Problems of the rotating models are discussed, their general kinematic properties and dynamical realizations are described. A particular attention is paid to the discussion of possible observational effects which could be used to estimate or to put limits on the cosmic rotation.Revtex, 85 pages, no figures; ref. list is updated as compared to the published versionAstrophysicsGeneral Relativity and Quantum CosmologyOn physical foundations and observational effects of cosmic rotationtext
