Many years ago I read a book in Spanish titled "El Padre Pio De Pietrelcina". To this day it is the most accurate book that I have read on this man. My own opinion is that it leaves all others for dead.
It was written by a Spanish lawyer back in the 80's.
I uploaded it some time ago to archive.org http://archive.org/details/ElPadrePioDePietrelcina
On this same page in archive.org can be added other files. Now, this book is so full of pics with Spanish explanations below, that it would be difficult to translate. But the main text could be translated.
I am more than twenty years without using Spanish and my intellectual capacity is somewhat diminished thru illness. Plus like most of us I don't have time.
If any individual or group is interested in translating this book into any language and in providing me with the file I can upload it alongside the original Spanish. info@essan.org
