I would have liked to see a bibliography. A suggested further reading list is included and is welcomed, but why are they all books by either Buzan or his co-authors? - I suppose advertising is not a bad thing but as Buzan himself says in the book "the brain constantly seeks new knowledge and information", and references to new sources may have proved useful?

I can recommend this book, it is a good companion to "The Mind Map Book : How to Use Radiant Thinking to Maximize Your Brain's Untapped Potential". However, the system does not work by simply reading the books - you have to implement and use them.
