Sharing content of a book on blogging website

Its encouraging to see that you are prepared to act in the right spirit in an honest manner, when you could have plagiarized from the book and probably got away with it. A few questions to help me in answering your query:

1. Are you monetising your blog?
2. What proportion of your blog content (a rough percent) would be purely the book excerpt?
3. How far are you going to add to and develop the ideas expressed in the copyrighted book?
4. Does the book publisher expressly provide any contact information for readers intending to reproduce from the book? (not usual, but some authors do give such information).
