The strongest quality of this book lies in its truely international approach. The high quality illustrations focus on the seminal buildings of the modern-movement in architecture and cover the whole period between its early years in the 1920s right through to the 1970s. Each national working party of DOCOMOMO International (the society for the documentation and conservation of modern movement buildings) has submitted what they consider to be their own regions greatest contribution. However this has exposed the differences in opinion as to what constitutes Modern Movement architecture. For example there is rightly a strong focus in the Westrn Russia chapter on the Constructivist architects of the 20's and 30's. However there is no mention of any of the significant works of the 60's and 70's. Whilst the entry for Scotland, a more balanced entry, includes an oilrig of the 1970s as an example. The critisism of imbalance stands for most countries contributions. However this is generally an excelent reference volume and represents a rare holistic insight into what, in light of this title, is rightly refered to as the International Movement.
