\ BooknewsA survey of the main trends in two-dimensional magnetism research, starting with a general introduction to the field of low-dimensional magnetic systems, and progressing to a discussion of the theory of 2-D magnets, the applications of high and low temperature series expansions and spin waves, neutron scattering experiments on 2-D Ising and Heisenberg magnets, phase transitions, NMR and EPR, and field- induced phenomena in weakly anisotropic Heisenberg anti-ferromagnets.
