The theory of cohesive properties of ionic crystals is discussed with reference to some calculations aimed at such properties (cohesive energies, lattice constants, compressibilities, elastic constants, etc.). These calculations are classified as nonempirical LCAO, semiempirical LCAO, and density functional approaches. These procedures are analyzed and compared. Finally possible improvements of some of the methods are discussed.
