  A review is given for the theoretical framework to give a reliable prediction
of the superconducting transition temperature Tc from first principles,
together with a practical strategy for its application to actual materials with
illustrations of the results of Tc calculated for superconductors in the
weak-coupling region like the alkali and alkaline-earth intercalated graphites
as well as those in the strong-coupling region like the alkali-doped
fullerides.
