superconducting reaching a maximum critical temperature of the order of  30 K )at the optimal doping. LDA fails to describe the insulating character of the parent compound. Conventional LDA estimates of the electron phonon coupling, within Migdal Eliasberg theory, predicted that the electron phonon coupling in the doped compound is of the order of XXX and therefore cannot account for its superconductivity. \cite{Meregalli_1998}  In ref XXX ref\cite{Yin_2013}  we found that in BaBiO 3 there is a substantial correlation enhancement of λ relative to its LDA estimate, and that this enhancement is  responsible for superconductvity in BaKBiO3 (λ ~ .1 ) . We argue that this occurs in many other materials which are  proximate to an insulating state, and accounts for the superconductivity on the “Other High Temperature
