This review presents a comprehensive summary of theoretical investigations and experimental searches for spin-dependent interactions beyond the standard model. These interactions may be mediated by various types of exotic bosons, and their existence and properties may, in turn, explain the nature of dark matter and dark energy. The described experiments also probe the discrete fundamental symmetries of nature.
