The contributions of superconducting fluctuations to the specific heat of
dirty superconductors are calculated, including quantum and classical
corrections to the `usual' leading Gaussian divergence. These additional terms
modify the Ginzburg criterion, which is based on equating these
fluctuation-generated contributions to the mean-field discontinuity in the
specific heat, and set limits on its applicability for materials with a low
transition temperature.
