co-cited.
Circles are proportional to number of citations, and the closer they get the more co-cited they are.
Lines and their thickness indicate co-citations. Below the center we see mostly bibliometricians, distributionists to the bottom left and people in science indicators and co-citation analysis at the bottom right. Moving up we find the information retrieval cluster at the center and on the right side a few authors in information seeking.
