Abstract
A simple stochastic model, based upon mixtures of non-homogeneous Poisson p rocesses, is proposed to describe the citation process in the presence of a geing/obsolescence. Particular emphasis is placed upon investigation of the first-citation distribution where it is shown that in the presence of agei ng there will inevitably be never-cited items. Conditions are given which s how how the model is capable of modelling the various shapes of first-citat ion distributions reported in the literature. In particular, the essential link between the first-citation distribution and the obsolescence distribut ion is established.
