Two case studies of the Hirsch index and some of its variants — •Michael Schreiber — Institut für Physik, Technische Universität Chemnitz

The h-index was introduced by Hirsch to quantify the impact of the publications of a scientist by measuring the number of citations. I present an analysis of two data sets, one for 8 famous physicists and another [1,2] for 26 not-so-prominent colleagues. Difficulties with the determination of the index and its interpretation are discussed. In addition the influence of self-citations is analyzed. Some variants of the index are investigated. A new modification is suggested in order to take the number of co-authors appropriately into account. By means of this new m-index it is possible to attribute the fame for multi-authored manuscripts in a fair way.
