Pope: "Anyone is free to contradict me"

In the Corriere della Sera there's more info on the Pope's new book.
Roughly translated, the 1st two paragraphs of the article read as follows:

Vatican City - Benedict XVI has finished writing his book about Jesus Christ. It is entitled "Jesus of Nazareth. From the Baptism (sic) to the Transfiguration" and is a sort of theological summary (or Summa Theologica) about the figure of Christ. The announcement of the issuing of the first of the two volumes of the work, which will be printed by Rizzoli next spring, was given in the Vatican press room.
"This book is absolutely not a magisterial act, but is purely an expression of my personal search for the Lord's face. Therefore anyone is free to contradict me" notes Benedict XVI. In the preface Joseph Ratzinger clarifies that the work is not to be held binding from the Magisterial point of view, "I only ask that sympathy from my readers without which there is no understanding."

The third paragraph is simply blurb from the printers.
