  We report here the completion of the electronic structure of the majority of
the known stoichiometric inorganic compounds, as listed in the International
Crystal Structure Data-base (ICSD). We make a detailed comparison of the
electronic structure, crystal geometry and chemical bonding of cuprate high
temperature superconductors, with the calculated over sixty thousand electronic
structures. Based on compelling similarities of the electronic structures in
the normal state and a data-filtering technique, we propose that high
temperature superconductivity is possible for electron- or hole-doping in a
much larger group of materials than previously considered. The indentified
materials are composed of over one hundred layered compounds, most which
hitherto are untested with respect to their super conducting properties. Of
particular interest are the following materials; Ca$_2$(CuBr$_2$O$_2$),
K$_2$CoF$_4$, Sr$_2$(MoO$_4$) and Sr$_4$V$_3$O$_{10}$, which are discussed in
detail.
