Summary 
Alkalidoped fullerides have attracted strong interest since their production became possible about fifteen years ago. This book presents work which may solve intriguing problems arising from a variety of remarkable properties. For example, these solids are superconductors with high transition temperatures, although the similarity between the electronic and phonon energy scales should suppress superconductivity. Moreover, the IoffeRegel condition for electrical conductivity is strongly violated. The book shows why superconductivity is nevertheless possible, owing to a local pairing mechanism. The IoffeRegel condition is derived quantummechanically, and it is explained why the underlying assumptions are violated for fullerides and highTc cuprates, for example. The book treats electronic and transport properties, reviewing theoretical and experimental results. It focuses on superconductivity, electrical conductivity and metalinsulator transitions, emphasizing the electronelectron and electronphonon interactions as well as the JohnTeller effect
