Very recently, the Nature Index has been proposed and published. It offers the possibility to rank institutions and countries according to the absolute numbers of papers published in a selection of 68 journals. We discuss the main elements of the Nature Index, and we wish to start a discussion about the Nature Index by stating four main points of criticism. The main problem of this Index seems to be the use of absolute numbers without normalization. Furthermore, measures of quality are reintroduced on the basis of reputation of journals rather than quality (impact) of single publications.
