Abstract
A theoretical overview of the classes of superconductors encompassing (a) high-T C cuprate, (b) iron-based, and (c) aromatic superconductors is given. Emphasis is put on the multiband natures of all the three classes, where the differences in the multiorbits and their manifestations in the electronic structures and pairing are clarified. From these, future directions and prospects are discussed.
