This book was first published by Princeton University Press in 1957. Although the text was completed in May 1956 (50 years ago!), it is so comprehensive and well-written that it is still very useful today.

The book begins with an introductory chapter that also gives an overall picture of the content. This includes:

- The general problem of integration;
- Some classical topics (on differentiation and integration and manifolds);
- Indications of general theory.

The main body of the book has three parts, and I will list the chapters because I think it is the only way one can realize the complexity of the work and its connections/overlapping with algebraic topology.

**Part I: Classical Theory** contains chapters on Grassmann algebra, Differential forms, Riemann integration theory, Smooth manifolds;
**Part II: general Theory** contains Abstract integration theory, Some relations between chains and functions, General properties of chains and cochains, Chains and cochains in open sets;
**Part III: Lebesgue Theory** contains Flat cochains and differential forms, Lipschitz mappings, Chains and additive set functions.

To make the book self-contained, the author introduced appendices on Vector and linear spaces, Geometric and topological preliminaries, as well as Analytical preliminaries.

In short, this is a very good book (otherwise, how could it have been republished after 50 years?) that can be used as a textbook for a course on geometric integration, but mostly as a comprehensive reference for anybody interested in the subject.
