From the review:

The most impressive aspect of the book though is the up-to-date discussion. Not content with describing what makes a good site map and how to present it we get the author’s well-thought out ideas on whether sitemaps are indeed up to the task in a world of user-generated content, search and non-hierarchical site structures (probably not apparently). In another chapter a disussion of the problems involved in carrying out a large content inventory are accompanied by details of why the perfect tool for the job is difficult to come by.
