A comment to the papers by Opthof and Leydesdorff, Scientometrics, 88, 1011–1016, 2011 and Waltman et al., Scientometrics, 88, 1017–1022, 2011

The motivation for this is the recent exchange in the pages of this journal from two groups that have taken different positions on how normalization should be done.
