{"doi":"10.1002/ejoc.200801243","title":"Hirsch‐Type Index Values for Organic Chemistry Journals: A Comparison of New Metrics with the Journal Impact Factor","abstract":"<jats:title>Abstract</jats:title><jats:p>In August 2005, Jorge Hirsch introduced with the <jats:italic>h</jats:italic> index a new research performance indicator. His index is an original and simple new measure that incorporates both quantity and visibility of publications. Since 2005, a number of corrections and complementary indices to the <jats:italic>h</jats:italic> index as well as single‐number alternatives have already been put forward. We examine in the present study the <jats:italic>h</jats:italic> index and the most important <jats:italic>h</jats:italic> index variants that have been proposed and discussed in the literature. The aim of the analysis is to determine empirically the extent to which the usage of the <jats:italic>h</jats:italic> index and its variants for measuring the performance of journals results in an incremental contribution against the Journal Impact Factor (JIF). JIF, <jats:italic>h</jats:italic> index, and different variants of the <jats:italic>h</jats:italic> index were calculated for 20 organic chemistry journals. As the findings reveal high intercorrelations, the different performance measures could be called redundant in empirical application. (© Wiley‐VCH Verlag GmbH &amp; Co.
