The book entitled "Life - My Story in History" was published on Tuesday by HarperCollins, initially in seven languages worldwide.
The 270-page work essentially consists of the recording of several conversations that Italian TV journalist Fabio Marchese Ronga has had with the Pope in recent months.
To introduce the respective answers, the author describes historical and private events surrounding the life of Francis.
Several passages from the book have already become known in the past week, including the Pope's comments on war and peace, anti-Semitism and clarifications on his relationship with his resigned predecessor Benedict XVI.
Much that is already known, but also new details
It also contains much that is already known, but also new details, such as his support for people resisting the military dictatorship in Argentina (1976-1983) or his "internal exile" by the Jesuits to Cordoba (1990-1992), the reasons for which, however, remain unclear.
The Pope also reports on the time of "cohabitation" with the resigned German Pope Benedict XVI in the Vatican and mentions that he had read his predecessor's writings and speeches carefully and agreed with him on many points.
When asked about a possible resignation from office, he emphasised that he would only consider this appropriate in an extreme health emergency.
Regarding the invitation to his home country of Argentina by President Javier Milei, Francis explains in the book: "I hope that I will be able to travel, even if travelling is no longer as easy for me as it used to be, especially because of the great distances. We'll see what the Lord decides for me."
And on the war in Ukraine: "So much pain, so much suffering. And for what? All out of imperialist interests or murderous cynicism. That is outrageous!"
