Mind maps are used in as much detail you want or need. It will all come down to your purpose for PhotoReading the book and how much information you want to retain.
You could mind map each chapter of a book and, then 'join' them together to create a super mind map.
You can use the table of contents to help you.
Forget the mind map for a second. If you had to describe to somebody in 10 keywords what you have just read - what are those keywords? That's your mind map. Mindmaps can also include images.
Mindmaps follow the 80/20 rule. What 20% covers 80% of the book?
And in case I want to retain the maximum amount of information I can from a book, what do I have to do?
