The most important experimental results in charmonium physics in the energy region above the threshold for open-charm production that were obtained in recent years are surveyed. The first measurements of the exclusive cross sections for e{sup +}e{sup -} {yields} DD-bar, DD-bar*, and D* D-bar* processes are discussed along with the discovered decay {psi}(4415) {yields} bar D{sub 2}{sup *} (2460). The properties of charmonium-like states, including the group of states Y (4260), Y (4325), and Y (4660) with quantum numbers of J{sup PC} = 1{sup --}; the X(3940) and X(4160) states discovered in the process of double charmonium production in e{sup +}e{sup -} annihilation; and the X(3872), Y(3940), and Z{sup {+-}}(4430) states found in B-meson decays, are presented.
