Homology Theory

'This book achieves the purpose of providing an introduction which reaches the developing parts of the subject, and for those who already know a little algebraic topology is by far the best textbook for further study.' D.G. Palmer in Proceedings of the Edinburgh Mathematical Society
'This is a badly needed book. It does an excellent job of carrying the serious beginning student of algebraic topology to a genuine acquaintance with the field.' A. Heller in American Mathematical Reviews
'The book is written with great skill and contains a large number of exercises. The authors constantly emphasise the geometrical nature of the ideas they examine'. P.S. Alexandrov in the Preface to the Russian edition
