Percolation as a model for informetric distributions: Fragment size distribution characterised by Bradford curves

It is shown how Bradford curves, i.e. cumulative rank-frequency functions, as used in informetrics, can describe the fragment size distribution of per colation models. This interesting fact is explained by arguing that some as pects of percolation can he interpreted as a model for the success-breeds-s uccess or cumulative advantage phenomenon. We claim, moreover, that the per colation model can be used as a model to study (generalised) bibliographies . This article shows how ideas and techniques studied and developed in info rmetrics and scientometrics can successfully be applied in other fields of science, and vice versa.
