For someone fairly new to the area, I can't recommend this book enough.
The book is well researched and written in an accessible style - sometimes not an easy thing to do in an area like this.
A couple of minor points:
- The book actually gives some useful pointers for IA for Intranets as well as 'the web' - this should be made more clear
- I don't feel that the book gives adequate information on site maps
- Some of the illustrations look old - this has the result of the book looking like it's out of date - it isn't!
These are minor gripes, however, and should not distract you from buying this book.
But please, 4 years on, can we have a second edition??
