"Zachary Fisk and Hans-Rudolf Ott’s edited volume provides a timely review of this field and contains some wonderful articles that chart different aspects of the search for new superconducting materials. For me, a particular highlight was Fisk’s own contribution on superconductivity on the border of magnetism in which he outlines lucidly and clearly exactly how the phenomena compete and why the marginal stability of the 4f shell is so special in leading to Kondo behaviour and the heavy fermion phenomenon."--Contemporary Physics
