Abstract: In order to take multiple co-authorship appropriately into 
account, a straightforward modi. cation of the Hirsch index was recently 
proposed. Fractionalised counting of the papers yields an appropriate 
measure which is called the h(m)-index. The effect of this procedure is 
compared in the present work with other variants of the h-index and found 
to be superior to the fractionalised counting of citations and to the 
normalization of the h-index with the average number of authors in the h-
core. Three fictitious examples for model cases and one empirical case are 
analysed. (C) 2008 Elsevier Ltd. All rights reserved.
