I shall review the ubiquitous presence in all branches of science of quasi-power law distributions (i.e., distributions following pure power laws for large values of the argument but remaining finite, usually exponential, for small values). A number of possible sources of such distributions will be presented and discussed in more detail. Some remaining problems will be outlined.
