After a good introduction to what IA is, the authors take the reader through the basic principles of this discipline. In this section, the authors discuss organization and labeling of systems, navigation, and searching. In the third section of the book, the authors go into the practice of actually implementing the principles in the previous section. Finally, the authors examine case studies from two different sites, where they examine how IA fit into the overall goal of the application.

I felt this book gave me a basic understanding of what Information Architecture is, and what types of things to look out for in developing an IA strategy. I would recommend this book if you have large amounts of data you want web users to have access to.
