We present new integral formulas for Coulombic lattice sums that arise in solid state physics, material science, and complex analysis. Unlike Ewald summation, which can yield approximate integral representations, the formulas described here are exact. Simple quadrature rules with modest numbers of nodes yield highly accurate results.
