The Coulomb sum rule is evaluated for a large class of nuclei up to the heavy ones. Beyond mean-field effects, short-range correlations are taken into account. The latter decrease the sum rule in the whole considered momentum range. The size of the reduction increases with the average proton density reaching its maximum for medium heavy nuclei.
