Abstract: The outgrow index measures to which extent an article outgrows - in 
terms of citations - the references on which it is based. In this article, three 
types of time series of outgrow indices and one outgrow index matrix are 
introduced. Examples of these time series are given illustrating the newly 
introduced concepts. These time series expand the toolbox for citation analysis 
by focusing on a specific subnetwork of the global citation network. It is stated 
that citation analysis has three application areas: information retrieval, 
research evaluation and structural citation network studies. This contribution is 
explicitly placed among structural network studies. (C) 2011 Elsevier Ltd. All
