Pablo Neruda died before this manuscript was completed and the final editing was done by his widow Matilde and Miguel Otero Silva.
This is a stated first edition, 1977, full size soft cover, published by Farrar, Straus and Giroux. Translation from the Spanish is by Hardie St. Martin. 350 pages plus chronology and index.
This is from Neruda's intro to the memoirs.
"...there are gaps here and there, and sometimes they are also forgetful, because life is like that.
What the memoir writer remembers is not the same thing the poet remembers. He may have lived less but he photographed much more, and he re-creates with special attention to detail. The poet gives us a gallery full of ghosts shaken by the fire and darkness of his time."
