I think this book should be for everyone who is interested in baking bread.

It is a great book, but still very much in print and under copyright restrictions. The download link you posted has thus been removed.
The Bread Builders can be bought on Amazon or your local book store.
Kiko Denzer's book as well as Alan Watt's are great too.
Thank you, Floydm! Both of these books are just wonderful. Already booked them :)
